Lutzomyia wellcomei (Fraiha, Shaw & Lainson) (Diptera: Psychodidae) can act as an important vector of Leishmania (Viannia) braziliensis This study presents the results of collections carried out in a fragment of Atlantic Forest in a Conservation Unit of Rio Grande do Norte state. Collections occurred over 12 consecutive months using Shannon and CDC traps. A total of 777 sand flies from eight species were collected: Lutzomyia walkeri (Newstead), Lutzomyia evandroi (Costa Lima & Antunes), Lutzomyia wellcomei (Fraiha, Shaw & Lainson), Lutzomyia sordellii (Shannon & Del Ponte), Lutzomyia brasiliensis (Costa Lima), Lutzomyia lenti (Mangabeira), Lutzomyia longipalpis (Lutz & Neiva), and Lutzomyia abonnenci (Floch & Chassignet). Lutzomyia wellcomei was the most abundant species using the Shannon trap (97%) and L. walkeri in the CDC trap (81%). It is important to note the abundance of L. wellcomei in Shannon trap collections, which favors the capture of anthropophilic species. Lutzomyia wellcomei was only present in months where rainfall was above 100 mm, confirming it as a species adapted to wetter months.
威氏白蛉（Lutzomyia wellcomei）（弗雷哈、肖和兰森）（双翅目：毛蠓科）可作为巴西利什曼原虫（Leishmania (Viannia) braziliensis）的重要传播媒介。本研究展示了在北里奥格兰德州一个保护单位的大西洋森林片段中进行采集的结果。使用香农诱捕器和疾控中心诱捕器连续12个月进行采集。共采集到来自8个物种的777只白蛉：沃氏白蛉（Lutzomyia walkeri）（纽斯特德）、埃氏白蛉（Lutzomyia evandroi）（科斯塔·利马和安图内斯）、威氏白蛉（Lutzomyia wellcomei）（弗雷哈、肖和兰森）、索氏白蛉（Lutzomyia sordellii）（香农和德尔蓬特）、巴西白蛉（Lutzomyia brasiliensis）（科斯塔·利马）、伦氏白蛉（Lutzomyia lenti）（曼加贝拉）、长须白蛉（Lutzomyia longipalpis）（卢茨和内瓦）以及阿氏白蛉（Lutzomyia abonnenci）（弗洛赫和沙西涅）。在香农诱捕器中，威氏白蛉是数量最多的物种（97%），而在疾控中心诱捕器中，沃氏白蛉数量最多（81%）。值得注意的是香农诱捕器采集到的威氏白蛉数量众多，这有利于捕获嗜人血物种。威氏白蛉仅出现在降雨量超过100毫米的月份，这证实它是一种适应较湿润月份的物种。
