Sand flies are often collected in urban areas, which has several implications for the risk of transmission of LeishmaniaRoss, 1903, to humans and other mammals. Given this scenario, we describe the sand fly fauna of caves and their surroundings in Mangabeiras Municipal Park (MMP) and Paredão Serra do Curral Park (PSCP), both located in the urban area of Belo Horizonte, Minas Gerais, Brazil, an endemic focus of visceral and cutaneous leishmaniasis. Collections were conducted monthly from November 2011 to October 2012, using CDC light traps exposed for two consecutive nights in four caves and their surroundings. Nonsystematized collections using Shannon traps and active searches were also performed around the caves. The presence of LeishmaniaDNA in collected female sand flies was evaluated by ITS1-PCR. A total of 857 sand flies representing fourteen species were collected in MMP, of which Evandromyia edwardsi(Mangabeira, 1941) was the most abundant. Leishmania amazonensiswas detected in Brumptomyia nitzulescui(Costa Lima, 1932) and Ev. edwardsi,with the latter also having Leishmania braziliensis, Leishmania infantum,and Leishmaniasp. A total of 228 sand flies representing four species were collected in PSCP, of which Sciopemyia microps(Mangabeira, 1942) was the most abundant. No females from PSCP were positive for Leishmania-DNA. Studies aimed at describing sand fly faunas of cave environments and detecting Leishmaniaare essential to understanding the relationship between these insects and this ecotope and assessing and monitoring areas that may pose risks to the health of visitors and employees. |
