Abstract: Objective To explore the efficacy of a mixture of common chemical insecticides and biological insecticides against Culex pipiens pallens, and to provide a scientific basis for establishing reasonable and effective mosquito control measures. Methods The larval impregnation method and drug complex formulation method were applied to measure the resistance and synergistic coefficients of Cx. pipiens pallens against two biological insecticides and four chemical insecticides. Results The resistance coefficients of Cx. pipiens pallens against Bacillus thuringiensis subsp. israelensis and B. sphaericus were 1.02 and 1.08 times, respectively, and the resistance coefficients against cypermethrin, deltamethrin, DDVP, and propoxur were 97.00, 59.08, 6.44, and 2.36 times, respectively. The synergistic coefficient of deltamethrin+DDVP, deltamethrin+propoxur, cypermethrin+DDVP, and cypermethrin+propoxur were 156.24-182.37, 163.28- 201.36, 166.23-190.56, and 160.23-199.58, respectively. The synergistic effect of DDVP+ propoxur was not good. Conclusion Culex pipiens pallens in Jining city has developed varying degrees of resistance to common chemical insecticides, but is still sensitive to biological insecticides. It is suggested that biological insecticides or chemical insecticide mixtures be applied to control mosquito breeding and mitigate the development of insecticide resistance.

摘要: 目的 探讨常用化学杀虫剂复配以及生物杀虫剂对现场淡色库蚊的杀灭效果,为制定合理有效的蚊虫防治措施提供科学依据。方法 采用幼虫浸渍法及药物复配方法,测试现场淡色库蚊对2种生物杀虫剂与4种化学杀虫剂的抗性及增效系数。结果 现场淡色库蚊对苏云金芽孢杆菌以色列亚种和球形芽孢杆菌的抗性倍数分别为1.02和1.08倍,对氯氰菊酯、溴氰菊酯、敌敌畏和残杀威的抗性倍数分别为97.00、59.08、6.44和2.36倍,溴氰菊酯+敌敌畏、溴氰菊酯+残杀威、氯氰菊酯+敌敌畏、氯氰菊酯+残杀威复配共毒系数分别为156.24~182.37、163.28~201.36、166.23~190.56和160.23~199.58,敌敌畏+残杀威复配效果不佳。结论济宁市城区淡色库蚊对常用化学杀虫剂产生不同程度抗性,对生物杀虫剂表现敏感,建议采取生物杀虫剂或化学杀虫剂复配方式控制蚊虫孳生,减缓抗药性发展。
