xml:lang="en"><title>Abstract</title><p>Following a request from the European Commission, the <styled-content style="fixed-case" toggle="no">EFSA</styled-content> Plant Health Panel updated its pest categorisation of <italic>Xylella fastidiosa</italic>, previously delivered as part of the pest risk assessment published in 2015. <italic>X. fastidiosa</italic> is a Gram‐negative bacterium, responsible for various plant diseases, including Pierce's disease, phony peach disease, citrus variegated chlorosis, olive quick decline syndrome, almond leaf scorch and various other leaf scorch diseases. The pathogen is endemic in the Americas and is present in Iran. In the <styled-content style="fixed-case" toggle="no">EU</styled-content>, it is reported in southern Apulia in Italy, on the island of Corsica and in the Provence‐Alpes‐Côte d'Azur region in France, as well as in the Autonomous region of Madrid, the province of Alicante and the Balearic Islands in Spain. The reported status is ‘transient, under eradication’, except for the Balearic Islands, Corsica and southern of Apulia, where the status is ‘present with a restricted distribution, under containment’. The pathogen is regulated under Council Directive 2000/29/<styled-content style="fixed-case" toggle="no">EC</styled-content> and through emergency measures under <ext-link ext-link-type="uri" xlink:href="http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32015D0789">http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32015D0789</ext-link> (as amended <ext-link ext-link-type="uri" xlink:href="http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32017D2352">http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32017D2352</ext-link>). The pest could enter the <styled-content style="fixed-case" toggle="no">EU</styled-content> via host plants for planting and via infectious insect vectors. The host range includes hundreds of host species listed in the <styled-content style="fixed-case" toggle="no">EFSA</styled-content> host plant database. In the <styled-content style="fixed-case" toggle="no">EU</styled-content>, host plants are widely distributed and climatic conditions are favourable for its establishment. <italic>X. fastidiosa</italic> can spread by movement of host plants for planting and infectious insect vectors. <italic>X. fastidiosa</italic> is known to cause severe direct damage to major crops including almonds, citrus, grapevines, olives, stone fruits and also forest trees, landscape and ornamental trees, with high impacts. The criteria assessed by the Panel for consideration as a potential Union quarantine pest are met (the pathogen is present in the <styled-content style="fixed-case" toggle="no">EU</styled-content>, but it has a restricted distribution and is under official control). <italic>X. fastidiosa</italic> is not considered as a regulated non‐quarantine pest (<styled-content style="fixed-case" toggle="no">RNQP</styled-content>) as the pathogen may spread also via insect vector transmission.</p></div></front><back><div1 type="bibliography"><listBibl><biblStruct><analytic><author><name

The pathogen is endemic in the Americas and is present in Iran. In the <styled-content style="fixed-case" toggle="no">EU</styled-content>, it is reported in southern Apulia in Italy, on the island of Corsica and in the Provence‐Alpes‐Côte d'Azur region in France, as well as in the Autonomous region of Madrid, the province of Alicante and the Balearic Islands in Spain. The reported status is ‘transient, under eradication’, except for the Balearic Islands, Corsica and southern of Apulia, where the status is ‘present with a restricted distribution, under containment’. The pathogen is regulated under Council Directive 2000/29/<styled-content style="fixed-case" toggle="no">EC</styled-content> and through emergency measures under <ext-link ext-link-type="uri" xlink:href="http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32015D0789">http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32015D0789</ext-link> (as amended <ext-link ext-link-type="uri" xlink:href="http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32017D2352">http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32017D2352</ext-link>). The pest could enter the <styled-content style="fixed-case" toggle="no">EU</styled-content> via host plants for planting and via infectious insect vectors. The host range includes hundreds of host species listed in the <styled-content style="fixed-case" toggle="no">EFSA</styled-content> host plant database. In the <styled-content style="fixed-case" toggle="no">EU</styled-content>, host plants are widely distributed and climatic conditions are favourable for its establishment. <italic>X. fastidiosa</italic> can spread by movement of host plants for planting and infectious insect vectors. <italic>X. fastidiosa</italic> is known to cause severe direct damage to major crops including almonds, citrus, grapevines, olives, stone fruits and also forest trees, landscape and ornamental trees, with high impacts. The criteria assessed by the Panel for consideration as a potential Union quarantine pest are met (the pathogen is present in the <styled-content style="fixed-case" toggle="no">EU</styled-content>, but it has a restricted distribution and is under official control). <italic>X. fastidiosa</italic> is not considered as a regulated non‐quarantine pest (<styled-content style="fixed-case" toggle="no">RNQP</styled-content>) as the pathogen may spread also via insect vector transmission.</p></abstract><kwd-group kwd-group-type="author-generated"><kwd id="efs25357-kwd-0001">European

into the Community of organisms harmful to plants or plant products and against their spread within the Community establishes the present European Union plant health regime. The Directive lays down the phytosanitary provisions and the control checks to be carried out at the place of origin on plants and plant products destined for the Union or to be moved within the Union. In the Directive's 2000/29/EC annexes, the list of harmful organisms (pests) whose introduction into or spread within the Union is prohibited, is detailed together with specific requirements for import or internal movement.</p><p>Following the evaluation of the plant health regime, the new basic plant health law, Regulation (EU) 2016/2031<xref ref-type="fn" rid="efs25357-note-1007">2</xref> on protective measures against pests of plants, was adopted on 26 October 2016 and will apply from 14 December 2019 onwards, repealing Directive 2000/29/EC. In line with the principles of the above mentioned legislation and the follow‐up work of the secondary legislation for the listing of EU regulated pests, EFSA is requested to provide pest categorisations of the harmful organisms included in the annexes of Directive 2000/29/EC, in the cases where recent pest risk assessment/pest categorisation is not available.</p></sec><sec id="efs25357-sec-0005"><label>1.1.2</label><title>Terms of reference</title><p>EFSA is requested, pursuant to Article 22(5.b) and Article 29(1) of Regulation (EC) No 178/2002<xref ref-type="fn" rid="efs25357-note-5003">3</xref>, to provide scientific opinion in the field of plant health.</p><p>EFSA is requested to prepare and deliver a pest categorisation (step 1 analysis) for each of the regulated pests included in the appendices of the annex to this mandate. The methodology and template of pest categorisation have already been developed in past mandates for the organisms listed in Annex II Part A Section II of Directive 2000/29/EC. The same methodology and outcome is expected for this work as well.</p><p>The list of the harmful organisms included in the annex to this mandate comprises 133 harmful organisms or groups. A pest categorisation is expected for these 133 pests or groups and the delivery of the work would be stepwise at regular intervals through the year as detailed below. First priority covers the harmful organisms included in Appendix 1, comprising pests from Annex II Part A Section I and Annex II Part B of Directive 2000/29/EC. The delivery of all pest categorisations for the pests included in Appendix 1 is June 2018. The second priority is the pests included in Appendix 2, comprising the group of <italic>Cicadellidae</italic> (non‐EU) known to be vector of Pierce's disease (caused by <italic>Xylella fastidiosa</italic>), the group of <italic>Tephritidae</italic> (non‐EU), the group of potato viruses and virus‐like organisms, the group of viruses and virus‐like organisms of <italic>Cydonia</italic> Mill., <italic>Fragaria</italic> L., <italic>Malus</italic> Mill., <italic>Prunus</italic> L., <italic>Pyrus</italic> L., <italic>Ribes</italic> L., <italic>Rubus</italic> L. and <italic>Vitis</italic> L.. and the group of <italic>Margarodes</italic> (non‐EU species). The delivery of all pest categorisations for the pests included in Appendix 2 is end 2019. The pests included in Appendix 3 cover pests of Annex I part A section I and all pests categorisations should be delivered by end 2020.</p><p>For the above mentioned groups, each covering a large number of pests, the pest categorisation will be performed for the group and not the individual harmful organisms listed under “such as” notation in the Annexes of the Directive 2000/29/EC. The criteria to be taken particularly under consideration for these cases, is the analysis of host pest combination, investigation of pathways, the damages occurring and the relevant impact. Finally, as indicated in the text above, all references to ‘non‐European’ should be avoided and replaced by ‘non‐EU’ and refer to all territories with exception of the Union territories as defined in Article 1 point 3 of Regulation (EU) 2016/2031</p><p>The list of harmful organisms for which pest categorisation is requested is provided below in Sections <xref rid="efs25357-sec-0006" ref-type="sec">1.1.2.1</xref>, <xref rid="efs25357-sec-0007" ref-type="sec">1.1.2.2</xref> and <xref rid="efs25357-sec-0008" ref-type="sec">1.1.2.3</xref>. Such list includes <italic>Xylella fastidiosa,</italic> as the causal agent of diseases such as the “Citrus variegated chlorosis” and the “Peach phony rickettsia” as listed in the Annexes of Directive 2000/29/EC. With mandate ARES (2017) 6346828 ‐ 22/12/2017, the European Commission has requested that the pest categorisation of <italic>Xylella fastidiosa</italic> should be jointly delivered by June 2018 together with the update of the <italic>Xylella</italic> host plants database, in order to provide a common and comprehensive base for the follow‐up development of an update of the pest risk assessment for <italic>X. fastidiosa</italic> by March 2019.</p><sec id="efs25357-sec-0006"><label>1.1.2.1</label><title>Terms of Reference: Appendix 1</title><p>List of harmful organisms for which pest categorisation is requested.

