“…It demonstrates that this environment is still very poorly described with regard to the invertebrate fauna, for which the only descriptions that exist are in relation to tick species (ALVES et al, 2011;LABRUNA et al, 2008;NAVA et al, 2010). There are more than fifteen known caves in Rondônia, and this number may be much higher.…”

“…Over recent years, sandflies have been found in other environments with human intervention such as fragmented forests and peridomestic areas, thus showing high adaptive capacity (PESSOA et al, 2007;PEREIRA et al, 2015). Caves are environments in which sandflies have been frequently found (ALVES et al, 2011;BARATA & APOLINÁRIO, 2012;CARVALHO et al, 2013). Inside caves, some factors are favorable to the sandflies' life cycle, like humidity, temperature, organic matter and little or no presence of light (ALENCAR et al, 2011;WILLIAMS, 1976).…”

“…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).…”

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.
