Blood meals from 579 Lutzomyia longipalpis (Diptera:Psychodidae), collected in an endemic focus of American visceral leishmaniasis in Colombia, were identified by precipitin test. Sand fly collections were made during a 16-month period from the inside walls of two houses, a pigpen, and rock crevices in a small community (El Callejon) within the endemic area. Feeding patterns of the sand flies varied with locality and date of collection. Overall, bovine feedings predominated, but feedings were also recorded on pigs, equines, humans, dogs, opossums, birds, and reptiles. Calculation of the forage ratios for each host species indicated that cows and pigs were the preferred hosts of Lu. longipalpis in El Callejon. Results of this study suggest that Lu. longipalpis is an opportunistic feeder and is not highly anthropophilic nor strongly attracted to dogs.
通过沉淀试验对从哥伦比亚美洲内脏利什曼病流行区采集的579只长须罗蛉（双翅目：毛蠓科）的血餐进行了鉴定。在16个月的时间里，从流行区内一个小社区（埃尔卡列洪）的两所房屋的内墙、一个猪圈和岩石裂缝中采集了白蛉。白蛉的摄食模式因采集地点和日期而异。总体而言，以牛为食占主导，但也记录到以猪、马、人、狗、负鼠、鸟类和爬行动物为食。对每种宿主物种的觅食比率计算表明，牛和猪是埃尔卡列洪长须罗蛉的首选宿主。本研究结果表明，长须罗蛉是一种机会性摄食者，对人类的嗜性不高，对狗的吸引力也不强。
