From 1996 to 1999 multi-trapping methods (Center of Diseases Control, CDC) light traps, light-baited Shannon traps, and aspiration on tree bases) were used to study the phlebotomine fauna of the "Serra do Navio" region of the Brazilian State of Amapá, which is part of the Guiana Shield. Fifty-three species were identified among 8,685 captured individuals. The following species, associated with the transmission of American cutaneous leishmaniasis in Amazonian Brazil, were captured: Nyssomyia umbratilis (3,388), Psychodopygus squamiventris maripaensis (995), Ny. anduzei (550), Trichophoromyia ubiquitalis (400), Ny. whitmani (291), Ps. paraensis (116), and Bichromomyia flaviscutellata (50). Flagellate infections were detected in 45 flies. Of the 19 parasites isolated in vitro, 15 were Leishmania (Viannia) guyanensis (13 in Ny. umbratilis, 1 in Ny. whitmani, 1 in Ny. anduzei) and three were L. (V.) naiffi (2 in Ps. s. maripaensis, 1 in Ny. anduzei). The results indicate the participation of three phlebotomine species in the transmission of L. (V.) guyanensis and two species in that of L. (V.) naiffi, and show that the same phlebotomine species is involved in the transmission of different Leishmania (Viannia) species in the Guianan/Amazon region. A review of the literature together with the results of the present study, and other published and unpublished results, indicate that eight phlebotomine species potentially participate in the transmission of Leishmania (Viannia) naiffi in Amazonia.
1996年至1999年期间，采用多种诱捕方法（疾病控制中心，CDC；灯光诱捕器、灯光诱饵香农诱捕器以及在树干基部进行抽吸）对巴西阿马帕州“塞尔拉多纳维奥”地区的白蛉种群进行了研究，该地区是圭亚那地盾的一部分。在捕获的8685只个体中鉴定出53个物种。捕获了以下与巴西亚马逊地区美洲皮肤利什曼病传播相关的物种：荫蚋（Nyssomyia umbratilis，3388只）、鳞腹南美罗蛉（Psychodopygus squamiventris maripaensis，995只）、安杜齐蚋（Ny. anduzei，550只）、泛在毛蠓（Trichophoromyia ubiquitalis，400只）、惠特曼蚋（Ny. whitmani，291只）、帕拉南美罗蛉（Ps. paraensis，116只）以及黄盾二色蚋（Bichromomyia flaviscutellata，50只）。在45只白蛉中检测到鞭毛虫感染。在体外分离出的19种寄生虫中，15种为圭亚那利什曼原虫（Viannia亚种）（13种在荫蚋中，1种在惠特曼蚋中，1种在安杜齐蚋中），3种为奈菲利什曼原虫（L. (V.) naiffi）（2种在鳞腹南美罗蛉中，1种在安杜齐蚋中）。结果表明，三种白蛉物种参与了圭亚那利什曼原虫（Viannia亚种）的传播，两种白蛉物种参与了奈菲利什曼原虫的传播，并且表明在圭亚那/亚马逊地区，同一白蛉物种参与了不同利什曼原虫（Viannia亚种）的传播。结合本研究结果以及其他已发表和未发表的结果对文献进行综述表明，有八种白蛉物种可能参与了亚马逊地区奈菲利什曼原虫的传播。
