Resumo
The geographical distribution of leishmaniasis has undoubtedly expanded, and is now being reported to be
in areas that were previously non-endemic. This study therefore aimed to investigate whether there is any variation in
the structure and in the composition of phlebotomine communities along an environmental gradient - from a mesic to
a xeric environment, across different climatic periods (rainy and dry seasons). Furthermore, we test whether there were
differences in sex ratio of sand flies between wet and dry environments. A total of 535 specimens of sand flies belonging
to 18 species were recorded. Richness, abundance, and composition of species were significatively higher in the xeric
environment (semidecidual Forest) compared to the mesic environment (Riparina Forest). We unveiled site specific
differences in sand fly collections since the community composition changes with the geographic distance among the
sampling points. These results led to the conclusion that for sand flies species, the environmental conditions available
for each species could be different within the habitat taking into account the degree of humidity in the forest as well
as the climatic season (dry or wet). The present study gives a valuable contribution to the knowledge of sand flies, as
a group of insects, from the Atlantic Forest biome.
