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.

“…Phlebotomine sandflies (Diptera: Psychodidae: Phlebotominae) are insects with worldwide distribution, been described until now 989 species (ALMEIDA et al, 2015). These insects are vectors of numerous pathogens with some species transmitting protozoa of the genus Leishmania Ross (Kinetoplastida, Trypanosomatidae), i.e.…”

This study had the aim of ascertaining the sandfly fauna and possible presence of Leishmania in these insects, collected in caves in the state of Rondônia, Brazil. Collections were conducted in eight caves located in two different areas of this state. Leishmania in the sandflies collected was detected using the polymerase chain reaction (PCR). This was the first study on sandflies from caves in Rondônia and, among the total of 1,236 individuals collected, 24 species and 10 genera were identified. The species Evandromyia georgii was collected for the first time in Rondônia and the most abundant species were Trichophoromyia ubiquitalis with 448 individuals (36.2%), followed by T. octavioi with 283 (22.9%) and E. georgii with 179 (14.5%). For the PCR, 17 pools were analyzed and five pools were positive (for T. auraensis in three pools and for Nyssomyia shawi and N. antunesi in one pool each). The kDNA region was amplified and the presence of Leishmania DNA was confirmed. The sandfly fauna in these caves can be considered diverse in comparison with similar studies in other regions. It may be that some species use caves as a temporary shelter and breeding site, while other species live exclusively in this environment. The detection of Leishmania DNA indicates that this pathogen is circulating in cave environments and that further studies are needed in order to ascertain the risks of infection by leishmaniasis in these locations with high touristic potential.Keywords: Caves, sandflies, Rondônia, Amazon. ResumoO objetivo deste estudo foi conhecer a fauna de flebotomíneos, e possível presença de Leishmania nestes insetos, coletados em cavernas do Estado de Rondônia. As coletas foram realizadas em oito cavernas localizadas em duas áreas diferentes do Estado. A detecção de Leishmania nos flebotomíneos foi realizada por reação em cadeia da polimerase (PCR). Este foi o primeiro trabalho com flebotomíneos em cavernas de Rondônia e um total de 1,236 indivíduos foram coletados e identificados em 24 espécies e 10 gêneros. Evandromyia georgii foi coletada pela primeira vez em Rondônia, e as espécies mais abundantes foram Trichophoromyia ubiquitalis com 448 indivíduos (36.2%) seguida por T. octavioi com 283 (22.9%) e E. georgii com 179 (14.5%). No estudo de PCR, 17 pools foram analisados, sendo cinco positivos (T. auraensis -3, Nyssomyia shawi e N. antunesi -1 cada). A região do kDNA foi amplificada confirmando a presença de DNA de Leishmania. A fauna de flebotomíneos nestas cavernas foi considerada diversa quando comparada com estudos semelhantes de outras regiões. É possível que algumas espécies utilizem cavernas como abrigo temporário e local de procriação e outras sejam exclusivas deste ambiente. A detecção de DNA de Leishmania indica que este patógeno está circulando no ambiente cavernícola, sendo necessários mais estudos para conhecer o risco de transmissão de leishmanioses nestes locais com alto potencial turístico.Palavras-chave: Cavernas, flebotomíneos, Rondônia, Amazônia.

“…The current study has found 35 species in FD. This number of species is representative of the region, given the fact that 47 species were reported in Goiás, which is approximately 59 times the size of the FD (Almeida et al 2015). Future studies with efforts focused on sampling methods similar to those of the current research and on other vegetation types may be able to reveal a larger species richness in the FD.…”

“…Most cases of leishmaniasis in the Americas originated in Brazil (Alvar et al 2012). Between 2001 and 2012, approximately 3000 confirmed cases of visceral leishmaniasis (VL) and 50,000 of cutaneous leishmaniasis (CL) were reported in the Center-West Region of Brazil (http://www.saude.gov.br), where at least 127 phlebotomine species have been recorded (Almeida et al 2015). This region is largely within the Brazilian Cerrado biome.…”

The Federal District of Brazil (FD) has the lowest Phlebotominae species richness in the country's Midwestern Region. Some of these species have been reported as Leishmania vectors. This study updates the list of sand flies in the FD by sampling 4 gallery forests. Using HP light traps and Shannon traps, 1,209 sand flies were captured and 16 species were identified. The most frequent species was Bichromomyia flaviscutellata (Mangabeira, 1942) (N = 668), followed by Psathyromyia pradobarrientosi (Le Pont, Matias, Martinez & Dujardin, 2004) (N = 285). Brumptomyia guimaraesi , Micropygomyia ferreirana (Martins, Barretto & Pellegrino, 1956), Pa. pradobarrientosi, Br. brumpti (Larrousse, 1920, and Evandromyia bourrouli are reported for the first time in the FD. Sand flies richness in the FD (35 spp.) is relevant when compared to that of the state of Goiás (47 spp.), a state 59 times larger than the FD.
