“…This species has been found in the mid-western region of the country in areas surrounding houses in the state of Mato Grosso do Sul and Goiás, mainly in domestic animal shelters [52–55]. A positive association between this species and cases of CL was observed in the state of Goiás [53]. Lutzomyia choti is a species with heterogeneous habitats and is present in both wild environments and areas surrounding houses.…”

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.

“…lenti was the most abundant species in the area, present in several environments studied and was shown to be highly attracted to Shannon traps. It has already been reported in pigsties, perches and savannah areas in MS (Galati et al 1996) and is also one of the most frequently found species in the urban peridomiciles of the capital, Campo Grande (Oliveira et al 2003), and in many other towns in the state of Goiás, where a significant association of this species with cases of ACL was observed (Martins et al 2002).…”

ResumoFlebotomíneos tem considerável importância na transmissão de agentes etiológicos de doenças tais como bartonelose, arboviroses e especialmente a leishmaniose visceral e leishmaniose tegumentar americana, enfermidades presentes na cidade de Goiás. Com o objetivo de se identificar a população de flebotomíneos nesta localidade, foram realizadas capturas desses insetos na área urbana da cidade de Goiás. As armadilhas CDC foram posicionadas ao longo de toda área urbana, entre setembro de 2012 e agosto de 2013, no último final de semana de cada mês, repetidamente por três noites seguidas. Além da captura de insetos, foram coletados dados de umidade, precipitação e temperatura. Os resultados obtidos foram analisados por meio de estatística descritiva e analisados pela correlação AbstractPhlebotomine sandflies have considerable importance in the transmission of the etiological agents of diseases, such as bartonellosis, arboviruses, and especially visceral and cutaneous leishmaniasis, diseases present in the city of Goiás. In order to know the population of sand flies in this locality, collections of these insects have been taken in the urban area of the city of Goiás. CDC traps were placed throughout the urban area between September 2012 and August 2013, in the last weekend of each month, for three consecutive nights. In addition to capturing insects, we collected humidity, precipitation and temperature data. The results obtained through Pearson test showed a weak relationship between the amount of gathered sand flies with humidity. A total of 342 sand flies were collected, belonging to eight species: Lutzomyia longipalpis, Nyssomyia whitmani, Nyssomyia intermedia, Evandromyia lenti, Psathyromyia shannoni, Micropygomyia peresi, Evandromyia bacula and Micropygomyia goiana. This is the first record of Ev. bacula, Mi. peresi and Mi. goiana to the city of Goiás.