Therefore, to facilitate the decision‐making process, in the conclusions of the pest categorisation, the Panel explicitly addresses each criterion for a Union quarantine pest and for a Union regulated non‐quarantine pest (RNQP) in accordance with Regulation (EU) 2016/2031 on protective measures against pests of plants, and includes additional information required in accordance with the specific terms of reference received by the European Commission. In addition, for each conclusion, the Panel provides a short description of its associated uncertainty.</p><p>Table <xref rid="efs25357-tbl-0001" ref-type="table">1</xref> presents the Regulation (EU) 2016/2031 pest categorisation criteria on which the Panel bases its conclusions. All relevant criteria have to be met for the pest to potentially qualify either as a quarantine pest or as a RNQP. If one of the criteria is not met, the pest will not qualify. A pest that does not qualify as a quarantine pest may still qualify as a RNQP that needs to be addressed in the opinion. For the pests regulated in the protected zones only, the scope of the categorisation is the territory of the protected zone; thus, the criteria refer to the protected zone instead of the EU territory.</p><p>It should be noted that the Panel's conclusions are formulated respecting its remit and particularly with regard to the principle of separation between risk assessment and risk management (EFSA founding regulation (EU) No 178/2002); therefore, instead of determining whether the pest is likely to have an unacceptable impact, the Panel will present a summary of the observed pest impacts. Economic impacts are expressed in terms of yield and quality losses and not in monetary terms, whereas addressing social impacts is outside the remit of the Panel, in agreement with EFSA guidance on a harmonised framework for pest risk assessment (EFSA PLH Panel, <xref rid="efs25357-bib-0047" ref-type="ref">2010</xref>).</p><table-wrap id="efs25357-tbl-0001" xml:lang="en" orientation="portrait" position="float"><label>Table 1</label><caption><p>Pest categorisation criteria under evaluation, as defined in Regulation (EU) 2016/2031 on protective measures against pests of plants (the number of the relevant sections of the pest categorisation is shown in brackets in the first column</p></caption><table frame="hsides" rules="groups"><col style="border-right:solid 1px #000000" span="1"></col><col style="border-right:solid 1px #000000" span="1"></col><col style="border-right:solid 1px #000000" span="1"></col><col style="border-right:solid 1px #000000" span="1"></col><thead valign="top"><tr style="border-bottom:solid 1px #000000"><th align="left" valign="top" rowspan="1" colspan="1">Criterion of pest categorisation</th><th align="left" valign="top" rowspan="1" colspan="1">Criterion in Regulation (EU) 2016/2031 regarding Union quarantine pest</th><th align="left" valign="top" rowspan="1" colspan="1">Criterion in Regulation (EU) 2016/2031 regarding protected zone quarantine pest (Articles 32–35)</th><th align="left" valign="top" rowspan="1" colspan="1">Criterion in Regulation (EU) 2016/2031 regarding Union regulated non‐quarantine pest</th></tr></thead><tbody><tr><td align="left" rowspan="1" colspan="1">Identity of the pest (Section <xref rid="efs25357-sec-0017" ref-type="sec">3.1</xref>)</td><td align="left" rowspan="1" colspan="1">Is the identity of the pest established, or has it been shown to produce consistent symptoms and to be transmissible?</td><td align="left" rowspan="1" colspan="1">Is the identity of the pest established, or has it been shown to produce consistent symptoms and to be transmissible?</td><td align="left" rowspan="1" colspan="1">Is the identity of the pest established, or has it been shown to produce consistent symptoms and to be transmissible?</td></tr><tr><td align="left" rowspan="1" colspan="1">Absence/presence of the pest in the EU territory (Section <xref rid="efs25357-sec-0027" ref-type="sec">3.2</xref>)</td><td align="left" rowspan="1" colspan="1">Is the pest present in the EU territory?If present, is the pest widely distributed within the EU?

