Merino ewe lambs (n = 500) were used in a trial to assess the efficacy of cypermethrin in preventing blowfly strike on sheep. Three hundred of these lambs were treated with 300 mg cypermethrin each and run as a separate flock. One hundred lambs were used as untreated controls and a further 100 lambs were treated topically with a larval growth regulator as treated control animals. It was found that the synthetic pyrethroid afforded total protection for 3 weeks against strike by Lucilia cuprina. The blowfly challenge was heavy, and 26% of the untreated control animals were struck in the 4 week trial period.
美利奴母羊羔（n = 500）被用于一项试验，以评估氯氰菊酯预防绵羊蝇蛆病的效果。其中300只羊羔每只接受300毫克氯氰菊酯治疗，并作为一个单独的羊群饲养。100只羊羔用作未处理的对照，另外100只羊羔局部使用幼虫生长调节剂作为处理过的对照动物。结果发现，合成拟除虫菊酯在3周内对铜绿蝇的侵袭提供了全面保护。蝇蛆挑战很严重，在4周的试验期内，26%的未处理对照动物受到侵袭。
