目的了解青岛市淡色库蚊幼虫对4种常用杀虫剂的抗药性现状,为合理选用杀虫剂,指导蚊虫防治提供科学依据。方法采用WHO生物测定方法,测定淡色库蚊幼虫对常用杀虫剂的抗性水平。结果与敏感品系比较,淡色库蚊幼虫对残杀威和敌敌畏抗性为低抗水平,对溴氰菊酯的抗药性为中等水平,对氯氰菊酯呈高抗性。结论青岛市淡色库蚊对4种常用杀虫剂均产生不同程度的抗药性,应采取适当措施克服或延缓蚊虫抗药性的产生和发展。

Objective To investigate the resistance of Culex pipiens pallens larvae to 4 kinds of common used insecticide in Qingdao,and guide the control of Culex pipiens pallens larvae by choosing appropriate chemical insecticide.Methods Insecticidal resistance of Culex pipiens pallens larvae was measured using a standard WHO bioassay.Results Compared with the laboratory susceptible strain,the resistance of Culex pipiens pallens larvae to DDVP and propoxur was in lower level. Its resistance to trichlorine was in medium level. Culex pipiens pallens larvae to cypermethrin had the highest resistance. Conclusion Culex pipiens pallens in Qingdao has generated different degrees of resistance to the 4 kinds of common used chemical insecticides. Therefore appropriate measures should be taken to prevent or delay the emergence and development of insecticidal resistance in mosquitoes.
