In two leishmaniasis endemic foci of the Pacific coast of Ecuador, where the primary forest is severely attacked by human settlements, intradomiciliary sandfly catches, with light trap and human bait, have been carried out from August 1991 to October 1992. The presumed vector Lutzomyia trapidoi was by far the dominant species inside dwellings at Paraiso Escondido in the preandean hills (86% of the anthropophilic sandfly population, and 8.5 females/night catch by light trap). Not a single Lu. gomezi was caught in this village. At La Tablada, Lu. gomezi was the dominant anthropophilic species in the coastal cordillera (83% of anthropophilic sandfly population and 3.7 females/night catch by light trap); Lu. trapidoi accounted only for 4.6% of the total catches in this village. On human bait, catches were variable depending on the day and on the season, but dominant species were always the same. The percentage of Lu. trapidoi was higher on human bait than in light trap. Blood meal identifications of engorged Lu. gomezi and Lu. trapidoi confirmed the anthropophily of these two species in the houses.
在厄瓜多尔太平洋沿岸的两个利什曼病流行疫源地，原始森林受到人类定居点的严重侵袭，于1991年8月至1992年10月使用灯光诱捕器和人饵进行了室内白蛉捕捉。在安第斯山前丘陵地带的埃斯孔迪多帕拉伊索，假定的传播媒介特拉皮多伊卢蛉是室内的主要物种（占嗜人白蛉种群的86%，灯光诱捕器每晚捕获8.5只雌蛉）。在这个村庄没有捕获到一只戈麦斯卢蛉。在拉塔布拉达，戈麦斯卢蛉是沿海山脉的主要嗜人物种（占嗜人白蛉种群的83%，灯光诱捕器每晚捕获3.7只雌蛉）；特拉皮多伊卢蛉仅占这个村庄总捕获量的4.6%。使用人饵时，捕获量因日期和季节而异，但优势物种始终相同。特拉皮多伊卢蛉在人饵上的捕获比例高于灯光诱捕器。对饱血的戈麦斯卢蛉和特拉皮多伊卢蛉进行的血餐鉴定证实了这两个物种在房屋内的嗜人性。
