Abstract
- SUMMARY The aim of this study was to identify blood meals of female sandflies captured in the municipality of Governador Valadares, an endemic area of visceral and cutaneous leishmaniasis, in the State of Minas Gerais, Brazil. From May 2011 to January 2012, captures were performed using HP light traps in four districts. There were 2,614 specimens (2,090 males and 524 females) captured; 97 engorged females were identified belonging to the species Lutzomyia longipalpis (82.1%) and Lutzomyia cortelezzii (17.9%). Considering simple and mixed feeding, the enzyme-linked immunosorbent assay revealed a predominance of chicken blood (43.6%) in Lutzomyia longipalpis, showing the important role that chickens exert around the residential areas of Governador Valadares. This finding increases the chances of sandflies contact with other vertebrates and consequently the risk of leishmaniasis transmission. RESUMO O objetivo deste estudo foi identificar o repasto sanguíneo de fêmeas de flebotomíneos capturadas no município de Governador Valadares, área endêmica de leishmaniose visceral e tegumentar no Estado de Minas Gerais, Brasil. Entre maio de 2011 e janeiro 2012 foram realizadas capturas com armadilhas luminosas HP em quatro bairros. Foram capturados 2.614 exemplares (2.090 machos e 524 fêmeas). Noventa e sete fêmeas ingurgitadas foram identificadas como pertencentes às espécies Lutzomyia longipalpis(82,1%) e Lutzomyia cortelezzii(17,9%). Considerando a alimentação simples e a mista, o ensaio imunoenzimático revelou em Lutzomyia longipalpisuma predominância de sangue de galinhas (43,6%), mostrando o importante papel que galinhas podem exercer no peridomicílio, aumentando a chance de contato dos flebotomíneos com outros vertebrados e, consequentemente, o risco de transmissão da leishmaniose.
