BACKGROUND Leishmaniases are a serious health problem in southeast Brazil, including the city of Belo Horizonte (BH), Minas Gerais state (MG), where there are high rates of incidence and mortality due to visceral leishmaniases. BH is divided into nine sanitary districts (SD) of which one, the Venda Nova SD, was selected for this study because it has high rates of positivity for canine leishmaniasis and high incidence of human leishmaniasis.OBJECTIVES This study aimed to survey the sand fly fauna in Venda Nova SD from August 2011 to July 2013 and perform a descriptive analysis of the vector population.METHODS The sampling was carried out using automatic HP light traps at all covered areas of the Venda Nova SD, in a total of eighteen light traps. Sampled specimens were identified following Galati (2003), and females were submitted to molecular techniques for the detection and identification of Leishmania DNA. A simple environmental description was done for it area and Kernel estimation was used to infer vector density for each study site.FINDINGS A total of 2,427 sand fly specimens belonging to eight species and five genera were collected of which 95.3% were Lutzomyia longipalpis. The seasonal variation curve was delineated by this species. Lu. longipalpis was the most abundant at all collection points and in all months of the study, and exhibited a natural infection rate of 1.01% for Leishmania infantum and 1.77% for Leishmania braziliensis.MAIN CONCLUSIONS The results show the presence and adaptation of Lu. longipalpis to the anthropic environment of BH and reinforces its role as the main vector of L. infantum in the region.

“…When comparing the number of specimens of each environment (intra, peridomicile, and forest) at the three settlements, we can notice that at anthropized environments (170/27%), a lower percentage of insects was observed when compared with the forest environment (460/73%); the higher quantity found in the forest can be explained by the plentiful organic matter of the soil and as this is the natural habitat of these insects 19 . Still, we should consider that it is usual at transmission areas of cutaneous leishmaniasis (CL) to have a destruction of primary forests with subsequent invasion of vectors into the peridomicile environment 20 .…”

Introduction: Leishmaniasis is expanding across Brazil, including the State of Mato Grosso (MT). The aim of this study was to characterize the phlebotomine sandfly fauna at three rural settlements located in the municipality of Cáceres, MT, from August 2010 to July 2011. Methods: Sandfly captures were conducted at the forest border and in intra and peridomicile areas with automatic light traps, biweekly, from 5pm to 6am. Results: Of the 630 sandflies collected, 348 were female, and 282 were male. Captured specimens were distributed across 11 genera -Brumptomyia, Evandromyia, Expapillata, Lutzomyia, Martinsmyia, Micropygomyia, Nyssomyia, Pintomyia, Psathyromyia, Psychodopygus, species. Among these, six species had not been marked yet in MT (Brumptomyia avellari, Br. mangabeirai, Evandromyia aldafalcaoae, Micropygomyia echinatopharynx, Micropygomyia peresi, and Pa. campograndensis). Nyssomyia whitmani was the most abundant species across ecotopes at all settlements. Interestingly, Lutzomyia longipalpis and Lutzomyia cruzi were found in sympatry. Conclusions: The disorganized occupation of the environment that is happening at the rural settlements of Mata Comprida, Laranjeira I and II could provide opportunities for the domiciliation of wild populations of phlebotomine, including vectors of leishmaniasis. Therefore, more studies are needed to understand the epidemiology of the disease in these areas and its impact on the human population. Keywords: Mato Grosso. Phlebotomine fauna. Nyssomyia whitmani. Rural settlement. RESUMO Introdução:As leishmanioses encontram-se em expansão no Brasil, inclusive no Estado de Mato Grosso (MT). A presente pesquisa teve como objetivo estudar a fauna flebotomínica em três assentamentos rurais localizados no município de Cáceres, MT, entre agosto de 2010 e julho de 2011. Métodos: As coletas foram realizadas na margem da mata, no intra e peridomicílio com armadilhas automáticas luminosas, quinzenalmente, das 17h às 6h. Resultados: Foram coletados 630 exemplares, sendo 348 fêmeas e 282 machos. Os espécimes foram distribuídos em 11 gêneros: Brumptomyia, Evandromyia, Expapillata, Lutzomyia, Martinsmyia, Micropygomyia, Nyssomyia, Pintomyia, Psathyromyia, Psychodopygus e Sciopemyia e 28 espécies, sendo que dentre estas, seis não haviam sido assinaladas em MT (Brumptomyia avellari, Br. mangabeirai, Evandromyia aldafalcaoae, Micropygomyia echinatopharynx, Micropygomyia peresi e Pa. campograndensis). Ressalta-se o encontro de Nyssomyia whitmani, espécie mais abundante nos diferentes ecótopos em todos os assentamentos. Destaca-se também a presença das espécies Lutzomyia longipalpis e Lutzomyia cruzi em simpatria. Conclusões: A ocupação desordenada do ambiente, como vem ocorrendo nos assentamentos Mata Comprida, Laranjeira I e II, pode proporcionar a domiciliação de populações selváticas de flebotomíneos, dentre estes os vetores das leishmanioses, tornando-se necessários maiores estudos para entender a dinâmica de transmissão dessas morbidades nestes locais.

SUMMARYThe Aquidauana municipality is considered an endemic area of leishmaniasis and an important tourist site in Mato Grosso do Sul State. The aim of this study was to investigate the sand fly fauna in the city of Aquidauana. Captures were carried out twice a month, from April 2012 to March 2014 with automatic light traps and active aspiration, in the peridomicile and domicile of six residences. A total of 9,338 specimens were collected, 3,179 and 6,159 using light traps and active aspiration, respectively. The fauna consisted of: Brumptomyia brumpti, Evandromyia aldafalcaoae, Ev. evandroi, Ev. lenti, Ev. orcyi, Ev. sallesi, Ev. termitophila, Ev. walkeri, Lutzomyia longipalpis and Psathyromyia bigeniculata. The most abundant species captured was Lutzomyia longipalpis, present in all the ecotopes, predominantly in peridomicile areas, and mainly males. Leishmania DNA was not detected in the insects. It was observed the abundance of the sand fly fauna in the region, as well as the high frequency of Lu. longipalpis, the main vector of L. infantum. The results of this study show the need to increase the monitoring and more effective control measures. It is noteworthy that the studied region presents several activities related to tourism and recreation, increasing the risk of transmission of leishmaniasis to this particular human population.
