| 摘 要： | 目的了解武汉市江夏区家蝇对5种常见杀虫剂的抗性水平,为科学合理使用杀虫剂提供依据。方法采用微量点滴法,检测江夏区家蝇野外种群对DDVP、甲基吡恶磷、高效氯氰菊酯、胺菊酯、氯氰菊酯5种杀虫剂的抗性水平。结果 2010年江夏区家蝇对DDVP和胺菊酯的抗性较低,LD50分别为0.19927和0.65550μg/♀,抗性倍数均在10倍以内,属低抗性(或耐药性);对氯氰菊酯和高效氯氰菊酯均已产生高抗性,LD50分别为0.81560和0.64850μg/♀,抗性倍数分别为177.3和231.6倍。结论应根据抗药性调查结果科学合理使用杀虫剂,提倡综合防治。

| Abstract: | Objective To provide a scientific basis for fly control by investigating resistance of Musca domestica to five common insecticides in Jiangxia district, Wuhan city. Methods The resistance of M. domesticato DDVP,azamethiphos,beta cypermethrin,tetramethrin and cypermethrin were measured by topical application methods.Results M. domesticahad low resisiteance to DDVP (LD50=0.199 27 μg/♀) and beta cypermethrin (LD50=0.655 50 μg/♀), with the resistance ratio below 10-fold.M. domesticahad devoloped high resistance to cypermethrin (LD50=0.815 60 μg/♀) and propoxur (LD50=0.648 50 μg/♀), and the resistances ratio to the two insecticides was 177.3 and 231.6 respectively.Conclusion It is essential to use insecticides reasonably based on researches of M. domestica’s resistance. It is also important to develop comprehensive prevention and control strategies. |
