摘　　要：目的了解山东省淡色库蚊对常用化学杀虫剂的抗性状况,为合理有效地进行蚊虫化学防治提供依据。方法采用WHO生物测定方法,测定淡色库蚊敏感品系和现场种群对5种杀虫剂的抗性。结果 6个现场淡色库蚊种群对DDT、DDVP、马拉硫磷、残杀威、溴氰菊酯的抗性指数分别为1.59～28.48、2.22～15.72、2.36～5.50、3.40～6.33、8.50～36.00倍。结论山东省淡色库蚊对5种常用化学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 evaluate the resistance of Culex pipiens pallens to commonly used chemical insecticides in Shandong province, providing the basis for proper and efficient administration of insecticidal chemicals. Methods The WHO bioassay was used to test the resistance of susceptible strains and field populations of Cx. pipiens pallens to 5 kinds of insecticide. Results Of 6 field populations of Cx. pipiens pallens, the resistance indices for DDT, DDVP, malathion, propoxur and deltamethrin were 1.59-28.48, 2.22-15.72, 2.36-5.50, 3.40-6.33 and 8.50-36.00. Conclusion Cx. pipiens pallens in Shandong province has generated different degrees of resistance to the 5 commonly used chemical pesticides. Therefore, appropriate measures should be taken to prevent or delay the emergence and development of insecticidal resistance in mosquitoes.
