摘要
目的探讨斯氏屋顶鼠对抗凝血灭鼠剂的抗药性变化。方法参照全国鼠类抗药性监测协作组统一方法,进行无选择性摄毒试验。结果经对广州市所辖9个区内所捕获的53只斯氏屋顶鼠进行抗药性监测,存活率为3.8%,其总平均摄药剂量为30.31mg/kg,存活平均摄药剂量为58.29mg/kg。经与同期同地家栖鼠抗药性比较,该鼠种对第一代抗凝血灭鼠剂敏感性介于黄胸鼠与褐家鼠之间。结论控制斯氏屋顶鼠可使用第一代抗凝血灭鼠剂,但应加强对灭鼠药物的敏感性监测,科学、合理用药。
Objective To study the resistance of Rattus rattus sladeni to anticoagulant rodenticide. Methods No-choice food test was used in this study according to the method of national rodent resistance surveillance group. Results The rodents caught in nine districts of Guangzhou were tested. The survival rate was 3.8%. The total average dosage was 30.31 mg/kg, and survival average dosage was 58.29 mg/kg. The result showed that its sensitivity to anticoagulant rodenticide was between R.tanezumi and R.norvegicus. Conclusion The anticoagulant rodenticide can be still used to the control ofR.rattus sladeni. But it should strengthen the resistance surveillance, and the chemicals should be used scientifically and rationally.