It is transmitted by xylem sap‐feeding insects, and causes major plant diseases. These diseases are characterised by symptoms often similar to those caused by water stress. Many host plants remain symptomless while infected by the bacterium, and may serve as reservoirs in the environment (Hopkins and Purcell, <xref rid="efs25357-bib-0091" ref-type="ref">2002</xref>), while for others, the infection produces rapid death (Purcell and Saunders, <xref rid="efs25357-bib-0138" ref-type="ref">1999</xref>; Martelli et al., <xref rid="efs25357-bib-0111" ref-type="ref">2016</xref>). Colonisation patterns are complex and depend on the host plant and the pathogen genotype (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>).</p><p>Generally, when plants are susceptible, the bacteria move systemically through the xylem vessels and are accessible for acquisition by xylem‐feeding piercing‐sucking insect vectors after a variable length of time, according to the plant species (Hill and Purcell, <xref rid="efs25357-bib-0087" ref-type="ref">1995a</xref>,<xref rid="efs25357-bib-0088" ref-type="ref">b</xref>, <xref rid="efs25357-bib-0089" ref-type="ref">1997</xref>). Symptoms are usually linked to the occlusion of xylem vessels. Alternatively, the bacterium may also stay locally in some host plants, but still it may be acquired by insect vectors (Purcell and Saunders, <xref rid="efs25357-bib-0138" ref-type="ref">1999</xref>). The time lapse between inoculation and symptom appearance in plant is highly variable according to the plant species and age (generally shorter in herbaceous vs. woody hosts) and it is ranging from few months (e.g. a minimum of 3 months following artificial inoculation – pinprick stem inoculation – of <italic>X. fastidiosa</italic> to young <italic>Citrus</italic> seedlings, as indicated by Lopes et al., <xref rid="efs25357-bib-0105" ref-type="ref">2005</xref>) to more than 1 year (e.g. 12–14 months following artificial inoculation of <italic>X. fastidiosa</italic> to young olive seedlings, according to Saponari et al., <xref rid="efs25357-bib-0149" ref-type="ref">2016</xref>). The possibility that a non‐systemic host with only localised infection could still contribute to the spread of the disease to other plants, as shown previously (Hill and Purcell, <xref rid="efs25357-bib-0087" ref-type="ref">1995a</xref>,<xref rid="efs25357-bib-0088" ref-type="ref">b</xref>, <xref rid="efs25357-bib-0089" ref-type="ref">1997</xref>), was discussed in the EFSA pest risk assessment (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>) as well as in the other statements on the susceptibility of various plant species to <italic>X. fastidiosa</italic> strain CoDiRO (EFSA PLH Panel, <xref rid="efs25357-bib-0049" ref-type="ref">2015b</xref>, <xref rid="efs25357-bib-0051" ref-type="ref">2016a</xref>).</p><p>Diseases caused by <italic>X. fastidiosa</italic> are usually the outcome of a complex interaction between the bacterium, host plants, including reservoirs and alternative ones, insect vectors and environmental conditions.</p><p><italic>X. fastidiosa</italic> is exclusively transmitted by xylem sap‐feeding insects belonging to the order Hemiptera, suborder Auchenorrhyncha – Cicadomorpha (= Clypeorrhyncha) (Redak et al., <xref rid="efs25357-bib-0142" ref-type="ref">2004</xref>). The bacteria are transmitted in a persistent manner, but there is no latency period following acquisition (Almeida et al., <xref rid="efs25357-bib-0004" ref-type="ref">2005</xref>). Vectors (both nymphs and adults) acquire the bacteria by feeding in the xylem and can inoculate the pathogen to healthy plants immediately after acquisition. Bacteria are restricted to the alimentary canal and do not systemically infect the insect body. They adhere to and multiply in the precibarium and the cibarium (parts of the foregut). This implies that vectors lose infectivity with moulting, as the foregut is of ectodermal origin and is renewed with moulting. Therefore, newly emerged adults must feed again on an infected plant to become infectious and spread <italic>X. fastidiosa</italic>. Once infected, adult vectors can transmit the bacterium during their whole lifetime, as multiplies and persists in the vector foregut (Almeida et al., <xref rid="efs25357-bib-0004" ref-type="ref">2005</xref>). The bacterium is not transovarially transmitted to the progeny of the vector (Freitag, <xref rid="efs25357-bib-0069" ref-type="ref">1951</xref>). Winged adults, because of their high mobility and of their persistent infection, are mostly responsible for <italic>X. fastidiosa</italic> spread. Since the bacterium is restricted to the foregut (Purcell and Finlay, <xref rid="efs25357-bib-0136" ref-type="ref">1979</xref>), the number of bacterial cells per insect is low. But very few live bacterial cells in the vector's foregut are required for transmission (Hill and Purcell, <xref rid="efs25357-bib-0087" ref-type="ref">1995a</xref>,<xref rid="efs25357-bib-0088" ref-type="ref">b</xref>). Therefore, a sensitive diagnostic tool, such as polymerase chain reaction (PCR), is needed to detect the presence of <italic>X. fastidiosa</italic> in the insect vectors. Enzyme‐linked immunosorbent assay (ELISA) is not sensitive enough to detect <italic>X. fastidiosa</italic> in the vector insects. Importantly, even PCR (or qPCR and other related methods) have so far not been shown to provide robust results in insects. In fact, according to Cornara et al. (<xref rid="efs25357-bib-0032" ref-type="ref">2016</xref>), due to the insufficient sensitivity of PCR on insects, the relationship between test plant infection status and spittlebug infection status (as determined by PCR) is not strong. However, the same paper indicates that vector transmission to plants and <italic>X. fastidiosa</italic> population size in the vector (as determined by qPCR) are significantly correlated. A more sensitive nested PCR technique has recently been proposed (Cruaud et al., <xref rid="efs25357-bib-0036" ref-type="ref">2018</xref>), but has not yet been applied in transmission experiments to see whether the transmission and pathogen detection in the vector are significantly correlated.</p><p>Although <italic>X. fastidiosa</italic> transmission is restricted to xylem sap‐feeding insects with piercing‐sucking mouthparts, insect transmission of <italic>X. fastidiosa</italic> is known to lack specificity. Therefore, all xylem sap‐feeding insects are considered vectors, which assumption has not so far been disproven (Frazier, <xref rid="efs25357-bib-0067" ref-type="ref">1944</xref>; Purcell, <xref rid="efs25357-bib-0133" ref-type="ref">1989</xref>; Almeida et al., <xref rid="efs25357-bib-0004" ref-type="ref">2005</xref>). However, transmission efficiency varies substantially depending on insect species, host plants and <italic>X. fastidiosa</italic> genotype (Redak et al., <xref rid="efs25357-bib-0142" ref-type="ref">2004</xref>; Lopes et al., <xref rid="efs25357-bib-0106" ref-type="ref">2010</xref>; Almeida, <xref rid="efs25357-bib-0001" ref-type="ref">2016</xref>).</p><p>As reported in the previous EFSA opinion (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>), ‘the ecology of <italic>X. fastidiosa</italic> diseases is the outcome of complex biotic and abiotic interactions. Although general insights from one disease system are useful for another, ecological parameters are not necessarily transferable’.</p><p>‘Despite the fact that <italic>X. fastidiosa</italic> has a notoriously large alternative host plant range, the epidemiological importance of its hosts varies. The spring spread of <italic>X. fastidiosa</italic> from host plants in riparian habitats (i.e. along creeks/rivers) into vineyards in coastal areas of northern California is well established (Purcell, <xref rid="efs25357-bib-0131" ref-type="ref">1974</xref>). Although there is vector spread of <italic>X. fastidiosa</italic> from grapevine to grapevine in late summer and autumn, only the spring spread from alternative hosts to the grapevine is of epidemiological importance, because freezing winter temperatures may eliminate <italic>X. fastidiosa</italic> from grapevines inoculated after spring months (reviewed in Hopkins and Purcell, <xref rid="efs25357-bib-0091" ref-type="ref">2002</xref>). A similar scenario occurs in the Central Valley of California (USA), where insect vectors move to vineyards for brief flights from alfalfa fields, but there is no further spread from grapevine to grapevine (Purcell and Frazier, <xref rid="efs25357-bib-0137" ref-type="ref">1985</xref>). Few Pierce's diseased grapevines in regions without freezing winter temperatures recover. The opposite scenario occurs with citrus variegated chlorosis in Brazil. In that case, <italic>X. fastidiosa</italic> is also known to colonise a wide range of weeds associated with citrus orchards (Lopes et al., <xref rid="efs25357-bib-0105" ref-type="ref">2005</xref>), but disease spreads primarily from citrus to citrus (Laranjeira et al., <xref rid="efs25357-bib-0099" ref-type="ref">1998</xref>). Alternative hosts, in this case, may be important for maintenance of the pathogen in the environment, and provide a habitat for insect vectors, but their epidemiological impact is deemed to be low’.</p><p>Similarly, epidemics of Pierce's disease of grapevines in California, USA, may also have distinct characteristics if vector species are different. In northern coastal California, spread is driven by adult <italic>Graphocephala atropunctata</italic> leafhoppers that overwinter in riparian areas adjacent to vineyards. In spring they migrate to vineyards and infect vines, leading to a disease distribution radiating from the overwintering habitat of vectors. After the introduction of the invasive species <italic>Homalodisca</italic> <italic>vitripennis</italic> to southern California, Pierce's disease epidemics had devastating consequences for vineyards in Temecula Valley, where entire vineyards were symptomatic (i.e. no edge effect). In this case, insect vectors overwintered on adjacent citrus plants, reaching extremely large populations (one to two million per hectare) (Coviella et al., <xref rid="efs25357-bib-0035" ref-type="ref">2006</xref>) that were subsequently‐distributed throughout vineyards (Perring et al., <xref rid="efs25357-bib-0127" ref-type="ref">2001</xref>), leading to an extensive disease spread.</p><p>In the Americas, most diseases caused by <italic>X. fastidiosa</italic> are vectored by sharpshooter leafhoppers. In Europe, spittlebugs are much more abundant and diverse than sharpshooter leafhoppers, but not much is known about their biology, ecology and role as vectors. In addition, agricultural practices and environmental conditions, including the landscape and climate, are extremely variable in the EU (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>).</p><p>After the detection of <italic>X. fastidiosa</italic> in Europe in October 2013, two large research projects <underline underline-style="single">POnTE</underline> and <underline underline-style="single">XF‐ACTORS</underline> were funded by EU Horizon 2020 programme to investigate the biology and the control of <italic>X. fastidiosa</italic> in Europe.

