Survey of sandfly vectors of leishmaniasis in Marambaia Island, municipality of Mangaratiba, State of Rio de Janeiro, Brazil

IntroductionThe influx and efflux of military personnel in the possible endemic areas of leishmaniasis provided the impetus for research on the sandflies on Marambaia Island.MethodsSandflies were collected with light traps installed in the 3 ecotypes of 3 areas chosen for their particular landscape aspects.ResultsIn 2009, were collected 32,006 specimens of sandflies belonging to 13 species. The species that showed highest density were Nyssomyia intermedia and Migoneimyia migonei.ConclusionsN. intermedia and M. migonei are the principal vectors of American tegumentary leishmaniasis (ATL) in Brazil; thus, extension studies related to the eco-epidemiology of these species of Marambaia Island are essential.

引言：利什曼病潜在流行区域内军事人员的往返流动，推动了马拉姆巴亚岛白蛉的相关研究。
研究方法：本研究依据独特景观特征选取3个区域的3种生态型，通过安装灯光诱捕器采集白蛉样本。
研究结果：2009年共采集到13种白蛉，总计32006只标本，其中密度最高的物种为中间尼亚司罗蛉（Nyssomyia intermedia）与米戈内伊氏白蛉（Migoneimyia migonei）。
研究结论：中间尼亚司罗蛉与米戈内伊氏白蛉是巴西美洲皮肤利什曼病（American tegumentary leishmaniasis, ATL）的主要传播媒介；因此，针对马拉姆巴亚岛上述两种白蛉的生态流行病学开展拓展研究至关重要。
