本文总结了１９８６～１９９４年辽宁省部分代表性地区家蝇对溴氰菊酯的抗性监测结果，显示１９８８年之前抗性发展较为平缓；到１９９０年，占调查总数８０％地区的家蝇达到高抗水平；１９９３年，所有调查地区的家蝇均达到高抗水平，其中５０％地区的家蝇达到最高抗水平；１９９４年，占调查总数８０％地区的家蝇达到最高抗水平，其中锦州地区家蝇相对抗性达６６７倍。同时比较了调查地区家蝇对顺式氯氰菊酯的抗性状况，表明１９９０～１９９４年间的抗性增长了７倍多，并有向更高水平发展的趋势。据此，提出了延缓家蝇抗性发展的相应对策。
This article summarizes the monitoring results of housefly resistance to deltamethrin in some representative areas of Liaoning Province from 1986 to 1994 and shows that the development of resistance was milder before 1988. By 1990, housefly accounted for 80% of the surveyed population In 1993, houseflies in all survey areas reached high resistance levels, of which 50% of domestic flies reached the highest level of resistance; in 1994, houseflies accounted for the highest level of resistance in 80% of the surveyed areas, of which Jinzhou The relative resistance of house flies is 667 times. At the same time, the resistant status of housefly to cypermethrin in the survey area was compared, indicating that the resistance increased more than 7 times from 1990 to 1994 and the trend toward higher level development. Accordingly, put forward the appropriate measures to delay the development of housefly resistance.
