摘要
目的 :探讨大庆城市家蝇对常用杀虫剂的抗药性状况 ,研究制定防制对策 ;方法 :采用WHO规定的微量点滴法 ;结果 :大庆市 1999— 2 0 0 1年氯菊酯LD50 分别为 0 0 0 63 6μg/只、0 99964 μg/只、0 0 5 784μg/只 ,溴氰菊酯LD50 分别为 0 0 0 2 79μg/只、0 0 0 617μg/只、0 0 0 63 8μg/只 ,敌敌畏LD50 分别是 0 0 0 95 4μg/只、0 2 7468μg/只、0 180 0 5 μg/只 ;结论 :家蝇对氯菊酯和溴氰菊酯的抗药性呈逐年增长的趋势 ,均处于低抗的水平 ,可以继续使用 ,但必须科学合理 ,敌敌畏的抗药性也有变化 ,今后在家蝇防制中要以抗药性监测结果为指导 ,注意轮换用药、镶嵌用药。
Objective:To Monitor the insecticide resistance condition of fly in Daqing.Methods:Using the method of topical application as WHO stipulated.Results:In 1999,2000 and 2001,the LD 50s of permethrin were 0.006 36 μg/insect,0.009 64 μg/insect,0.057 84 μg/insect against house fly respectively in Daqing city.The LD 50s of deltamethrin were 0.002 79 μg/insect,0.006 17 μg/insect and 0.006 38 μg/insect.The LD 50s of dichlorvos were 0.009 54 μg/insect ,0.274 68 μg/insect and 0.180 05 μg/insect.Conclusion:The house flys resistance to permethrin and deltamethrin increased gradually,but it was still at low level.These insecticides could be continuously used in a scientific way.The resistance to dichlorvos changed.Insecticides to control the fly should be applied in consideration of resistance monitoring results.A comprehensive controlling method had good effect.
