摘　　要：目的测定常用杀虫剂对山东省滨湖地区现场淡色库蚊幼虫的敏感性及其与S1、MGK264复配后的增效作用,以了解和克服蚊虫抗性的发生和发展,更好地选用卫生杀虫剂控制蚊虫。方法采用WHO生物测试法,计算LC50、回归方程、增效系数。结果滨湖地区淡色库蚊对5种杀虫剂均产生了不同程度的抗性。S1和MGK2642种增效剂分别与DDVP、残杀威、氯氰菊酯复配杀灭东平湖区淡色库蚊,增效系数分别在3.10～6.17、3.98～7.74、6.48～9.91和1.08～1.90、1.63～2.37、3.93～4.33之间,对杀虫剂均显示出较好的增效作用。结论当淡色库蚊产生抗药性后,采用杀虫剂与增效剂混用的方法,可收到较好的灭蚊效果。Objective To measure Culex pipierts pallens la,＇val sensitivity to common insecticides and the effects after combined with S~ and MGK264 in order to provide evidence of the development of resistance. Methods WHO-recommended bioassays were employed to calculate the LCs0, regression equation and synergistic coefficients. Results Lakefront Cx. pipiens pallens had varying degrees of resistant to five insecticides. The synergistic coefficients of DDVP, propoxur and cypermethrin were 3.10-6.17, 3.98-7.74, 6.48-9.91, respectively, and after combination with S~ and MGK264 1.08-1.90, 1.63-2.37, 3.93-4.33, respectively. Reported synergistic coefficients show satisfying synergetic effects. Conclusion The combination of synergistic insecticides may result in a good killing effect for resistant Cx. pipiens pallens.
