摘要: 目的:探讨家蝇抗药性状况及防制对策。方法:自动微量点滴法。结果:1996年广东省家蝇对DDVP、巴沙、氯菊酯、溴氰菊酯的LD50分别为0.2507~0.5382、12.5803~94.5318、0.0519~0.4160和0.0111~0.0346μg/虫,比1991年耐药性增大2.17~26.99倍。对多重抗性家蝇的防制策略:以环境治理为主的综合防制、交替轮换或镶嵌用药、现场应用效果监测等。结论:5年间家蝇对3类杀虫剂产生不同程度的抗药性。

Abstract: Seven field-collected strains of the housefly, Musca domestica, were tested for resistance to 4 different insecticides, DDVP, Bassa, Permethrin and Deltamethrin by the topical applications method in comparison with a known susceptible strain. The LD50 of DDVP, Bassa, Permethrin and Deltamethrin for the houseflies were 0.2507~0.5382, 12.5803~94.5318, 0.0519~0.4160 and 0.0111 ~0.0346μg/♀ respectively. Resistance ratios ranged from 0.15 to 3.58 in 1991, and increased 3.70 ~25.28 times in 1996. It was discussed that the management strategies of resistant houseflies in Guangdong Province.
