采用8d无选择摄毒法检测山西省隰县长尾仓鼠对第2代抗凝血类灭鼠剂溴敌隆的抗药性。结果表明,溴敌隆对长尾仓鼠毒杀率为89.5%,死亡鼠平均食毒剂量为2.99 mg/kg,平均致死时间为9.24d,存活鼠平均食毒剂量为3.50mg/kg,抗性发生率为10.5%。研究认为,长尾仓鼠对溴敌隆已经形成了抗药性个体,但并未产生抗药性种群。
The drug resistance of broiler 2nd generation anti-clotting rodenticides to bromadiolone was tested by 8d selective exposure method. The results showed that the toxicity of bromadiolone to long-haired hamster was 89.5%, the average dose of dead rats was 2.99 mg / kg, the average lethal time was 9.24 days and the average dose of surviving mice was 3.50 mg / kg, and the resistance The incidence was 10.5%. Studies suggest that long-haired hamsters have formed resistant individuals to bromadiolone, but did not develop resistant populations.