Another reason is that <italic>X. fastidiosa</italic> infects a wide range of host plant species asymptomatically. Symptom development depends on host plant species–<italic>X. fastidiosa</italic> genotype (Almeida and Purcell, <xref rid="efs25357-bib-0002" ref-type="ref">2003</xref>) and is usually correlated with high bacterial populations within plants (Hill and Purcell, <xref rid="efs25357-bib-0087" ref-type="ref">1995a</xref>,<xref rid="efs25357-bib-0088" ref-type="ref">b</xref>; Newman et al., <xref rid="efs25357-bib-0114" ref-type="ref">2003</xref>). Because bacterial populations within plants are also correlated with the efficiency pathogen acquisition efficiency by its insect vectors (Hill and Purcell, <xref rid="efs25357-bib-0089" ref-type="ref">1997</xref>), plant species infected with low populations of <italic>X. fastidiosa</italic> may serve as an inefficient reservoir for vectors to acquire the bacterium (Almeida et al., <xref rid="efs25357-bib-0004" ref-type="ref">2005</xref>) (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>)’.</p><p>Whenever possible, isolation and achieving Koch's postulates is considered to be the ‘gold standard’ (EFSA, 2016b). Both EPPO and IPPC recommend isolation and pathogenicity tests in critical situations. Nevertheless, isolation of the bacteria is very difficult, even from symptomatic hosts (EPPO, <xref rid="efs25357-bib-0057" ref-type="ref">2018</xref>).</p><p>EPPO recently revisited its standards on diagnostic protocol for <italic>X. fastidiosa</italic> (PM 7/24(3)) (EPPO, <xref rid="efs25357-bib-0057" ref-type="ref">2018</xref>), following a thorough review of the literature and current practices in the EU. Briefly, two different procedures are proposed for the detection of the pathogen in plants and the insect vectors. For plant samples, at least two positive screening tests, based on different biological principles or targeting different parts of the genome, are required for a positive detection. Isolation is also recommended, followed by subsequent tests (including a pathogenicity test in critical cases) and subspecies determination. Attempts to assign a subspecies by molecular tests may also be performed. For the detection of <italic>X. fastidiosa</italic> in insects, the proposed methodology is simpler, with at least two methods based on different biological principles or targeting different parts of the genome. Subspecies determination is considered by EPPO as optional. Bacteria are usually present at lower concentrations in insect vectors, rendering isolation and detection more difficult. Recently, Cruaud et al. (<xref rid="efs25357-bib-0036" ref-type="ref">2018</xref>) proposed a nested PCR for the detection of <italic>X. fastidiosa</italic> in insects, in order to overcome the insufficient sensitivity of conventional and qPCR.</p><p>Several methods have been used to identify <italic>X. fastidiosa</italic> directly in petiole or stem cross‐sections, including serologically based methods such as dot‐immunobinding assay (EPPO, <xref rid="efs25357-bib-0055" ref-type="ref">2004</xref>), dot tissue blot immunobinding assay (Djelouah et al., <xref rid="efs25357-bib-0042" ref-type="ref">2014</xref>), ELISA (Sherald and Lei, <xref rid="efs25357-bib-0155" ref-type="ref">1991</xref>), membrane entrapment immunofluorescence (Hartung et al., <xref rid="efs25357-bib-0082" ref-type="ref">1994</xref>), immunofluorescence (Carbajal et al., <xref rid="efs25357-bib-0025" ref-type="ref">2004</xref>) or Western blot (Lee et al., <xref rid="efs25357-bib-0101" ref-type="ref">1992</xref>). Such methods are sometimes considered less sensitive than the isolation approach (French et al., <xref rid="efs25357-bib-0070" ref-type="ref">1978</xref>; Sherald and Lei, <xref rid="efs25357-bib-0155" ref-type="ref">1991</xref>).

Concomitantly in 2014, this genotype (ST53) was reported in Costa Rica (Nunney et al., <xref rid="efs25357-bib-0121" ref-type="ref">2014</xref>). Genomic analyses and evolutionary studies based on the draft genomes of isolates recovered in both countries have further confirmed that, within the subspecies <italic>pauca</italic>, the Apulian and Costa Rican isolates form a compact phylotype in a clade divergent from the South American <italic>pauca</italic> isolates (Giampetruzzi et al., <xref rid="efs25357-bib-0074" ref-type="ref">2017b</xref>). The clustering and distinctiveness of the ST53 isolates support the hypothesis of their common origin, and the limited genetic diversity among these isolates suggests this is a relatively new emerging clade within subspecies <italic>pauca</italic>. The low genetic variability detected upon comparative analysis of the draft genomes of more than 40 isolates recently recovered from diseased olive trees located in different municipalities of the Apulia, provide evidence of the recent introduction of <italic>X. fastidiosa</italic> in this region. Thus, the overall results of several genetic studies conclusively support (i) the Central American link of the Apulian strain causing disease in olive trees in southern Italy, and that (ii) the current epidemic is the consequence of a recent and single introduction (Sicard et al., <xref rid="efs25357-bib-0156" ref-type="ref">2017</xref>).</p><p>With regard to the distribution and spread of infections at field level, multiyear surveys in selected olive orchards have clearly shown that the infections progress rapidly and generally following an ‘aggregated patterns’, which indicates that secondary infections occur from the infected primary sources (Montes‐Borrego et al., <xref rid="efs25357-bib-0113" ref-type="ref">2017</xref>). The rapid progression of infections in the olive orchards is also accompanied by symptom severity. Although symptoms (scattered branch dieback) may vary depending on tree age, cultivar and agricultural practices, the canopies of the affected trees generally completely desiccate within 2–4 years.</p><p>Koch's postulates with the Apulian isolate have been fulfilled for olives, <italic>P. myrtifolia</italic> and <italic>N. oleander</italic> (Saponari et al., <xref rid="efs25357-bib-0150" ref-type="ref">2017</xref>). This study also provided experimental evidence for differential responses to the infections among olive cultivars. In agreement with previous studies (Giampetruzzi et al., <xref rid="efs25357-bib-0071" ref-type="ref">2016</xref>), inoculated plants of cultivar Leccino had lower bacterial titres and symptom scores. Similarly, in the same study, plants of the cultivar Frantoio and Coratina showed lower intensity of shoot dieback compared to the susceptible cultivar Cellina di Nardò.</p><p>Olive, being widely cultivated in the area concerned, is by far the most commonly infected and severely affected host in all the Apulian outbreaks (<ext-link ext-link-type="uri" xlink:href="http://www.emergenzaxylella.it">http://www.emergenzaxylella.it</ext-link>).

The recent establishment of <italic>X. fastidiosa</italic> in Apulia, Italy, Corsica in France and in the Balearic Islands in Spain confirms this statement.</p><p>Several approaches have been used to infer the suitability of climatic zones for <italic>X. fastidiosa</italic>, primarily the subspecies <italic>fastidiosa</italic> in the USA. Purcell and Feil (<xref rid="efs25357-bib-0135" ref-type="ref">2001</xref>) used isotherms of January temperatures for zones where Pierce's disease has a severe (4.5°C), occasional (1.7°C) or rare (–1.1°C) impact on grapes. Hoddle (<xref rid="efs25357-bib-0090" ref-type="ref">2004</xref>) used CLIMEX to produce maps of potential distribution for <italic>X. fastidiosa</italic> and its vector <italic>H. vitripennis</italic>, based on data from Feil and Purcell (<xref rid="efs25357-bib-0064" ref-type="ref">2001</xref>) and Feil (<xref rid="efs25357-bib-0063" ref-type="ref">2001</xref>). The optimum <italic>in vitro</italic> growth temperature for the bacteria <italic>X. fastidiosa</italic> subsp. <italic>fastidiosa</italic> is 28°C, and the bacterium did not grow <italic>in vitro</italic> at 12°C (Feil and Purcell, <xref rid="efs25357-bib-0064" ref-type="ref">2001</xref>). Anas et al. (<xref rid="efs25357-bib-0008" ref-type="ref">2008</xref>) used the number of winter days with temperatures below –12.2°C or –9.4°C to predict areas at risk of Pierce's disease and the effect of warming on disease severity. These temperature parameters have also been used for creating a NAPPFAST map for <italic>X. fastidiosa</italic> in the USA (Engle and Magarey, <xref rid="efs25357-bib-0054" ref-type="ref">2008</xref> in EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>). More recently, Bosso et al. (<xref rid="efs25357-bib-0021" ref-type="ref">2016</xref>) applied a Maxent model to detect and predict the current and future potential distribution of <italic>X. fastidiosa</italic> in the Mediterranean basin. In a recent study, Godefroid et al. (<xref rid="efs25357-bib-0075" ref-type="ref">2018</xref>) estimated the potential distribution of <italic>X. fastidiosa</italic> in Europe, based on different subspecies or types. They conclude that <italic>X. fastidiosa</italic> subsp. <italic>multiplex</italic> might pose a threat to most of Europe under current and future climate conditions, while Mediterranean coastal areas of Spain, Greece, Italy and France, the Atlantic coastal areas of France, Portugal and Spain and the south‐western regions of Spain and the lowlands in southern Italy are most threatened by, additionally to subsp. multiplex, subsp. fastidiosa and pauca.</p><p>‘In grapevines, plants may recover from infections during winter.

