Ecology and spatial distribution of sand fly species in low endemic areas for American Tegumentary Leishmaniasis in the municipality of Seropédica, Rio de Janeiro, Brazil.

Due to the fundamental role that sand flies (Diptera: Psychodidae) have in Leishmania spp. (Kinetoplastida: Trypanosomatidae) transmission, the objective of this study was to evaluate the ecology and spatial distribution of species circulating in the municipality of Seropédica, Rio de Janeiro, Brazil. A total of 17 371 specimens were collected between August 2016 and July 2017, and five species were identified: Nyssomyia intermedia (Lutz & Neiva, 1912), Migonemyia migonei (França, 1920), Nyssomyia whitmani (Antunes & Coutinho, 1939), Pintomyia pessoai (Coutinho & Barretto, 1940), and Pintomyia fischeri (Pinto, 1926). In relation to the number of sand flies collected, we observed a significant difference between rural and periurban areas and between the neighbourhoods. We observed that N. intermedia has a relatively greater adaptation to the peridomiciliary environment. This is the first report of Pi. pessoai and Pi. fischeri (only females) in Seropédica as well as the first record of the frequency of phlebotomine species focusing on some ecological indices and the spatial distribution of sand flies. The results presented here aimed to provide an insight into the spatial population dynamics of phlebotomine species in low endemic areas of American Tegumentary Leishmaniasis (ATL) in Seropédica, highlighting important areas for entomological surveillance.
