“…This demonstrated the capacity of these species to adapt to houses, especially those located next to rain forest fragments. The location with the highest number of specimens caught was the peridomestic area, and this finding corroborates previous studies (BARATA et al, 2005;SILVA et al, 2010). It is important to highlight that in the present study, animal shelters (hen houses, stables and a piggery) were found in peridomestic areas, and their presence may have influenced the number of specimens collected.…”

Phlebotomines have worldwide distribution with many species present in Brazil, including the northeastern region, where the fauna is very diverse. The aim of this study was to identify the sandfly fauna in an area endemic for American cutaneous leishmaniasis (ACL) in the state of Pernambuco. Sandflies were caught on three consecutive nights every month from October 2015 to September 2016, from 5 pm to 5 am, using seven light traps of Centers for Disease Control (CDC) type. Females were identified and used for molecular Leishmania detection. A total of 2,174 specimens belonging to ten species were collected: Lutzomyia choti (88.2%; 1,917/2,174) was the most abundant species, followed by Lutzomyia whitmani (8.1%; 176/2,174) and Lutzomyia sordellii (1.5%; 33/2,174). The majority of the specimens were collected in peridomestic areas (64.1%; 1,394/2,174) and during the rainy period. All the samples examined were negative for Leishmania spp. The presence of Lutzomyia whitmani indoors and in peridomestic areas indicates that the inhabitants of this area are exposed to the risk of infection by the parasites responsible for ACL.Keywords: Lutzomyia, Leishmania, vectors. ResumoOs flebotomíneos apresentam uma ampla distribuição mundial com muitas espécies presentes no Brasil, inclusive na região Nordeste, onde a fauna é bastante rica. O objetivo desse estudo foi identificar a fauna de flebotomíneos em uma área endêmica para Leishmaniose Tegumentar Americana (LTA), no estado de Pernambuco. As capturas foram realizadas mensalmente, durante três noites consecutivas das 17h às 5h, utilizando sete armadilhas luminosas tipo CDC, no período de outubro de 2015 a setembro de 2016. As fêmeas identificadas foram utilizadas para análise molecular para detecção de Leishmania. Um total de 2.174 espécimes pertencentes a dez espécies foram coletadas: Lutzomyia choti (88,2%; 1.917/2.174) a espécie mais abundante, seguida por Lutzomyia whitmani (8,1%; 176/2.174) e Lutzomyia sordellii (1,5%; 33/2.174). A maioria dos espécimes foi coletada no peridomicílio (64,1%; 1.394/2.174) e no período chuvoso. Todas as amostras avaliadas foram negativas para Leishmania spp. A presença de Lutzomyia whitmani no intradomicílio e peridomicílio indica que a população residente nesta área está exposta ao risco de infecção por parasitos causadores de LTA.

“…The greater abundance and diversity of phlebotomine sandflies in the peridomicile has been observed in several areas of Brazil [11][12][13][14] . This behavior increases the risk of transmission of the leishmaniases, and it is related to the presence of animals in household surroundings, as well as vegetation and soil type, which might favor the establishment of breeding sites for phlebotomine sandflies 15 .…”

Introduction:In the last decades, a considerable geographic expansion of the leishmaniases in all regions of Brazil has been observed. The present study was carried out to identify the composition of the phlebotomine sandfly fauna and verify the seasonal variation of the main species after environmental changes occurred in São Vicente Férrer Municipality, State of Pernambuco, Brazil. Methods: Captures were carried out during four consecutive nights of each month using Centers for Disease Control and Prevention light traps from September 2009 to September 2010. The correlation between the number of phlebotomine sandflies captured and climatic factors (temperature and rainfall) was evaluated. Results: A total of 13,872 specimens belonging to 20 species were captured, of which, 6,247 (45%) were females, and 7,625 (55%) were males. Lutzomyia migonei was the most abundant species with 9,964 (71.8%) specimens, being predominant in the intradomicile and peridomicile areas with 108 (86.4%) and 9,746 (97%), respectively. In the forest remnants, Lutzomyia complexa 2,395 (65%) and Lutzomyia sordellii 770 (20.8%) predominated. The correlation analysis between the total number of sandflies captured and climatic factors did not show a significant influence on population density. Conclusions: The high abundance of Lutzomyia migonei and Lutzomyia complexa indicates the possibility of new cases of cutaneous leishmaniasis (CL). Keywords: Leishmaniases. Sandflies. São Vicente Férrer. RESUMO Introdução: Nas últimas décadas tem se observado uma considerável expansão geográfica das leishmanioses em todas as regiões do Brasil. O presente estudo foi realizado para identificar a fauna de flebotomíneos e verificar a sazonalidade das principais espécies após mudanças ambientais ocorridas no município de São Vicente Férrer, Estado de Pernambuco, Brasil. Métodos: As capturas foram realizadas durante quatro noites consecutivas por mês usando armadilhas luminosas CDC, no período de setembro de 2009 a setembro de 2010. A correlação entre o número de flebotomíneos capturados e fatores climáticos (temperatura e umidade) foi avaliada. Resultados: Foi capturado um total de 13.872 espécimes pertencentes a 20 espécies, sendo 6.247 (45%) fêmeas e 7.625 (55%) machos. Lutzomyia migonei foi a espécie mais abundante com 9.964 (71,8%) espécimes, sendo predominante no intradomicílio 108 (86,4%) e peridomicílio 9.746 (97%). Nos resquícios de mata primária, predominaram Lutzomyia complexa 2.395 (65%) e Lutzomyia sordellii 770 (20,8%). A análise de correlação entre o número total de flebotomíneos capturados e os fatores climáticos não mostrou uma influência significativa na densidade da população. Conclusões: A elevada abundância de Lutzomyia migonei e Lutzomyia complexa indica a possibilidade de novos casos de leishmaniose cutânea (LC). Palavras-chaves:Leishmanioses. Flebotomíneos.

“…Em relação a L. whitmani, estudos desenvolvidos em áreas de cerrado (REBÊLO et al, 1999;SILVA et al, 2010) e região amazônica também observaram a sua ocorrência na estação seca e chuvosa, contudo com percentual maior de espécimes capturados na estação chuvosa, diferindo, portanto, da presente observação.…”