This is a very well reported phenomenon in grapevines (Feil and Purcell, <xref rid="efs25357-bib-0064" ref-type="ref">2001</xref>); on the west coast of the USA, it limits the northern spread of Pierce's disease (Hopkins and Purcell, <xref rid="efs25357-bib-0091" ref-type="ref">2002</xref>). ‘Although the recovery mechanism remains unknown, low winter temperatures increase the rate of recovery (Purcell, <xref rid="efs25357-bib-0132" ref-type="ref">1980</xref>). In the field, recovery happens more often when infections occur in the summer or autumn than during the spring (Feil and Purcell, <xref rid="efs25357-bib-0064" ref-type="ref">2001</xref>; Feil et al., <xref rid="efs25357-bib-0065" ref-type="ref">2003</xref>). It should be noted that winter recovery has been demonstrated for grapevines infected with <italic>X. fastidiosa</italic> subsp. <italic>fastidiosa</italic>, and that most of the research on the topic has been conducted in California. Winter recovery has also been shown for <italic>Prunus</italic> (Ledbetter et al., <xref rid="efs25357-bib-0100" ref-type="ref">2009</xref>)’ (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>). Nevertheless, the presence in the Washington DC area of trees chronically infected with isolates of <italic>X. fastidiosa</italic> subsp. <italic>multiplex</italic> highlights the fact that this bacterium can survive at higher latitudes. Henneberger et al. (<xref rid="efs25357-bib-0083" ref-type="ref">2004</xref>) pointed out also that the bacteria were able to overwinter in sycamore trees at relatively low air temperatures (−5°C), probably being protected in the roots. Similarly, <italic>X. fastidiosa</italic> is reported to survive severe winter conditions (−28°C) in almond in Iran. A key question is certainly how winter temperatures may affect establishment in northern Europe.</p></sec></sec><sec id="efs25357-sec-0049"><label>3.4.4</label><title>Spread</title><p><boxed-text position="anchor" content-type="box" id="efs25357-blkfxd-0006" orientation="portrait"><p><italic>Is the pest able to spread within the EU territory following establishment?

They have sucking mouthparts (mandibular and maxillary stylets) that allow them to reach the xylem of their host plants, from which they ingest sap and egest saliva. Owing to the very poor nutritional value of xylem fluid, xylem fluid feeders ingest large amounts of sap and produce large amounts of honeydew. They are generally not direct pests unless present at very high population levels. Within the Cicadomorpha, the three superfamilies, Cercopoidea, Cicadoidea and Membracoidea, include xylem fluid‐feeding groups but, whereas all Cercopoidea (known as spittlebugs or froghoppers) and Cicadoidea (cicadas) are regarded as xylem fluid feeders, the superfamily Membracoidea includes a single xylem fluid‐feeding subfamily, the Cicadellinae (known as sharpshooters). Only these three groups of “specialists” in xylem fluid feeding have been shown to be vectors of <italic>X. fastidiosa</italic>. Some phloem sap feeders also feed marginally to the xylem, however tests for <italic>X. fastidiosa</italic> transmission capacity on one of these species were negative (Purcell, <xref rid="efs25357-bib-0132" ref-type="ref">1980</xref>). Spittlebugs, cicadas and sharpshooters are heterometabolous insects that develop through egg, five nymphal stages and adult (winged) stage. Nymphs of cicadas and of spittlebugs of the family Cercopidae are subterranean root feeders, whereas nymphs of spittlebugs of the family Aphrophoridae and the subfamily of Cicadellinae develop on aboveground plant. All adults feed and live on the aerial parts of host plants (Ossiannilsson, <xref rid="efs25357-bib-0123" ref-type="ref">1981</xref>; Tremblay, <xref rid="efs25357-bib-0167" ref-type="ref">1995</xref>; Redak et al., <xref rid="efs25357-bib-0142" ref-type="ref">2004</xref>) (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>)’.</p><p>In Europe, only a few species of sharpshooters (Cicadellidae, subfamily Cicadellinae) are present (Wilson et al., <xref rid="efs25357-bib-0175" ref-type="ref">2009</xref>), although one species, <italic>Cicadella viridis</italic>, is widespread, common and locally abundant in humid areas. Differently, quite a high number of spittlebug species (Cercopoidea: Aphrophoridae and Cercopidae), are present (de Jong, <xref rid="efs25357-bib-0096" ref-type="ref">2013</xref>). Among these, the meadow spittlebug, <italic>Philaenus spumarius</italic> (Figure <xref rid="efs25357-fig-0007" ref-type="fig">7</xref>) is the most common species.

According to EFSA PLH Panel (<xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>), ‘Although it is expected that all sharpshooters and spittlebug species are vectors of <italic>X. fastidiosa</italic> (Frazier, <xref rid="efs25357-bib-0067" ref-type="ref">1944</xref>; Purcell, <xref rid="efs25357-bib-0133" ref-type="ref">1989</xref>; Almeida et al., <xref rid="efs25357-bib-0004" ref-type="ref">2005</xref>), it is important to demonstrate that species not formally identified as vectors can transmit the bacterium from plant to plant. In addition to identifying new vector species, studies should go further and provide information on the efficiency of the transmission process, so that the epidemiological relevance of newly identified species can be better put in context. This is important because, as previously demonstrated (Lopes et al., <xref rid="efs25357-bib-0106" ref-type="ref">2010</xref>; Daugherty et al., <xref rid="efs25357-bib-0038" ref-type="ref">2011</xref>), vector species may have very different transmission efficiencies depending on host plant species, or even by feeding on different tissues of the same host plant. Lastly, it is imperative to understand that detection of a pathogen within a putative vector is by no means evidence that a species is a vector; plant‐to‐plant transmission experiments are the only way to prove that a species is a vector’.</p><p>Furthermore, a positive transmission to a given test plant does not necessarily imply that the vector can transmit the pathogen to other plants known to be host.</p></sec><sec id="efs25357-sec-0053"><label>3.4.4.1.2</label><title>Geographical distribution and population abundance of European vectors and potential vectors</title><p>Although some species of spittlebugs and sharpshooters are ubiquitous and present in most, if not all, European countries, some others have a more restricted area of distribution or, due to their low population levels or to their narrow ecological niches, are known from only few countries/geographical areas. The xylem‐sap feeder <bold>species richness</bold> in European countries is summarised in Figure <xref rid="efs25357-fig-0006" ref-type="fig">6</xref>A, that only includes sharpshooters and spittlebugs, the two insect groups regarded as confirmed <italic>X. fastidiosa</italic> vectors, and in Figure <xref rid="efs25357-fig-0006" ref-type="fig">6</xref>B, which includes all the xylem‐sap feeder species (spittlebugs, sharpshooters, cicadas). It is clear that, wherever in Europe the bacterium is eventually present or introduced, indigenous xylem‐sap feeder insects are present and may act as vectors. Species richness of potential vectors, including cicadas is relatively homogenous over the EU, although the number of reported species of spittlebugs and sharpshooters is higher in Western, than Eastern Europe. The possibility that this difference in species number between western and eastern EU is due to less intense surveys for the presence of spittlebugs and sharpshooters in Eastern Europe cannot be excluded. When considering all the xylem‐sap feeders, including cicadas, species richness is higher in the Mediterranean area. However, due to the widespread presence of several species of potential vectors all over the EU, it is important to obtain information on the population level, rather than on the absolute number of species. Since xylem‐sap feeders were not regarded as a pest until the identification of <italic>X. fastidiosa</italic> in the EU, accurate estimates of population abundance of European spittlebugs are not available, although some data come from scattered field observations. <italic>Aphrophora salicina</italic> can be quite abundant on <italic>Salix cinerea</italic>, with up to one spittle mass (containing 2–8 nymphs) per two branchlets (Badmin, <xref rid="efs25357-bib-0010" ref-type="ref">2006</xref>). Both <italic>Aphrophora alni</italic> and <italic>A. salicina</italic> can be abundant on <italic>S. cordata</italic> (Czerniakowski, <xref rid="efs25357-bib-0037" ref-type="ref">2005</xref>). <italic>N. lineatus</italic> can be abundant on grasses (Novotny, <xref rid="efs25357-bib-0115" ref-type="ref">1987</xref>; Eyre et al., <xref rid="efs25357-bib-0060" ref-type="ref">2001</xref>), while <italic>N. campestris</italic> was relatively common, but not dominant, in the olive agroecosystems of Apulia (Ben Moussa et al., <xref rid="efs25357-bib-0012" ref-type="ref">2016</xref>). According to the literature, <italic>P. spumarius</italic> is clearly the dominant spittlebug species in Europe, in different geographical areas and in different ecosystems/crops, including the olive groves of Apulia (Saponari et al., <xref rid="efs25357-bib-0148" ref-type="ref">2014</xref>; Ben Moussa et al., <xref rid="efs25357-bib-0012" ref-type="ref">2016</xref>; Cornara et al., <xref rid="efs25357-bib-0033" ref-type="ref">2017</xref>), vineyards (Braccini and Pavan, <xref rid="efs25357-bib-0022" ref-type="ref">2000</xref>; Pavan, <xref rid="efs25357-bib-0125" ref-type="ref">2006</xref>; Kunz et al., <xref rid="efs25357-bib-0098" ref-type="ref">2010</xref>), grasslands (Eyre et al., <xref rid="efs25357-bib-0060" ref-type="ref">2001</xref>), and strawberry fields in Finland and Norway (Raatikainen and Vasarainen, <xref rid="efs25357-bib-0140" ref-type="ref">1970</xref>; Taksdal, <xref rid="efs25357-bib-0164" ref-type="ref">1977</xref>). Detailed data on population abundance of <italic>P. spumarius</italic> in Mediterranean olive groves of Northern and Southern Italy are in the study carried out in the frame of EFSA procurement on ‘Collection of data and information on biology and control of vectors of <italic>Xylella fastidiosa</italic>’. In this study, the site with the highest <italic>P. spumarius</italic> population had an average of 21 (with a peak of 49) nymphs per m<sup>2</sup> in 2016 and an average of 30 (with a peak of 68) nymphs per m<sup>2</sup> in 2017. In the same site, the adult population peaked at about 0.7–1.5 adults per sweep in the olive canopy (and at about 1.3–1.7 adults per sweep on other woody hosts) in 2016 and 2017, respectively. <italic>P. spumarius</italic> has a very wide distribution and, besides the Palearctic regions, it is also present in the Nearctic Region. In the United States, very high population densities of this species were reported in alfalfa and strawberry. Wiegert (<xref rid="efs25357-bib-0174" ref-type="ref">1964</xref>) observed peak densities of 1,280 nymphs/m<sup>2</sup> and 466 adults/m<sup>2</sup> in alfalfa fields of Michigan, while Zajac and Wilson (<xref rid="efs25357-bib-0180" ref-type="ref">1984</xref>) reported densities close to 1,000 nymphs/m<sup>2</sup> on strawberry. However, these population peaks were followed by steady decreases of the populations, likely due to the two concurrent factors, mortality and emigration.</p><p>Among European sharpshooters, <italic>Cicadella viridis</italic> is by far the most common and abundant species and, although few data on its population densities are available, it has been reported that in wet meadows with <italic>Juncus</italic> spp. and <italic>Holcus</italic> spp., densities of about 1,800 eggs and first instar nymphs and of almost 400 adults per m<sup>2</sup> can occur (Tay, <xref rid="efs25357-bib-0165" ref-type="ref">1972</xref>).

