Abstract

Stratification studies showed that the vast majority of sand fly species in the Manaus region are found in tree canopies (15m), and that there are two dominant species which are the vectors of Leishmania braziliensis guyanensis. It took 43 weeks of trapping to capture all 50 species of sand flies collected.

Resumo

Estudos de estratificação mostram que a maioria das espécies de flebótomos, na região de Manaus é encontrada na copa da floresta, espécies das quais duas são dominantes, funcionando como vetores de Leishmania braziliensis guyanensis. Gastaram-se 43 semanas de capturas para coletar todas as 50 espécies encontradas e é de supor-se existir uma população de flebótomos por espécie na floresta.
