【摘要】 目的：探讨山东省不同地区家蝇对化学杀虫剂的抗药性现状。方法：采用常规点滴法。结果：不同地区家蝇对拟除虫菊酯类的抗性水平普遍较高；对有机磷类，则用量大、使用频率高的地区抗性水平较高；个别地区对氨基甲酸酯类的抗性发展很快；对停用多年的有机氯类，已恢复到非常敏感的水平。结论：家蝇抗药性水平高低，与化学杀虫剂用量大小和使用频率高低密切相关。更多还原

【Abstract】 The current insecticide resistance of house fly in different regions Of Shandong province were presented. The results demonstrate that there were a high resistance level to pyrethroid in all regions; there were a high resistance level in region where organophosphate were used frequently and in high quantities; the resistance to carbamate developed quickly in some regions; and the resistance to organochlorine, which has been banned for many years, have recovered to a very sensitive level. The cause for resistance’s development and the Strategy to delay it’s development in house fly were discussed.更多还原