As for the spittlebugs, the most prominent biological feature, which can have important consequences for their role or potential role as <italic>X. fastidiosa</italic> vectors, is the association of nymphal stages with herbaceous plants, while the adults tend to colonise many different woody hosts, including <italic>Quercus</italic>,<italic> Salix</italic>,<italic> Ulmus, Betula</italic> and woody crops such as olive, grapevine, stone and pome fruits. <italic>Haematoloma dorsata</italic> and, to a lesser extent, <italic>Neophilaenus</italic> spp. adults feed on conifers. Host‐shifting behaviour is also well known for spittlebug adults that move from herbaceous to woody hosts soon after reaching adulthood and are back to herbaceous plants at the end of the season when they search for oviposition sites. <italic>P. spumarius</italic>, the meadow spittlebug, is a univoltine, highly polyphagous species that develops as nymph on many herbaceous dicotyledonous species (monocotyledonous are rarely exploited as host plants), mainly within the families Asteraceae and Fabaceae. Adults feed on herbaceous and woody hosts such as oak (evergreen and deciduous), myrtle, lentisk, almond, grapevine, olive, peach, etc. Females undergo an ovarian parapause and start maturing eggs only from late August onwards, depending on the latitude (Witsack, <xref rid="efs25357-bib-0176" ref-type="ref">1973</xref>; Cornara et al., <xref rid="efs25357-bib-0034" ref-type="ref">2018</xref>). The meadow spittlebug overwinters as eggs, laid on stubble, basal dry leaves, and the dead parts of plants; most of the eggs are laid close to the ground between two apposed surfaces (Cornara et al., <xref rid="efs25357-bib-0034" ref-type="ref">2018</xref>).

It has 1–3 generations per year, depending on the latitude and altitude (Frediani, <xref rid="efs25357-bib-0068" ref-type="ref">1955</xref>; Arzone, <xref rid="efs25357-bib-0009" ref-type="ref">1972</xref>; Tay, <xref rid="efs25357-bib-0165" ref-type="ref">1972</xref>; Pavan and Gambon, <xref rid="efs25357-bib-0126" ref-type="ref">2004</xref>).

A fecundity of about 35–60 eggs per female has been estimated for this species by Tay (<xref rid="efs25357-bib-0165" ref-type="ref">1972</xref>) and Arzone (<xref rid="efs25357-bib-0009" ref-type="ref">1972</xref>). According to Frediani (<xref rid="efs25357-bib-0068" ref-type="ref">1955</xref>), the fecundity is higher, at least 100 eggs per female.</p><p>As for flight activity and dispersal, little information is available for the European vectors and potential vectors. Although we know that both sharpshooters and spittlebug adults actively move to plants different from those hosting nymphs, no estimation of this active dispersal is available for European sharpshooters. In North America few authors provided estimates of <italic>P. spumarius</italic> dispersal capability. While nymphs can only move between neighbouring herbaceous plants, adults can fly, and be transported, over longer distances. Conflicting results on the dispersal capability of <italic>P. spumarius</italic> adults have been published. Halkka et al. (<xref rid="efs25357-bib-0080" ref-type="ref">1971</xref>) suggested that active flights were limited to 40–80 m, while Putman (<xref rid="efs25357-bib-0139" ref-type="ref">1953</xref>) noted massive long‐distance movements that could be interpreted as a migration phenomenon. It is worth noting that this latter paper simply describes visual observations and no measurements of dispersal were done. In Italy, some mark‐release‐recapture experiments are ongoing, and preliminary results indicate that spittlebugs were recaptured within a 100 m radius of the release points (Plazio et al., <xref rid="efs25357-bib-0129" ref-type="ref">2017</xref>).</p><fig fig-type="Figure" xml:lang="en" id="efs25357-fig-0007" orientation="portrait" position="float"><label>Figure 7</label><caption><p><italic>Philaenus spumarius</italic> at different life stages in Italy (A) Egg mass, (B) Nymph, (C) adult (pictures: courtesy of Vincenzo Cavalieri and Nicola Bodino, <styled-content style="fixed-case" toggle="no">IPSP</styled-content>‐<styled-content style="fixed-case" toggle="no">CNR</styled-content>)</p></caption><graphic id="nlm-graphic-13" xlink:href="EFS2-16-e05357-g007"></graphic></fig><p>The <italic>X. fastidiosa</italic> transmission ability is so far proven, both under field and laboratory conditions, only for <italic>P. spumarius</italic>.

The role of <italic>P. italosignus</italic> is probably negligible, as it has never been found in the infected demarcated area of Apulia and immatures are strictly associated with <italic>Asphodelus</italic> spp. <italic>N. campestris</italic> likely is of limited importance for the spread of <italic>X. fastidiosa</italic> in Apulia, because it has no preference for olives and therefore has little chance to acquire <italic>X. fastidiosa</italic> from and transmit it to olives. However, the presence of different vector species in different host plants and ecological niches can increase the range of <italic>X. fastidiosa</italic> natural reservoirs in the environment that, in their turn, can serve as a source of inoculum for the crops.</p><p>In Corsica, outbreaks of <italic>X. fastidiosa</italic> are associated with ST6 and ST7 and, although no transmission tests have been carried out yet, these STs were identified in insects and molecular analyses confirmed that an average of 20% of the <italic>P. spumarius</italic> specimens were contaminated (Cruaud et al., <xref rid="efs25357-bib-0036" ref-type="ref">2018</xref>). These findings strongly suggest the role of <italic>P. spumarius</italic> in the spread of these STs of <italic>X. fastidiosa</italic> subsp. <italic>multiplex</italic>, although the final evidence should come from transmission experiments. In Spain, a number of different STs has been identified in the Balearic Islands (belonging to the subspecies <italic>multiplex</italic>,<italic> fastidiosa</italic> and <italic>pauca</italic>) and in Alicante (ST6 of subspecies <italic>multiplex</italic>). However, so far no transmission tests have been done and preliminary data on <italic>X. fastidiosa</italic> genetic characterisation from <italic>P. spumarius</italic> and <italic>N. campestris</italic> collected in Alicante (see Section <xref rid="efs25357-sec-0035" ref-type="sec">3.2.2.3</xref> Current situation in Spain) confirm the presence of <italic>X. fastidiosa</italic> subsp. <italic>multiplex</italic> in this spittlebug species.</p><p>Characterisation of the sequence types detected in vectors is challenging, due to the very low number of bacterial cells in the insects that generally hamper successful MLST analyses (Cruaud et al., <xref rid="efs25357-bib-0036" ref-type="ref">2018</xref>; EPPO, <xref rid="efs25357-bib-0057" ref-type="ref">2018</xref>).

