本项研究提示了我省淡色库蚊、家蝇对常用的ＤＤＴ、ＤＤＶＰ、马拉硫磷、二氯苯醚菊酯和溴氰菊酯等五种杀虫剂均已产生了不同程度的抗药性，而且呈上升趋势。尤其ＤＤＶＰ和溴氰菊酯的抗性已很高，淡色库蚊对ＤＤＶＰ的抗性最高达到２１．５倍，家蝇达到１８．４１倍；淡色库蚊对溴氰菊酯的抗性９２年较８６年最高的上升了１７．３倍；对蚊、蝇产生的抗药性，各地都应引起高度的重视，采取措施加以防止抗性的继续升高，合理地使用杀虫剂，以延长杀虫剂的使用寿命。 This study suggests that Culex pipiens pallens and house flies have produced varying degrees of resistance to five commonly used insecticides such as DDT, DDVP, malathion, permethrin and deltamethrin Medicinal, but also an upward trend. DDVP and deltamethrin in particular, the resistance is very high, Culex pipiens pallens DDVP resistance up to 21.5 times, housefly 18.41 times; Culex pipiens pallensatum deltamethrin resistance 92 years Up 17.3 times from the highest level in 1986; the resistance to mosquitoes and flies should be given high priority all over the country, and measures should be taken to prevent the resistance from continuing to rise and pesticides should be rationally used to prolong and kill Pesticide life.
