本文报道了宁波市家蝇对7种化学杀虫剂的抗性调查,结果表明,含氰基类杀虫剂的抗性有明显增加,尤其是溴氰菊酯和氯氰菊酯,其抗性比1981年—1983年分别增加65.71倍和54.24倍;不含氰基类杀虫剂的抗性增幅相对较慢。认为更换农药或停用1～2年后,可降低抗性水平;同时应大力提倡综合性灭蝇措施。
In this paper, a survey on the resistance of house flies to seven chemical insecticides in Ningbo was carried out. The results showed that the resistance of the pesticides containing cyanogens increased significantly, especially deltamethrin and cypermethrin, Year-1983 increased by 65.71 times and 54.24 times; non-cyanide insecticide-resistant growth is relatively slow. Considering that pesticides should be replaced or disabled for 1-2 years, the level of resistance should be reduced. At the same time, comprehensive measures for killing fly should be advocated.
