Diversity and natural infection of phlebotomine sand flies (Diptera, Psychodidae) in an endemic area of American tegumentary leishmaniasis in southeastern Bahia, Brazil.

ABSTRACT:

Background

The Cacao Region spans several municipalities in the state of Bahia. It is one of the major foci of American tegumentary leishmaniasis (ATL) in Brazil. We report the findings of a pilot cross-sectional study describing the phlebotomine fauna found around living sites of newly diagnosed ATL cases in that area.

Methods

The sand fly fauna was studied from May 2018 to June 2019 via an entomological survey, as recommended by the Brazilian Ministry of Health.

Results

Six hundred nineteen phlebotomine sand flies of 20 species were captured: 272 males (44%) and 347 females (56%). Nyssomyia whitmani was the most prevalent (62.2%), followed by Nyssomyia intermedia (9.2%), Evandromyia bahiensis (6.3%), endemic to Bahia, and Trichophoromyia viannamartinsi (4.5%). Ninet
