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 经对雷州半岛内湛江市区的赤坎区和霞山区、徐闻县城区、廉江市安铺镇区捕捉的257只褐家鼠、165只黄胸鼠,进行抗药性监测,褐家鼠暂未发现抗药性个体;黄胸鼠的抗性率为7 .88%,其存活摄药剂量在145. 90mg/kg以上,按家栖鼠抗药性检验标准,黄胸鼠产生抗药性个体。结论 雷州半岛的鼠类控制工作仍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。
Objective To study the resistant change of Rattus to anticoagulant rodenticide . Methods Taking tests without selectivity on rodents.Results The rodents caught in four districts of Leizhou island were tested. The results showed that resistance had not been found on Rattus norvegicus. Rattus flavipectus had individual resistance ,the resistance rate was 7.88%.The dosage from the survivors was up to 145.90 mg/kg.Conclusion The anticoagulant rodenticide could be still used in Leizhou island but should be used scientifically and properly with careful tests of sensitivity.
