江苏省家蝇对敌敌畏、溴氰菊酯、二氯苯醚菊酯等杀虫剂的抗性,曾在1982、1984、1985年进行了调查。嗣后,由于许多地区长期、大量使用杀虫剂灭成蝇、处理蝇幼孳生地和成蝇栖息场所,导致家蝇抗性不断增加,影响了杀灭效果。为此,我们于1991、1992两年采用全国统一的点滴法,在全省范围内(11个省辖市)开展了抗性调查,并分析其发展趋势,为制订综合防治措施提供了科学依据。调查结果:江苏省家蝇对敌敌畏的LD_(50)为0.1807μg/雌,是1982年(LD_(50)0.0470μg/雌)的3.84倍。以徐州、镇江、常州等市的抗性水平较
The resistance of houseflies to insecticides such as dichlorvos, deltamethrin, and permethrin in Jiangsu Province was investigated in 1982, 1984, and 1985. Subsequently, as long-term and extensive use of pesticide-killing flies in many regions, the treatment of flies and flies habitat, leading to the increase of housefly resistance, affecting the killing effect. Therefore, in 1991 and 1992, we adopted a unified national drip method to conduct resistance surveys in the province (11 provincial cities) and analyzed their development trend, which provided a scientific basis for formulating comprehensive prevention and control measures . The results showed that the LD_ (50) of housefly in Jiangsu Province to dichlorvos was 0.1807μg / female, which was 3.84 times of that in 1982 (LD_ (50) 0.0470μg / female). To Xuzhou, Zhenjiang, Changzhou and other cities than the level of resistance
