“…Moreover, the vector role of L. migonei has been suggested in areas of autochthonous cases of VL where L. longipalpis, the classic vector of Leishmania (Leishmania) infantum, is not found 6,22,23 . Lutzomyia complexa, the predominant species in forest remnants, which presents considerable distribution in Pernambuco, also has been reported in Recife, Paudalho (northern rainforest area) and Amaraji (southern rainforest area) 24 . The current study corroborates the data presented by Brandão-Filho et al 25 that reported the preference of this species for forested environments and its relationship with the enzootic cycle of CL.…”

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.

Cutaneous leishmaniasis (CL) is caused by a protozoan of the genus Leishmania and is transmitted by sand flies. The state of Espírito Santo (ES), an endemic area in southeast Brazil, has shown a considerably high prevalence in recent decades. Environmental niche modelling (ENM) is a useful tool for predicting potential disease risk. In this study, ENM was applied to sand fly species and CL cases in ES to identify the principal vector and risk areas of the disease. Sand flies were collected in 466 rural localities between 1997 and 2013 using active and passive capture. Insects were identified to the species level, and the localities were georeferenced. Twenty-one bioclimatic variables were selected from WorldClim. Maxent was used to construct models projecting the potential distribution for five Lutzomyia species and CL cases. ENMTools was used to overlap the species and the CL case models. The Kruskal–Wallis test was performed, adopting a 5% significance level. Approximately 250,000 specimens were captured, belonging to 43 species. The area under the curve (AUC) was considered acceptable for all models. The slope was considered relevant to the construction of the models for all the species identified. The overlay test identified Lutzomyia intermedia as the main vector of CL in southeast Brazil. ENM tools enable an analysis of the association among environmental variables, vector distributions and CL cases, which can be used to support epidemiologic and entomological vigilance actions to control the expansion of CL in vulnerable areas.
