摘　　要：应用埃普利诺菌素浇泼剂驱除牦牛皮蝇幼虫,并设埃普利诺菌素注射剂药物对照组和阳性对照组。结果:剖检埃普利诺菌素浇泼剂300μg/kg,400μg/kg,500μg/kg剂量组牦牛与药物对照埃普利诺菌素注射剂组及伊维菌素浇泼剂组牦牛,均未检出皮蝇1期幼虫,而阳性对照组牦牛皮蝇1期幼虫感染率35.0%,平均感染强度29.4(9～53)条。翌年3、5月份两次触摸检查牛背部皮下瘤疤和皮肤虫孔,4个药物试验组牦牛均未检出,而阳性对照组牦牛两次检查平均感染率45.16%,平均感染强度6.45个。试验证明埃普利诺菌素浇泼剂低、中、高3个剂量对寄生于牦牛的皮蝇幼虫驱净率、驱虫率均达100.0%,高效安全。Repelling effect was studied by using pour-sprinkling preparation of eprinomectin in yaks infected with Hypoderma larvae,eprinomectin injection and not giving drug as control group.The results of autopsy showed that there wasn＇t L1 larvae of Hypoderma in experiment group with eprinomectin pour-sprinkling preparation in dose of 300,400,500μg/kg and control group with eprinomectin injection and ivermectin pour-sprinkling preparation.The infectious rate of L1 larvae of Hypoderma of positive control group was 35.0%,the average infectious intensity was 29.4（9-53）; four groups with drug hadn＇t find hypoderma through touched the back on March and May next year.The average infectious rate of positive control group was 45.16%, the average infectious intensity was 6.45.This experiment proved that the repelling clean rate and repelling rate of eprinomectin pour-sprinkling preparation with lower, medium and high dose were all 100%,It have good effective and safe.
