| 摘 要： | 目的为了延缓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,测定了常用杀虫剂复配对微山湖区韩庄镇淡色库蚊幼虫的杀灭作用。方法采用WHO生物测试法,计算LC50回归方程、增效系数。结果 DDVP＋三氯杀虫酯、残杀威＋三氯杀虫酯复配共毒系数,分别为164.39~171.08和188.28~221.84,显示出较好的增效作用。DDVP＋残杀威复配效果较差。结论当淡色库蚊产生抗药性后,采用有机磷或氨基甲酸酯类杀虫剂与有机氯类杀虫剂混用的方法,能取得较好效果。

| Abstract: | Aim The efficacy of compound insecticides in killing Culex pipiens pallens larvae in Weishan Lake area were bioassayed.Methods WHO standard bioassay was employed to calculate LC50,regression equation and synertic coefficients of compound insecticides in killing Culex pipiens pallens larvae.Results The synergistic coefficients of DDVP ＋ Acetofenate,propoxur ＋ Acetofenate against mosquitoes were 164.39~171.08 and 188.28~221.84,respectively,showing significant synergism,but the synergism of DDVP ＋ propoxur was low.Conclusion The mixtures of orgnaophosphorus or carbamate insecticides with organochlorine ones may have better control efficacy after the resistance of mosquitoes occurred to insecticides. |
