Over a complete two-year period, phlebotomine specimens were caught in an area of cutaneous leishmaniasis occurrence in the municipality of Angra dos Reis. A manual suction tube was used to catch phlebotomines on house walls, and also light traps in domestic and peridomestic settings and in the forest. This yielded 14,170 specimens of 13 species: two in the genus Brumptomyia and eleven in the genus Lutzomyia. L. intermedia predominantly in domestic and peridomestic settings, with little presence in the forest, with the same trend being found in relation to L. migonei, thus proving that these species have adapted to the human environment. L. fischeri appeared to be eclectic regarding location, but was seen to be proportionally more endophilic. L. intermedia and L. migonei were more numerous in peridomestic settings, throughout the year, while L. fischeri was more numerous in domestic settings except in March, April, May and September. From the prevalence of L. intermedia, its proven anthropophily and findings of this species naturally infected with Leishmania (Viannia) braziliensis, it can be incriminated as the main vector for this agent of cutaneous leishmaniasis in the study area, especially in the peridomestic environment. L. fischeri may be a coadjuvant in carrying the parasite.
在整整两年的时间里，在安格拉杜斯雷斯市的一个皮肤利什曼病发病地区采集了白蛉标本。使用手动吸管在房屋墙壁上捕捉白蛉，同时也在家庭及周边环境和森林中设置诱虫灯捕捉。这共采集到14170个标本，分属于13个物种：2个属于Brumptomyia属，11个属于Lutzomyia属。中间罗蛉主要分布在家庭及周边环境，在森林中很少见，米氏罗蛉也呈现相同趋势，这证明这些物种已适应人类环境。费氏罗蛉在分布地点上似乎较为多样，但按比例来看更倾向于嗜人血。中间罗蛉和米氏罗蛉在全年的周边环境中数量更多，而费氏罗蛉除了3月、4月、5月和9月外，在家庭环境中数量更多。鉴于中间罗蛉的高感染率、已证实的嗜人性以及发现该物种自然感染巴西利什曼原虫（维阿尼亚种），可认定它是研究区域内这种皮肤利什曼病病原体的主要传播媒介，尤其是在周边环境中。费氏罗蛉可能是携带寄生虫的辅助媒介。
