Resumo: Introduction: In recent years, visceral leishmaniasis, a major public health problem, has been spreading from the rural to urban areas in many areas of Brazil, including Aracaju, the capital of the State of Sergipe. However, there are no studies of the sandfly fauna in this municipality or its variation over the year. Methods: Phlebotomine sandflies were collected from a rural area of Aracaju from September 2007 to July 2009. Modified CDC ultra-violet (UV) light traps were used to evaluate sandfly monthly distribution and their presence in the domestic and peridomestic environments. Results: The most abundant species was Lutzomyia longipalpis (90.4%) followed by Evandromyia lenti (9.6%). A chicken shed trap site had the highest proportion of L. longipalpis (51.1%) and large numbers of L. longipalpis were also collected in the houses closest to the chicken shed. There was a positive correlation between monthly rainfall and L. longipalpis abundance. Conclusions: Lutzomyia longipalpis is the most abundant species and is probably the main vector of the visceral leishmaniasis agent in the rural area of Aracaju. An increase in L. longipalpis frequency was observed during the rainy season. The peridomicile-intradomicile observations corroborate the importance of chicken sheds for the presence of L. longipalpis in the peridomestic environment. The great numbers of L. longipalpis inside the houses confirm the endophilic behaviour of this species and the possibility of visceral transmission in the intradomicile.

No entanto, não existem estudos sobre a fauna de flebotomíneos presente nesse município ou de sua distribuição ao longo do ano. MÉTODOS: As coletas de flebotomíneos foram realizadas em uma área rural de Aracaju, capital do Estado de Sergipe no periodo de setembro de 2007 a julho de 2009. Armadilhas CDC modificadas acopladas com luz ultravioleta (UV) foram utilizadas para avaliar a distribuição mensal e a presença de flebotomíneos nos ambientes doméstico e peridoméstico. RESULTADOS: Lutzomyia longipalpis foi a espécie mais abundante (90,4%), seguida por Evandromyia lenti (9,6%). Os locais com as maiores quantidades de L. longipalpis (51,1%) foram um galinheiro e as casas mais próximas a ele. Houve uma correlação positiva entre a precipitação mensal e a abundância de L. longipalpis. CONCLUSÕES: Lutzomyia longipalpis é a espécie mais abundante e, provavelmente, o principal vetor do agente da leishmaniose visceral na área rural de Aracaju. Foi observado um aumento na frequência de L. longipalpis nos meses chuvosos. As coletas realizadas no ambiente externo e interno dos domicílios reforçam a relevância dos galinheiros para a presença de L. longipalpis no ambiente peridoméstico. O grande número de L. longipalpis dentro das casas confirma o comportamento endofílico dessa espécie e a possibilidade de transmissão intradomiciliar da leishmaniose visceral.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Inst Tecnol & Pesquisa Sergipe, Lab Doencas Infecciosas & Parasitarias, Aracaju, SE, BrazilSecretaria Estado Saúde Estado Sergipe, Aracaju, SE, BrazilSecretaria Saúde Estado São Paulo, Lab Mogi Guacu, São Paulo, BrazilUniv Fed Sergipe, Dept Biol, Aracaju, SE, BrazilFundação Oswaldo Cruz, Ctr Pesquisas Aggeu Magalhaes, Recife, PE, BrazilUniv Estadual Julio de Mesquita Filho, Fac Ciencias Farmaceut, Araraquara, SP, BrazilUniv Estadual Julio de Mesquita Filho, Fac Ciencias Farmaceut, Araraquara, SP, BrazilCNPq: 410481-2006/08Soc Brasileira Medicina TropicalInst Tecnol & Pesquisa SergipeSecretaria Estado Saúde Estado SergipeSecretaria Saúde Estado São PauloUniversidade Federal de Sergipe (UFS)Fundação Oswaldo CruzUniversidade Estadual Paulista (Unesp)Sierpe Jeraldo, Veronica de Lourdesde Oliveira Goes, Marco AurelioCasanova, ClaudiodeMelo, Claudia Mourade Araujo, Edilson DivinoBrandao, Sinval PintoRocha Cruz, Danilo EsdrasPinto, Mara Cristina [UNESP]2014-05-20T13:24:17Z2014-05-20T13:24:17Z2012-05-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article318-322application/pdfhttp://dx.doi.org/10.1590/S0037-86822012000300008Revista da Sociedade Brasileira de Medicina Tropical.
