Bloodmeal sources of Lutzomyia spp. were determined, using the bloodmeal analysis precipitin test, in Chaute, Lima, Peru, an area endemic for cutaneous leishmaniasis (uta). From April 1990 to May 1991, sandflies were sampled in and around the village houses, with CDC light traps and a Shannon trap with protected human bait, respectively. Overall, 1424 sandflies were collected engorged. In indoor collections, human blood (N = 275) was the most frequent bloodmeal found, followed by cow (171) and cat (152). The most frequent bloodmeals of the flies caught in the Shannon trap collections were from cow (31), man (23) and cat (23). Of the two predominant sandfly species in the area, Lutzomyia peruensis was more anthropophilic than Lu. verrucarum (chi 2 = 14.13, P < 0.001). The sandflies from Chaute appear to be opportunistic feeders; 16 different hosts were identified. There was evidence of bloodmeals from more than one host in each of 151 sandflies, including bloodmeals containing blood from an animal only present within the houses mixed with blood from animals only present in the corrals near the house. Some sandflies must therefore have flown from the corrals to the houses (or vice versa) to take the last bloodmeals before their capture.
在秘鲁利马的乔特地区，一种皮肤利什曼病（uta）的流行区，使用血餐分析沉淀素试验确定了秘鲁罗蛉属白蛉的血餐来源。1990年4月至1991年5月，分别使用疾控中心诱虫灯和带有受保护人体诱饵的香农诱捕器在村庄房屋内外对白蛉进行采样。总共收集到1424只饱血的白蛉。在室内采集的样本中，人血（N = 275）是最常见的血餐，其次是牛血（171）和猫血（152）。在香农诱捕器采集的白蛉中，最常见的血餐来自牛（31）、人（23）和猫（23）。在该地区两种主要的白蛉物种中，秘鲁罗蛉比疣罗蛉更嗜人血（卡方 = 14.13，P < 0.001）。乔特地区的白蛉似乎是机会性摄食者；已确定16种不同的宿主。在151只白蛉中，每只都有取食不止一种宿主血液的证据，包括含有仅在房屋内出现的动物血液与仅在房屋附近畜栏中出现的动物血液混合的血餐。因此，一些白蛉必定是从畜栏飞到房屋（或反之），在被捕获前吸食了最后一顿血餐。
