在病媒生物综合防治中应用化学杀虫剂控制家蝇密度成为主要的防治手段之一。由于长期大量使用化学杀虫剂,家蝇抗药性不断增加。20世纪80年代,银川市测定了家蝇对5种杀虫剂的抗性[1],近20多年未再开展抗药性监测。为掌握银川市家蝇对常用杀虫剂的抗性水平,了解其抗性动态进行了调查。 The application of chemical insecticides to control housefly densities in integrated vector control has become one of the major control measures. Musca domestica has become increasingly resistant due to its long-term use of chemical insecticides. In the 1980s, Yinchuan City tested the resistance of five kinds of insecticides to house flies [1], and no drug resistance monitoring was conducted in the past 20 years. To understand the resistance of house flies to commonly used insecticides in Yinchuan City, we investigated the dynamics of their resistance.
