“…whitmani was present in lower percentages at peridomicile environments (25.8%); however, it is worth noticing that this vector is opportunistic and has an eclectic habit for food, adjusting its eating habits to the availability of hosts at anthropic environments 37 . According to Souza et al 38 , transmission of leishmaniasis can occur in intradomicile and peridomicile environments.…”

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.

“…Among these, L. whitmani, L. yuilli yuilli, and L. flaviscutellata are species known to have a high capacity to adapt to and reproduce in urban environments (29) (50) . This adaptation is most likely related to the flexible eating habits of these species, which feed on any available host in modified environments (51) . Conversely, L. flaviscutellata feeds on wild rodents, which circulate among all of the different ecotypes studied, facilitating the adaptation of these insects in non-forest areas (49) .…”

Introduction: Understanding the diversity of sand flies is important for the epidemiology and control of leishmaniasis. This study aimed to understand the frequency, diversity, and seasonality of medically important sand flies in the municipality of Sinop, State of Mato Grosso, Brazil. Methods: The study was conducted in an urban area, including four ecotypes with different levels of urbanization. The sand flies were collected using light traps for three nights per month, from May 2014 to April 2015. Results: A total of 62,745 sand flies was collected, 52.34% of which were female. The frequency and diversity of sand flies was the highest in areas of permanent preservation (APPs) (96.85%), and was lower in more urbanized areas. Lutzomyia dasypodogeton was the most frequent species in the APPs. Lutzomyia antunesi was the most frequent in neighborhoods with forest fragments and neighborhoods around APPs, and L. aragaoi was the most frequent in completely urbanized neighborhoods. A higher frequency and diversity of sand flies was observed in the rainy season (87.92%) than in the dry season (12.08%). Eight medically important species were captured, and Lutzomyia antunesi, which is associated with American cutaneous leishmaniasis and visceral leishmaniasis, was observed in all ecotypes throughout the year. Conclusions: We observed a high frequency and diversity of sand flies in all urban areas, and some species collected were major vectors of leishmaniasis. These results support the need for further studies of the natural rates of infection of these insects and the circulation of the disease in hosts and vectors.
