Flebotom??neos da Amaz??nia Central e quatro novos registros para o estado do Amazonas, Brasil

Abstract

Flebotom??neos da Amaz??nia Central e quatro novos registros para o estado do Amazonas, Brasil. Um levantamento foi conduzido em maio e junho de 2008 para estudar a fauna de insetos da Amaz??nia Central, Brasil. Como parte desta pesquisa, foram registradas 60 esp??cies de um total de 13.712 esp??cimes pertencentes a 13 g??neros. Os locais de coleta localizaram-se na fronteira dos estados do Par?? e do Amazonas, incluindo tr??s munic??pios do estado do Amazonas (Borba, Mau??s e Nhamund??). Armadilhas do tipo Malaise, CDC e Shannon foram utilizadas para coletar os insetos. A maioria dos flebotom??neos foi coletada em armadilhas CDC (89,5%), enquanto que as armadilhas Malaise e de Shannon coletaram 7% e 3,5%, respectivamente. Os g??neros mais abundantes, representando 97,1% do total de flebotom??neos identificados foram: Trichopygomyia Barretto, 1962 (47,6%), Psathyromyia Barretto, 1962 (17,9%), Psychodopygus Mangabeira, 1941 (17,5%) e Trichophoromyia Barretto, 1962 (14,3%). Os g??neros com o maior n??mero de esp??cies identificadas foram Psychodopygus (14), Psathyromyia (10), Evandromyia Mangabeira, 1941 (7), Trichophoromyia (5) e Trichopygomyia (5). A esp??cie mais abundante foi Trichopygomyia trichopyga (Floch & Abonnenc, 1945) a qual representou 29% do total de flebotom??neos identificados. Tamb??m s??o registradas quatro novas esp??cies para o estado do Amazonas: Ps. complexus (Mangabeira, 1941), Ps. llanosmartinsi Fraiha & Ward, 1980, Ty. pinna (Feliciangeli, Ramirez-P??rez & Ramirez, 1989), e Th. readyi (Ryan, 1986). Os resultados deste estudo fornecem informa????es novas e adicionais sobre a distribui????o de flebotom??neos da Amaz??nia e aumenta o n??mero de esp??cies no estado do Amazonas de 127 para 131.Sand flies from Central Amazonia and four new records for the Amazonas state, Brazil. A survey was conducted in May and June 2008 to study the fauna of insects in Central Amazonia, Brazil. As part of the survey, we report here that sixty species of phlebotomine were identified, totaling 13,712 specimens from 13 genera. The collection sites were located at the border between the states of Par?? and Amazonas, comprising three municipalities from the Amazonas state (Borba, Mau??s, and Nhamund??). Malaise, CDC and Shannon traps were used to collect the insects. Most of the sand flies were collected by CDC traps (89.5%), while Malaise and Shannon traps collected 7% and 3.5%, respectively. The most abundant genera, representing 97.1% of the total sand flies identified were: Trichopygomyia Barretto, 1962 (47.6%), Psathyromyia Barretto, 1962 (17.9%), Psychodopygus Mangabeira, 1941 (17.5%) and Trichophoromyia Barretto, 1962 (14.3%). The genera with the largest number of species identified were: Psychodopygus (14), Psathyromyia (10), Evandromyia Mangabeira, 1941 (7), Trichophoromyia (5) and Trichopygomyia (5). The most abundant species was Trichopygomyia trichopyga (Floch & Abonnenc, 1945), which represented 29% of the total sand flies identified. Here we also report new records for four species in the Amazonas state: Ps. complexus (Mangabeira, 1941), Ps. llanosmartinsi Fraiha & Ward, 1980, Ty. pinna (Feliciangeli, Ramirez-P??rez & Ramirez, 1989), and Th. readyi (Ryan, 1986). The results of this study provide new, additional information on the distribution of sand flies in the Amazon and increase the number of species in the Amazonas state from 127 to 131
