在雌性采采蝇（舌蝇和舌蝇）上局部施用一种叫做吡丙醚的幼年激素模拟物，通过阻止其后代在蛹期的发育而有效地使其绝育。1989年7月至11月期间，在津巴布韦赞比西河流域Rekomitjie研究站附近12.3平方公里的毛丝革鼠和白斑革鼠林地栖息地内，用吡丙酯处理了41个气味诱捕器。进入诱捕器的采采蝇与剂量为2mg /cm2的吡丙醚擦过，然后让其逃逸。3个月后，小区内两种蝇蛹的羽化率分别降至对照水平的30%和2.7%。各物种解剖的750多只蛹中，发育不完全的蛹占78%，发育不完全的蛹占94%。在试验期间，该区域取样的雌性苍白棘球蚴的平均卵巢年龄类别增加了一倍。这是由于老苍蝇的迁徙和出生率的下降，如果在一大片地区持续一年，估计足以导致种群减少到原来水平的10（-6）。
The juvenile hormone mimic, pyriproxyfen, applied topically to female tsetse flies, Glossina morsitans morsitans Westwood and G. pallidipes Austen, effectively sterilizes them by arresting development of their offspring in the pupal stage. Between July and November 1989, 41 odour baited traps treated with pyriproxyfen were deployed near Rekomitjie Research Station, Zambezi Valley, Zimbabwe, in a 12.3 km2 block of woodland habitat of G. m. mositans and G. pallidipes. Tsetse entering the traps brushed against material dosed with 2 mg/cm2 pyriproxyfen and were then allowed to escape. Emergence rates from pupae of the two species collected in the block fell to 30% and 2.7%, respectively, of control levels after three months. Of more than 750 pupae of each species dissected 78% and 94%, respectively, showed incomplete development. The average ovarian age category of female G. pallidipes sampled in the block doubled during the trial. This was due to immigration of older flies and the declining birth rate which, if sustained over a large area for a year, was estimated as sufficient to cause a population reduction to 10(-6) of its original level.