In Europe, the major role of spittlebugs has been emphasised (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>), because of the presence of few sharpshooter species and the wide distribution and abundance of spittlebugs, namely <italic>Philaenus</italic> and <italic>Neophilaenus</italic> spp. Transmission is rapid because there is no latency period. Therefore, the vector can transmit the bacterium immediately after acquisition. Moreover, the pathogen persists and multiplies in the foregut of the adult vectors, which can remain infectious throughout their lifespan (Almeida et al., <xref rid="efs25357-bib-0004" ref-type="ref">2005</xref>). Since the bacterium is lost with moulting and nymphs have a very limited mobility, only adults are regarded as being responsible for <italic>X. fastidiosa</italic> spread. The potential vector species in the EU are listed in Annex <xref rid="efs25357-sec-1003" ref-type="sec">C</xref> of the EFSA PLH Panel (<xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>).</p><p>Dispersal seems to be primarily limited by the short‐range flight of spittlebugs, whose active flights probably do not exceed a range of 100 m (Weaver and King, <xref rid="efs25357-bib-0172" ref-type="ref">1954</xref>; Halkka et al., <xref rid="efs25357-bib-0080" ref-type="ref">1971</xref>; Plazio et al., <xref rid="efs25357-bib-0129" ref-type="ref">2017</xref>). Although Putman (<xref rid="efs25357-bib-0139" ref-type="ref">1953</xref>) noticed ‘long‐distance flights’ in Ontario, no data were provided to support this statement and, so far, in Europe no migration phenomena have ben observed. The active dispersal of sharpshooters seems to be in the same range (Blackmer et al., <xref rid="efs25357-bib-0015" ref-type="ref">2004</xref>). Passive flights of spittlebugs through the wind are also possible (Wiegert, <xref rid="efs25357-bib-0174" ref-type="ref">1964</xref>; Halkka et al., <xref rid="efs25357-bib-0080" ref-type="ref">1971</xref>) and may allow for the dispersal of infected insects over longer distances. Finally, whose active flights it is worth noting that, according to EFSA PLH Panel (<xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>), the density and pattern of host plants in the landscape will have a significant influence on spread (Plantegenest et al., <xref rid="efs25357-bib-0128" ref-type="ref">2007</xref>), particularly on short‐ and medium‐range vector dispersal from plant to plant. In general, landscapes characterised by areas of contiguous hosts at high densities will be more conducive to spread. This concept has been applied to the case of ST53 strain of olive in the Apulia region (Strona et al., <xref rid="efs25357-bib-0161" ref-type="ref">2017</xref>), leading to the conclusion that <italic>X. fastidiosa</italic> will persist in the area. A mathematical model for the spread of this disease in Apulia has been produced (White et al., <xref rid="efs25357-bib-0173" ref-type="ref">2017</xref>) showing how the width of a control zone (established just outside the infected zone), together with the intensity of surveillance in this control zone, may delay the spread of the disease. According to Bosso et al. (<xref rid="efs25357-bib-0021" ref-type="ref">2016</xref>), the potential distribution under current condition comprises Portugal, Spain, Italy, Corsica, Albania, Montenegro, Greece and Turkey as well as all countries of northern Africa and the Middle East. <italic>X. fastidiosa</italic> is not predicted to change its distribution in the Mediterranean basin in response to climate change.</p></sec><sec id="efs25357-sec-0057"><label>3.4.4.3</label><title>Spread by human assistance</title><p>Transportation of infected plant material is generally an effective means of long‐distance dispersal (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>). Vegetative propagation through grafting is widely used for most long‐lived perennial <italic>X. fastidiosa</italic> hosts; transportation of live plant tissue is a common practice in the various agricultural industries affected by this pathogen, eventually increasing its geographic distribution (Almeida et al., <xref rid="efs25357-bib-0006" ref-type="ref">2014</xref>). Two factors are considered as important in the initial spread: (1) the long incubation period required for symptom expression and (2) the fact that the bacterium can be transmitted from plant material taken from infected but as yet asymptomatic plants used for grafting. The ban of marketing propagative material produced in the infected zones or the production of such a material under vector‐proof screen houses may limit this route of <italic>X. fastidiosa</italic> spread.</p><p>Inadvertent transportation of vectors in vehicles should also be considered, as this has been observed for <italic>P. spumarius</italic> in the infected area of Apulia (see Figure 12 in EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>) and is considered to be the cause of the Oria outbreak, approximately 30 km away from the infected area at that time (see Section <xref rid="efs25357-sec-0034" ref-type="sec">3.2.2.2</xref>.). Spread by vehicles may occur via the general public by car or by the transport of agricultural vehicles with infected plant material and vectors. Measures aimed at suppressing insect populations (e.g. mechanical removal of weeds and insecticide applications), required by Decision (EU) 2015/789, can effectively contribute to reduce the probability of hitchhiking infectious vectors, thus avoiding long‐distance spread of the pathogen.</p><p>In the currently affected zones of the risk assessment area, spread by human assistance could also be increased by commercial practices such as the direct retail selling of small potted cuttings and the important ferryboat traffic between Apulia and Greece, Corsica and mainland France and Italy, Balearic Islands and mainland Spain. However, the movement ban of specified plants out of any demarcated area and official checks required at the control measures taken in ferry ports aim at limiting such a risk.</p><p>Human‐assisted spread would result in stratified dispersal, with one long‐distance component allowing the colonisation of new areas; sometimes very far from the area of origin, followed by local colonisation of these newly reached spots by a diffusion process depending on autonomous local spread of the vectors (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>).</p><p>Since <italic>X. fastidiosa</italic> distribution in the EU is very likely the result of repeated and independent introductions, and the time of these introductions is debated, the only example of a ‘recent’ introduction followed by a clear and documented spread is the one of ST53 associated with the quick olive decline syndrome of olive in the Apulia region of Italy. In this area, following the identification of the pathogen in the autumn of 2013, regular and intensive surveys have been carried out up to now.

