OBJECTIVE
To assess the efficacy of zeta-cypermethrin pour-on to control cattle lice.
DESIGN
Five field trials in south-eastern Australia.
PROCEDURE
Zeta-cypermethrin pour-on, deltamethrin pour-on and pour-on vehicle were applied to groups of 10 cattle. Lice were counted before treatment and 14, 28, 42 and 56 days after treatment.
RESULTS
Zeta-cypermethrin pour-on given at 2.5 mg/kg was equivalent to, or marginally more effective than a deltamethrin pour-on at 0.75 mg/kg. It eliminated B bovis and H eurysternus and gave good control of L vituli and S capillatus. Zeta-cypermethrin at 1 mg/kg gave good control of B bovis and H eurysternus but was not satisfactory against L vituli and S capillatus.
CONCLUSION
Zeta-cypermethrin pour-on, given at 2.5 mg/kg, is an effective treatment for cattle lice control. Zeta-cypermethrin, and other synthetic pyrethroid pour-ons, are the treatment of choice to control B bovis.
目的
评估高效氯氰菊酯浇泼剂防治牛虱的效果。
设计
在澳大利亚东南部进行五项田间试验。
步骤
将高效氯氰菊酯浇泼剂、溴氰菊酯浇泼剂和浇泼剂载体分别施用于每组10头牛。在治疗前以及治疗后14、28、42和56天对牛虱进行计数。
结果
以2.5毫克/千克剂量使用的高效氯氰菊酯浇泼剂与0.75毫克/千克剂量的溴氰菊酯浇泼剂效果相当，或略优于后者。它能消灭牛血虱和宽额血虱，并能很好地控制牛痒螨和牛毛细虱。1毫克/千克的高效氯氰菊酯能很好地控制牛血虱和宽额血虱，但对牛痒螨和牛毛细虱的防治效果不理想。
结论
以2.5毫克/千克剂量使用的高效氯氰菊酯浇泼剂是防治牛虱的有效方法。高效氯氰菊酯以及其他拟除虫菊酯浇泼剂是防治牛血虱的首选治疗方法。
