“…This highlights the possibility that these species may participate in the transmission of ACL in both of the environments studied in Tefé. Some studies of fauna in the várzea environment have identified insects of medical importance, such as mosquitoes and biting midges [ 45 - 47 ]; however, there is little information about sand flies [ 48 ]. This is because the várzea environment is difficult to access during rainy seasons, and because flooding makes field work more arduous; yet flooding may have a direct impact on the habitats of insect fauna.…”

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.

“…Apesar dos vários estudos realizados quanto à culicidofauna em território brasileiro (urBinatti et al, 2001;BarBosa et al, 2003;MarCondes et al, 2003;taipe-lagos & natal, 2003;HutCHings et al, 2010;Morais et al, 2012), esta é a primeira lista de espécies para uma área urbana localizada no Cerrado baiano. Desta forma, os resultados aqui obtidos revestem-se de importância epidemiológica, já que alguns dos táxons identificados podem atuar na veiculação de patógenos e/ ou causar grande desconforto e reações alérgicas através da picada, promovendo a diminuição da qualidade de vida da população humana conforme já apontado por lopes et al (1995) e teodoro et al (1995) para áreas urbanas do sul do país.…”

A região oeste da Bahia passa por acelerado processo de desenvolvimento agrícola, o que tem gerado problemas de infraestrutura nos municípios. A falta de saneamento básico e de coleta dos resíduos são alguns desses problemas, os quais têm papel importante no aumento de criadouros disponíveis aos culicídeos. Assim, considerando as possibilidades de contato entre vetor e população humana, o objetivo deste trabalho foi estudar a fauna de culicíeos adultos em uma área urbana no oeste da Bahia e verificar a presença de espécies de interesse em saúde pública. As amostragens de mosquitos adultos foram realizadas no município de Barreiras, de fevereiro de 2009 a janeiro de 2010, das 17h30min às 21h00min. Ao total foram capturados 1.744 mosquitos e oito gêneros foram identificados: Aedes, Coquilletidia, Culex, Limatus, Mansonia, Ochlerotatus, Psorophora e Uranotaenia. Culex quinquefasciatus foi a espécie mais frequente e abundante. Outras espécies encontradas, e que apresentam importância epidemiológica, foram Aedes aegypti e Ochlerotatus scapularis. Considerando que muitas espécies coletadas em Barreiras possuem importância epidemiológica e ocorrem mesmo durante a estação seca devido à ausência de saneamento básico, é importante que os municípios da região oeste da Bahia sejam alvo constante das atividades de vigilância epidemiológica.