Thus, <italic>X. fastidiosa</italic> is considered to be a serious thread for agriculture, the environment and the economy (IPPC factsheet, <xref rid="efs25357-bib-0092" ref-type="ref">2017</xref>).</p><p>Historically, Pierce's disease caused by <italic>X. fastidiosa</italic> was responsible for an outbreak in California in the 1880s with the destruction of more than 16,000 ha of grapes (Goodwin and Purcell, <xref rid="efs25357-bib-0077" ref-type="ref">1997</xref>). Major outbreaks were also reported in the 1930s and 1940s. In 1999, the disease re‐emerged after the introduction of the glassy winged sharpshooter, <italic>H. vitripennis</italic>, and affected 25% of the 1,200 ha of vineyards in Riverside County, California (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>). According to Tumber et al. (<xref rid="efs25357-bib-0168" ref-type="ref">2014</xref>), federal, state and local governments and industry, together, spent nearly US$544 million dollars in the 1999–2010 period. The current annual cost of Pierce's disease in California is estimated around 104 million US$/year, in terms of disease prevention measures and vine losses (Blua et al., <xref rid="efs25357-bib-0017" ref-type="ref">1999</xref>).</p><p>Less recognised are the economic impacts of regions where susceptible crops could be grown if not for diseases caused by <italic>X. fastidiosa</italic>, for example grapes cannot be grown because of this pathogen in the southeastern states near the Gulf of Mexico.</p><p>Since its discovery in Brazil in 1987, it is estimated that citrus variegated chlorosis is responsible for the removal of more than 100 millions of citrus trees. The current annual cost of control measures is approximated around 120 million US$/year (IPPC, <xref rid="efs25357-bib-0092" ref-type="ref">2017</xref>). However, according to Fundecitrus, plant health management policies, which included among other measures the removal of infected trees, led to a better situation in recent years, with about 3.0% of infected plants in 2016 compared with 43.8% in 2004 (<ext-link ext-link-type="uri" xlink:href="http://www.fundecitrus.com.br/doencas/cvc/9">http://www.fundecitrus.com.br/doencas/cvc/9</ext-link>). The recent introduction in Apulia, Italy, has heavily impacted a large area of olive groves, the infected area exceeding 5,000 km<sup>2</sup> and including 1–3 millions of olive trees (Signorile, <xref rid="efs25357-bib-0157" ref-type="ref">2018</xref>). Luvisi et al. (<xref rid="efs25357-bib-0107" ref-type="ref">2017</xref>) estimated ca 115 € per dead olive tree while increase in management cost was assessed around 31%. Besides the agricultural and economic impact, olive quick decline disease also affected symbolic, centennial trees, considered of inestimable social, historical and cultural importance (IPPC, <xref rid="efs25357-bib-0092" ref-type="ref">2017</xref>). More importantly, the whole landscape has changed dramatically in just a few years, from one dominated by old, sometimes monumental trees, to another with dead trees that remind onlookers of what has been lost. The impact of changes to the landscape and ecosystem services is not easy to determine (Almeida, in preparation).</p><p>Ornamental plants are also affected. In the USA, oleander is planted along the sides of roads and in private gardens: losses on Californian highways alone have been estimated to amount to US$125 million (Henry et al., <xref rid="efs25357-bib-0084" ref-type="ref">1997</xref>). In the Mediterranean basin, oleander is used as ornamental plant but is also very common in the wild. In New Jersey, bacterial leaf scorch was estimated to affect 35% of the street and landscape oaks, with both aesthetic and economic consequences (Gould et al., <xref rid="efs25357-bib-0078" ref-type="ref">2004</xref>).

Efforts have been made towards public awareness of the disease and the risk of inadvertently moving plants from demarcated areas. ‘Strategies for preventing the spread from areas where the pathogen is present and for the control of an outbreak should focus on the two main pathways (plants for planting and infectious insects in plant consignments) and be based on an integrated system approach, combining, when applicable, the most effective options (e.g. removal of plants, control of vectors, establishment of pest‐free areas, intensive surveillance, certification, screen house production, testing for plant propagation material, preparation, treatment and inspection of consignments for the pathway of the infectious vectors in plant consignments’ (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>).</p><sec id="efs25357-sec-0063"><label>3.6.1.1</label><title>Biological or technical factors limiting the feasibility and effectiveness of measures to prevent the entry, establishment and spread of the pest</title><p>There are biological and technical factors that greatly limit the effectiveness of measures aimed at preventing entry, establishment and spread of <italic>X. fastidiosa</italic>. Among the most important ones are, the frequent asymptomatic association of the bacterium with the plant, the very wide range of host plant species and the ubiquitous presence of insect vectors and potential vectors in both the exporting and recipient countries. Moreover, considering the wide range of host plant species, there is a large trade volume of potentially infected plants. Finally, plants for planting material originate from numerous exporting countries where <italic>X. fastidiosa</italic> is present.</p></sec></sec><sec id="efs25357-sec-0064"><label>3.6.2</label><title>Pest control methods</title><p>There is no single control method for <italic>X. fastidiosa</italic>. Control should be implemented with regards to each specific situation, in an integrated manner and with an area‐wide management approach. Control methods were listed extensively in the previous EFSA risk assessment (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>). Besides the surveillance, eradication and containment measures already that are in place through the current emergency measures in place for all EU Member States, the currently used control methods are briefly listed below:

Following the introduction and spread of <italic>X. fastidiosa</italic> in the Apulian olive groves, at least two olive cultivars, Leccino and FS‐17, have shown traits of tolerance to the pathogen. The tolerance is expressed by significantly reduced symptoms development, when compared with highly sensitive cultivars (i.e. Ogliarola salentina and Cellina di Nardò) growing under a very high pressure of inoculum inside the infected zone, and by a lower amount of bacterial cells in infected tissues (Baù et al., <xref rid="efs25357-bib-0011" ref-type="ref">2017</xref>; Boscia et al., <xref rid="efs25357-bib-0019" ref-type="ref">2017a</xref>,<xref rid="efs25357-bib-0020" ref-type="ref">b</xref>; IPSP‐CNR technical report, <xref rid="efs25357-bib-0093" ref-type="ref">2017</xref>). Some of the genes putatively involved in the tolerant response to <italic>X. fastidiosa</italic> in the Leccino cultivar have been identified following a comparative transcriptomic analysis (Giampetruzzi et al., <xref rid="efs25357-bib-0071" ref-type="ref">2016</xref>), while others are currently under investigation (Saldarelli, personal communication). These findings, together with further studies aiming at investigating the molecular basis of the host response and pathways modulating different defence responses might open the possibility of breeding for resistance or tolerance.</p><p>Conventional breeding in California that produced wine grape varieties with strong resistance required decades to produce but the first grapes varieties resistant to <italic>X. fastidiosa</italic> subsp. <italic>fastidiosa</italic> are now being released (Walker and Tenscher, <xref rid="efs25357-bib-0170" ref-type="ref">2016</xref>; Walker et al., <xref rid="efs25357-bib-0171" ref-type="ref">2016</xref>).</p><p><bold>Plant removal</bold>. Roguing infected plants, and those surrounding them, that are likely in the incubation phase of the infection process, may be an effective control method as it suppresses the sources of inoculum for vectors in the environment (although the uncertainty is high due to the long incubation period). This measure may be more effective for reducing secondary spread (within the crop), as in olive groves in the Salento area, rather than primary spread due to incoming infected insects from outside the crop.</p><p>In a containment approach, where eradication is no longer feasible, severe pruning of infected, symptomatic plants has been indicated by some authors as a possible way to suppress disease symptoms in the plants (see EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>). Pruning of sweet orange trees in Brazil was reported to reduce the symptoms of citrus variegated chlorosis and eliminate infection, but only in very specific conditions at the very beginning of symptom development (Amaral et al., <xref rid="efs25357-bib-0007" ref-type="ref">1994</xref>), but this is the only case reported in literature (EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>). A recent paper (Daugherty et al., <xref rid="efs25357-bib-0039" ref-type="ref">2018</xref>) point out that severe pruning of infected grapevines has limited efficacy for managing Pierce's Disease. Severe pruning of infected olive trees has been applied within the infected area in Apulia, but this measure seems not preventing that disease symptoms re‐appear.</p><p><bold>Screen house production of plants for planting</bold> has been demonstrated to be very effective in the case of CVC and has been compulsory in Sao Paulo State of Brazil since 2003 (Gonçalves et al., <xref rid="efs25357-bib-0076" ref-type="ref">2011</xref>; EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>).</p><p><bold>Hot treatment of dormant plant material</bold> (see the opinions EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref> risk assessment and <ext-link ext-link-type="uri" xlink:href="https://efsa.onlinelibrary.wiley.com/doi/epdf/10.2903/j.efsa.2015.4225">https://efsa.onlinelibrary.wiley.com/doi/epdf/10.2903/j.efsa.2015.4225</ext-link> on <italic>Vitis</italic> sp. planting material and assessing its efficacy in the elimination of <italic>X</italic>. <italic>fastidiosa</italic></p><p><bold>Certification</bold> (see EFSA PLH Panel, <xref rid="efs25357-bib-0048" ref-type="ref">2015a</xref>; EPPO protocols, <xref rid="efs25357-bib-0057" ref-type="ref">2018</xref>)</p><p><bold>Control of insect vectors</bold> can be achieved by soil tilling in spring to kill the nymphs on the herbaceous plants (Regione Puglia, <xref rid="efs25357-bib-0143" ref-type="ref">2016</xref>) and by the application of insecticides on crops against the adults. Using both methods has a multiplier rather than additive effect and when combined with attempts to lower the percentage of insects infectious with <italic>X. fastidiosa</italic> can lower the number of infections by vectors.
