摘　　要：目的了解沧州市家蝇对常用杀虫剂的抗性水平,为病媒生物防治及杀虫剂的合理使用提供科学依据。方法采用点滴法测定家蝇对杀虫剂的半数致死量(LD50)。结果家蝇对胺菊酯、顺式氯氰菊酯、高效氟氯氰菊酯和溴氰菊酯的抗性倍数分别为29.51、41.38、29.06、271.33,均属高抗水平;甲基吡噁磷抗性倍数为9.12,属低抗水平。结论沧州市家蝇对拟除虫菊酯类药物产生了较高的抗药性,应科学合理使用化学杀虫剂,减缓抗药性的产生。Objective To understand the insecticides resistance level of Musca domestica in Cangzhou,and provide scientific basis for medical vector control and rational use of insecticides. Methods Determining the median lethal dose of Musca domestica with topical appliction method. Results Musca domestica in Cangzhou developed 29. 51,41. 38,29. 06 and 271. 33 folds resistance respectively to tetramethrin,alpha-cypermethrin,beta-cyfluthrin and deltamethrin,and 9. 12 folds to azamethiphos. Conclusion Musca domestica were highly resistant to pyrethroid insecticides in Cangzhou. Insecticides should be used reasonably to delay the produce of resistance.
