Leishmaniasis vectors in Morro do Diabo State Park (PEMD), Teodoro Sampaio - SP, Brazil

Abstract

The aim of this study was to evaluate the similarity, dominance and diversity of phlebotomine communities in the interior and edges of the Morro do Diabo State Park (PEMD). This work was carried out through nocturnal collections of sand flies, using Shannon and CDC traps. The data were analysed by PAST and DivEs software. Four different species of sand flies were found inside the PEMD, with 190 specimens of Nyssomyia neivai, 128 of Pintomyia pessoai, 04 Evandromyia carmelinoi and 02 Nissomyia whitmani. At the edge of the park, five different species were found, including 1620 specimens of Nyssomyia neiva, 12 of Nissomyia whitmani, 04 of Evandromyia lenti, 01 of Psathyromyia aragaoi and 01 of Brumptomyia brumpti. Based on these data, the index of similarity between sandfly communities in the interior and edge of the park was 0.44, the dominance index was 0.50 and the diversity, with a significant difference, was 0.015. The obtained and calculated parameters were important to understand the similarity and dominance among the phlebotomine communities of the park, highlighting the low similarity between the different communities and revealing no species dominance. A significant difference in species diversity was found between samples.
