Plastic tags containing 8.5 per cent w/w cypermethrin or 10 per cent w/w permethrin reduced the severity of damage caused to sheep by the headfly Hydrotaea irritans. A similar pattern of protection extended from the tagged ewes to their untagged lambs. Tags containing 8.5 per cent w/w fenvalerate failed to reduce the level of headfly damage in gimmers.
含有8.5%（重量/重量）氯氰菊酯或10%（重量/重量）氯菊酯的塑料标签减轻了厩螫蝇对绵羊造成的损伤严重程度。类似的保护模式从带标签的母羊延伸到未带标签的羔羊。含有8.5%（重量/重量）氰戊菊酯的标签未能降低青年母羊的厩螫蝇损伤水平。
