摘要: 目的 探讨家栖鼠对抗凝血灭鼠剂的抗药性变化。方法 按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 经对江门市城区(蓬江、江海、新会区)内所捕获的129只褐家鼠、37只黄胸鼠、15只小家鼠进行抗药性监测,其抗性率分别为0、10.81%和46.67%,总平均摄药剂量分别为12.00、143.12和582.41 mg/kg,按家栖鼠抗药性检验标准,小家鼠对第一代抗凝血剂杀鼠灵已形成抗药性种群,黄胸鼠有抗药性个体产生。结论 以小家鼠为优势种的场所,要考虑使用第二代抗凝血灭鼠剂;而以褐家鼠、黄胸鼠为主的场所,则可继续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。

Abstract: Objective To study the resistant development of anticoagulant rodenticide in commensal rodents.Methods Unselective feeding method was used,which was established by "Rodenticide-resistance Monitoring Cooperation Group in China" in 1985.Results The rodents(129Rattus norvegicus,37 R.flavipectus and 15 Mus musculus) caught in Jiangmen' three city zone(Pengjiang,Jianghai,Xinhui) of Jiangmen city were tested.The resistance rate differs from 0,10.81% and 46.67% for R.norvegicus,R.flavipectus andM.musculus with average taken dosages 12.00,143.12 and 582.41 mg/kg respectively.The result shows that M.musculus have developed resistance to anticoagulant rodenticide Ⅰ and R.flavipectus has individual resistance.Conclusion The rodenticide Ⅱ should be used in the areas of M.musculus.The anticoagulant rodenticide Ⅰ can be still used but should be used scientifically and properly with careful tests of sensitivity.
