摘要:

目的 了解丽水市致倦库蚊、家蝇自然种群对常用卫生杀虫剂的抗性现状,为合理使用杀虫剂和指导灭蚊、蝇工作提供依据。方法 采用药液浸渍法,测定4龄期蚊幼虫半数致死浓度;点滴法,测定家蝇半数致死量。结果 致倦库蚊自然种群对仲丁威、三氯杀虫酯抗性倍数较低,接近于敏感品系;而对溴氰菊酯、氯菊酯、高效氯氰菊酯、敌敌畏的抗性分别为9.0、5.5、5.4和4.8倍;家蝇自然种群对三氯杀虫酯、胺菊酯、氯菊酯抗性较低,属低抗水平,对敌敌畏(10.9倍)属中抗水平,而对高效氯氰菊酯(20.8倍)和溴氰菊酯(38.6倍)属高抗水平。结论 丽水市自然种群对7种杀虫剂存在不同程度的抗药性。

Abstract:

Objective To determine the resistance of the natural populations of Culex pipiens quinquefasciatus and Musca domestica to commonly used pesticides in Lishui, providing the basis for proper insecticidal administration and development of mosquito and fly control. Methods The drug immersion method was employed to measure the median lethal concentration for fourth-instar larval mosquitoes, and topical application was conducted to determine the half lethal dose for the adult flies. Results The resistance ratios of the natural populations of Cx. pipiens quinquefasciatus to BPMC and acetophenate were at a low level close to those of susceptible lines; and the ratios to deltamethrin, permethrin, beta cypermethrin and dichlorvos were 9.0, 5.5, 5.4 and 4.8 times, respectively. The resistance of the natural populations of M. domestica was at a low level to acetophenate, tetramethrin and permethrin, an intermediate level to dichlorvos (10.9 times) and a high level to beta cypermethrin (20.8 times) and deltamethrin (38.6 times). Conclusion The natural populations of flies and mosquitoes had varied resistance to the 7 insecticides in Lishui.
