摘要
目的掌握南阳市家蝇抗性现状,为抗性的发生发展提供科学依据。方法采用微量点滴法。结果家蝇对敌敌畏、溴氰菊酯、高效氯氰菊酯、残杀威的LD50依次为0.567 0、0.105 2、0.288 0,>132.44μg/蝇。结论南阳市家蝇对4种杀虫剂产生了较高的抗性,对敌敌畏的抗性发展相对缓慢,应实施综合治理、合理用药,抑制和延缓抗药性的发展。
Objective To investigate the present resistance situation of Musca domestica to four kinds of insecticides in Nanyang and provide scientific evidence for its development. Methods Topical method was used . Results In Nanyang city,LD50 of DDVP, dehamethrin , beta - cypermethrin ,propoxur were 0. 567 0,0. 105 2,0. 288 0, 〉 132.44 μg per fly. Conclusion Musca domestica has high resistance to the four kinds of insecticides,but the resistance to DDVP has increased rather slowly. It is indicated that the integrated management and rational employment of insecticides can restrain and delay the resisitance development of Musca domestica.
