Phlebotomine sand flies (Psychodidae: Phlebotominae) in an area of canine infection caused by Leishmania infantum in the state of Amapá, eastern Amazon

Flebotomíneos (Psychodidae: Phlebotominae) em área de infecção canina por Leishmania infantum no estado do Amapá, Amazônia Oriental

Abstract

In 2017, the Brazilian State of Amapá registered the first occurrence of visceral leishmaniosis (VL) in 17 dogs in the outskirts of the capital, Macapá. Given the lack of knowledge on phlebotomines in that area, this study aimed to survey the fauna of these Diptera. Sampling was performed using CDC light traps placed at ten sampling sites. The specimens captured were Evandromyia walkeri (n=237), Nyssomyia antunesi (n=65) and Bichromomyia flaviscutellata (n=6). The phlebotomine species composition resulted in low species diversity, and none of the main vectors of the etiological agent of VL were identified in the study area.
