In the Amazon region the phlebotomine fauna is considered one of the most diverse in the world. The use of Shannon traps may provide information on the anthropophily of the species and improve the traps' performance in terms of diversity and quantity of insects collected when white and black colored traps are used together. This study sought to verify the attractiveness of the traps to the phlebotomine species of the Brazilian Amazon basin using Shannon traps under these conditions. The insects were collected using two Shannon traps installed side by side, one white and the other black, in a primary forest area of the municipality of Xapuri, Acre, Brazil. Samples were collected once a month during the period August 2013 to July 2015. A sample of females was dissected to test for natural infection by flagellates. A total of 6,309 (864 males and 5,445 females) specimens (36 species) were collected. Psychodopygus carrerai carrerai (42%), Nyssomyia shawi (36%), and Psychodopygus davisi (13%), together represented 90% of the insects collected. Nyssomyia shawi and Psychodopygus davisi were more attracted by the white color. Specimens of Nyssomyia shawi, Nyssomyia whitmani, and Psychodopygus hirsutus hirsutus were found naturally infected by flagellates in the mid and hindgut. This is the first study in Acre state using and comparing both black and white Shannon traps, demonstrating the richness, diversity, and anthropophilic behavior of the phlebotomine species and identifying proven and putative vectors of the etiological agents of leishmaniasis.
在亚马逊地区,白蛉类群被认为是世界上最多样化的类群之一。使用香农诱捕器可以提供有关物种嗜人性的信息,并在同时使用白色和黑色诱捕器时,在收集到的昆虫多样性和数量方面提高诱捕器的性能。本研究旨在利用香农诱捕器在这些条件下验证巴西亚马逊河流域白蛉物种对诱捕器的吸引力。在巴西阿克里州沙普里市的一片原始森林地区,并排安装了两个香农诱捕器,一个白色,另一个黑色,用于收集昆虫。在2013年8月至2015年7月期间每月采集一次样本。解剖雌性样本以检测鞭毛虫的自然感染情况。共收集到6309个标本(864只雄性和5445只雌性)(36个物种)。卡氏按蚊(42%)、肖氏白蛉(36%)和戴维斯按蚊(13%),共同占所收集昆虫的90%。肖氏白蛉和戴维斯按蚊对白色更具吸引力。在肖氏白蛉、惠特曼白蛉和多毛按蚊的中肠和后肠中发现了鞭毛虫自然感染的标本。这是阿克里州首次使用和比较黑色和白色香农诱捕器的研究,展示了白蛉物种的丰富性、多样性和嗜人性行为,并确定了利什曼病病原体的已证实和推定传播媒介。
