Abstract
Phlebotomine sandflies are vectors of important pathogens world-wide, including Leishmania spp. in the Neotropics. Entomoparasites have been described from phlebotomines, including virus, bacteria, protozoa, fungi, nematodes, and mites, some of which are capable of killing the host. In the present study, interference, fluorescence, and scanning electron microscopies were used for the first time to detect and morphologically characterize a new entomoparasite infecting Lutzomyia longipalpis. Several filiform larvae and eggs in different stages were encountered in the abdomen of female and male insects. Pairs of large egg-bearing nematodes found within cyst-like structures or free in the hemocel accompanied by larvae could be the adult sexual stages. This entomoparasite infects sand flies naturally in the field. We believe that stress caused by the colonization procedure produced an increase in the infection rate among sand flies affecting their development. These findings could be applied to future biological control studies of sand fly vectors.

<EA>Phlebotomine sandflies are vectors of important pathogens world-wide, including Leishmania spp. in the Neotropics. Entomoparasites have been described from phlebotomines, including virus, bacteria, protozoa, fungi, nematodes, and mites, some of which are capable of killing the host. In the present study, interference, fluorescence, and scanning electron microscopies were used for the first time to detect and morphologically characterize a new entomoparasite infecting Lutzomyia longipalpis. Several filiform larvae and eggs in different stages were encountered in the abdomen of female and male insects. Pairs of large egg-bearing nematodes found within cyst-like structures or free in the hemocel accompanied by larvae could be the adult sexual stages. This entomoparasite infects sand flies naturally in the field. We believe that stress caused by the colonization procedure produced an increase in the infection rate among sand flies affecting their development. These findings could be applied to future biological control studies of sand fly vectors.</EA>
