“…This species has already been found in Roraima, Amazonas and Pará, which are all states in the Brazilian Amazon region (FREITAS & BARRETT, 2002;GAMA et al, 2010;RYAN, 1986). The finding of these two species increases the number of sandflies registered in Rondônia: recently, Galardo et al (2015) elevated the number of species in Rondônia to 118 and, with our findings, this number is updated to 120 species.…”

“…In general, most of the species collected in the present study are commonly found in open areas (GALARDO et al, 2015;GIL et al, 2003GIL et al, , 2009PEREIRA et al, 2015). However, the presence of these species inside caves may not be accidental, and is probably due to the presence of food resources and shelter, even if temporarily, as suggested in some other studies (ALVES et al, 2011;WILLIAMS, 1976).…”

“…Pintomyia gruta was found by Galardo et al (2015) in Rondônia but the authors do not mention this species as a new record for Rondônia. This species had been exclusively found in caves in Serra do Carajás, Pará (RYAN, 1986), which until now was the only environment associated with this species.…”

“…The only study on the sandfly fauna of caves in the Brazilian Amazonian region was conducted in the municipality of Presidente Figueiredo, state of Amazonas (ALVES et al, 2011). In the state of Rondônia, there are very few studies about these insects and none relating to cave environments (BIANCARDI et al, 1982;GIL et al, 2003GIL et al, , 2009GALARDO et al, 2015;TELES et al, 2013). Therefore, the present study was the first project conducted in Rondônia with the aims of studying sandfly fauna in caves and ascertaining whether any proven or potential vectors of leishmaniasis were present in caves.…”

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.

“…In Brazil, it is currently considered the main vector of AVL in all regions; however, its presence was not yet detected in the states of Acre, Amazonas, Rondônia, and Santa Catarina. The ability of L. (L.) longipalpis to often feed on domestic and synanthropic animals, as well as its remarkable anthropophily favored its adaptation to changing environments, favoring the maintenance of the transmission cycle in the rural environment and, at the same time, the spread of the disease into urban areas [9][10][11][12].…”

Leishmaniases are considered serious public health problems, and their geographical expansion has enabled their establishment in urban areas of medium and large cities in Brazil. Continuous processes of deforestation, construction of dams, and hydroelectric plants, among others, cause environmental impact and may favor the increase in the number of human cases of leishmaniases, as well as the establishment of epidemic outbreaks. This scenario reflects the reality of some regions of Brazil, such as Tocantins State, which in recent years has recorded high levels of American visceral leishmaniasis (AVL). This study is aimed to analyze environmental and epidemiological factors related with the spatial and temporal distribution of AVL and with the occurrence of Lutzomyia (Lutzomyia) longipalpis, the main vector of AVL, in the state of Tocantins. The results indicate that the vector is adapted to all environments, especially the ones under human influence, and that anthropogenic environmental impacts can support the development and adaptation of AVL in Brazil. Such information could be applied in control strategies aimed at decreasing AVL incidence.
