The sheep body louse Damalinia ovis is a potentially serious problem affecting the value of the fleece and possibly causing reduced weight gains. Control has been based on the dipping or showering of sheep using insecticidal oil in water emulsions. The results using a pour-on formulation of the synthetic pyrethroid cypermethrin to control louse infestation are reported. Application rates of 5 mg/kg or more gave 99 to 100 per cent control.
绵羊体虱（Damalinia ovis）是一个潜在的严重问题，它会影响羊毛的价值，并可能导致体重增加减缓。控制方法一直是使用水包油型杀虫药对绵羊进行药浴或喷淋。本文报道了使用合成拟除虫菊酯氯氰菊酯的浇泼剂来控制虱子感染的结果。5毫克/千克或更高的施用量可实现99%至100%的防治效果。
