1993年3月开始进行调查，以查明耶鲁农牧区牛死亡率高的原因。非洲动物锥虫病被认为是主要的限制因素，发病率超过30%，因此有理由于1994年3月/4月开始执行舌蝇控制方案。在每年6个月的旱季期间，每两个月用1%溴氰菊酯浇泼处理所有牛，并展示1500个杀虫剂浸渍目标，有助于减少采采蝇种群（Glossina tachinoides和G. morsitans submorsitans）超过90%。在不到7个月的时间内，AAT的发生率下降到5%以下，并在整个干预期间保持在该水平，直到1996年6月，尽管治疗间隔增加到3个月。平均PCV值从干预前的26.5- 30.9%显著增加至干预期间的30.7-36.3%。总体健康状况的改善导致生育能力和牛奶产量的恢复，使利奥的乳制品得以销售，从而为富拉尼族妇女创造了约3美元/天的毛收入。
Investigations to identify the causes of high mortalities in cattle in the agropastoral zone (ZAP) of Yale started in March 1993. African animal trypanosomosis (AAT) was found to be the major constraint, with incidence rates exceeding 30%, justifying a tsetse control programme, which started in March/ April 1994. The treatment of all cattle at bimonthly intervals with deltamethrin 1% pour on and the display of 1500 insecticide impregnated targets during the 6 months of the dry season each year helped to reduce the tsetse populations (Glossina tachinoides and G. morsitans submorsitans) by more than 90%. In less than 7 months, the incidence of AAT dropped below 5% and remained there throughout the intervention until June 1996, in spite of an increase to 3 months in the interval between the treatments. Mean PCV values increased significantly from 26.5-30.9%, before, to 30.7-36.3% during the intervention. The improvement in the overall health resulted in a resumption in fertility and milk production, allowing the sale of dairy products in Leo, thus creating a gross income of about $US3/day for the Fulani women.
