BackgroundPhlebotomine sand flies (Diptera: Psychodidae) are insects of medical importance due to the role that some species play in the transmission of leishmaniasis. This work aimed to study some ecological aspects among sand flies fauna inhabiting two different environments: the várzea (lowland Amazonian forest) and terra firme (upland Amazonian forest), both located in Tefé Municipality, Amazonas State, Braziland to detect Leishmania infection in those phlebotomine populations.MethodsSand flies were collected using HP light traps. Collection took place over the course of six months: January, February, April, August, September, and October of 2013. To detect natural infection by Leishmania, DNA samples were extracted from female sand flies and submitted to Polymerase Chain Reaction (PCR) targeting the kDNA gene; Leishmania species were identified by PCR-RFLP targeting the hsp70 gene and genetic sequencing.ResultsIn all, 5,716 individuals were collected, and 46 species were identified. Trichophoromyia ubiquitalis (3,330 – 58.26%) and Nyssomyia antunesi (661 – 11.26%) were the most abundant species. Species richness was greater in terra firme environments (42 species) than in the várzea environments (22 species), and forests ecotopes (43 species) were richer than peridomiciles (28 species). DNA of Leishmania was found in Th. ubiquitalis and Psychodopygus davisi, both of which inhabit the terra firme environment and sequencing analysis confirmed the presence of Leishmania (Viannia) lainsoni DNA in Th. ubiquitalis in Tefé Municipality.ConclusionsThe high abundance of Th. ubiquitalis and Ps. davisi and detection of DNA of Leishmania sp. may indicate that both species could be putative vectors for American Cutaneous Leishmaniasis (ACL) in the terra firme environment of Tefé. The sand fly fauna found in várzea is rich and diverse, exhibiting several species, nevertheless the seasonal hydric stress during part of the year that could influence the local diversity, if compared with other studies. This is the first report in Amazonas State of Th. ubiquitalis with presence of L. (V.) lainsoni DNA.

“…To date, approximately 63 200 sandflies species were recorded in the Brazilian Amazon region 64 (Gomes et al, 2013) and, of these, approximately 15 were appoint-65 ed and/or suspected as leishmaniasis vectors (Figueira et al, 2013;66 Alves et al, 2012). Along with this large diversity of sandflies, the 67 Brazilian Amazon region has the largest diversity of Leishmania 68 species of the Neotropical region (Rangel and Lainson, 2003;69 Rotureau, 2006;Figueira et al, 2013). Of the 30 Leishmania species 70 described in the world, at least seven have been found infecting 71 humans in the Brazilian Amazon (Rotureau, 2006).…”

“…Of the 30 Leishmania species 70 described in the world, at least seven have been found infecting 71 humans in the Brazilian Amazon (Rotureau, 2006). North of the 72 Negro and Amazon Rivers, including the states of Amazonas, 73 Amapá, Roraima and Pará, Leishmania (Viannia) guyanensis (Floch,74 1954), is the main etiological agent of American Cutaneous Leish-75 maniasis (ACL), and is associated with most cases (>50%) of human 76 leishmaniasis recorded for the whole Brazilian Amazon (Arias and 77 Freitas, 1978;Romero et al, 2002;Rotureau, 2006;Figueira et al, 78 2013 mining activities, among other factors (Barrett and Senra, 1989;82 Figueira et al, 2013). 83 Lutzomyia (Nyssomyia) umbratilis (Ward and Fraiha, 1977) is the 84 main vector of L. guyanensis in the Brazilian Amazon and Lutzomyia 85 (Nyssomyia) anduzei (Rozeboom, 1942) is recognized as a sec-86 ondary vector of this parasite in the same region (Arias and 87 Freitas, 1978).…”

“…Diversos estudos têm comprovado a adaptabilidade dessa espécie a ambientes modificados (ARAÚJO-PEREIRA et al, 2014;LEONARDO;REBELO, 2004;LAINSON, 2009;REBÊLO et al, 1999;TEODORO et al, 2003) shawi principalmente no Norte do Brasil (LAINSON et al, 1994). Alguns trabalhos relacionam a elevada incidência desse flebotomíneo à variedade de fontes de repasto sanguíneo para as fêmeas, e também a sua fácil adaptação ás condições climáticas variáveis, podendo ser coletada ao longo do ano (REBÊLO et al, 1999;TEODORO et al, 2003) (FIGUEIRA et al, 2013;MISSAWA;MACIEL, 2007;RAMOS et al, 2014;REBÊLO et al, 1999;SILVEIRA et al, 2002) (BUSTAMANTE et al, 2012;GARCIA et al, 2007).
