“…Por outro lado, algumas espécies poderiam estar em fase inicial de adaptação ao ambiente peridoméstico. Tais espécies, ainda que aparentemente raras (Tabela 1) e sem importância conhecida na epidemiologia das leishmanioses, seriam passíveis de adaptação e de virem a desempenhar funções vetoriais 32 .…”

RESUMOEste estudo descreve comunidades de flebotomíneos e suas variações sazonais em focos de transmissão das leishmanioses na interface urbano-rural do município minerário de Juruti, Estado do Pará, na Região Amazônica. Realizou-se captura mensal de flebotomíneos durante dois anos, em duas localidades sentinelas, Santa Maria e Paraense. Armadilhas CDC foram colocadas no intra e no peridomicílio. A amostra de 36.408 flebotomíneos teve 32 espécies representadas; as mais frequentes foram Lutzomyia longipalpis (76,8%) e Lutzomyia walkeri (19%). A riqueza de espécies foi maior em Paraense, a despeito da destacada abundância de Lu. longipalpis (85%, 23.878/27.951), sobretudo no inverno amazônico (r = 0,8; p < 0,05). Em Santa Maria, Lu. longipalpis, pouco frequente, não apresentou variação sazonal. Constatou-se a ocorrência, apenas em Paraense, no interior de residências, de flebotomíneos naturalmente infectados por Leishmania sp.: Lu. longipalpis (0,12%; 1/821), vetor de Leishmania (Leishmania) infantum; e Lutzomyia antunesi (1,16%; 2/173), provável vetor de Leishmania (Viannia) lindenbergi. A alta frequência de Lu. longipalpis no período chuvoso, mas apenas em Paraense, revela influências locais determinantes da composição da comunidade de flebotomíneos e abundância de espécies. Ações integradas para a prevenção das leishmanioses devem ser contínuas e preferencialmente intensificadas de setembro a novembro, meses que antecedem as chuvas naquela região.Palavras-chave: Leishmaniose; Região Amazônica; Psychodidae; Insetos Vetores; Ecologia. ARTIGO ORIGINAL | ORIGINAL ARTICLE ABSTRACTThis study describes the phlebotomine communities and their seasonal variation in areas of leishmaniasis transmission in the urban-rural interface of the mining municipality of Juruti, Pará State, in the Amazon Region. Monthly captures of phlebotomine sand flies were performed over two years in two sentinel locations: Santa Maria and Paraense. CDC traps were placed on intra and peridomestic environments. A sample of 36,408 phlebotomine sand flies contained 32 species. The most frequent were Lutzomyia longipalpis (76.8%) and Lutzomyia walkeri (19%). Species richness was greater in Paraense, despite the abundant presence of Lu. longipalpis (85%, 23,878/27,951), especially during the Amazonian winter (r = 0.8; p < 0.05). In Santa Maria, the presence of Lu. longipalpis, which occurs rarely, showed no seasonal variation. In the interior of residences, exclusively in Paraense, there was also the occurrence of phlebotomine sand flies naturally infected by Leishmania sp.: Lu. longipalpis (0.12%; 1/821), vector of Leishmania (Leishmania) infantum and Lutzomyia antunesi (1.16%; 2/173), most likely the vector of Leishmania (Viannia) lindenbergi. The high frequency of Lu. longipalpis during the rainy season, but only in Paraense, reveals local influences that determine the phlebotomine community composition and the abundance of species. Integrated actions for the prevention of leishmaniasis must be continuous and preferably intensified from September t...

“…In this environment 72 species are found, corresponding to 79.1% of the fauna (Rebêlo et al 2001a, 2001b, Marinho et al 2008, Azevedo et al 2011). In areas where vegetation is more open with the presence of cerrado and a semi‐humid climate, the diversity is less, but even so, 45 species have been found, representing 49.5% of the state fauna (Rebêlo et al 2010, Martins et al 2011, Silva et al 2015).…”

The richness and abundance of sand fly species were studied in northeastern Brazil in areas of leishmaniasis transmission. The study was carried out in two forest areas with different deforestation times for agricultural and livestock activities: one modified by long‐term settlement (more than 50 years of occupation) and another less impacted by short‐term settlement (10 years). The sand flies were captured with CDC light traps from 18:00 to 06:00 for three consecutive nights, once a month, from May, 2012 to April, 2014. The study captured 21,708 specimens and also 33 species of Lutzomyia and two of Brumptomyia. Species richness and abundance were higher in the more conserved area of short‐term occupation (31 species; 61.7%) than in the more degraded area with long‐term occupation (17 species; 38.3%). In the most conserved area, the species richness was higher in the forest fragment than in the rural settlement, whereas in the degraded area the richness was higher in the peri‐domicile than in the forest. The diversity was higher in the degraded area forest. There were significant statistical differences when comparing the means of total abundance with the intra‐domicile, peri‐domicile, and forest environments. The average abundance was statistically higher in the peri‐domicile compared to the forest (p = 0.009), but there were no statistically significant differences between intra‐domicile‐peri‐domicile (p = 0.11) and forest‐intra‐domicile (p = 0.87). In conclusion, a change in vegetation cover negatively affects the richness and abundance of sand flies in the natural environment.
