有机磷、有机氯杀虫剂在卫生害虫防治方面曾发挥了重要作用,由于长期大量使用,害虫对杀虫剂抗性逐年增高,给除害工作带来一定困难。我市在八十年代初开始使用少量的拟除虫菊酯类杀虫剂,为了做好抗性的监测工作,我们于1985～1987年开展了家蝇对五种杀虫剂的抗性监测,现将结果报 Organophosphorus and organochlorine pesticides have played an important role in the prevention and control of pests of pests. Due to the long-term extensive use, pest insecticide resistance increases year by year, which brings certain difficulties to the pest elimination work. In the early 1980s, the city began to use a small amount of pyrethroid insecticides. To monitor the resistance, we conducted housefly resistance monitoring of five insecticides from 1985 to 1987, The results reported
