目的测定了山东省滕州市、泰安市、济宁市淡色库蚊对残杀威杀虫剂的敏感性和残杀威与三种增效剂复配对淡色库蚊的杀灭效果。方法采用WHO生物测试法。结果残杀威+S1增效系数分别在2.23～8.02之间;残杀威+S2在2.19～9.49之间;残杀威+增效胺的增效系数分别为1.06～4.30之间。显示出较好的增效作用。结论当淡色库蚊对残杀威产生抗药性后,合理应用氨基甲酸酯类杀虫剂与增效剂混用的方法 ,能取得较好的防治效果。 Objective To determine the susceptibility of Culex pipiens pallens in Tengzhou, Taian and Jining, Shandong Province, China, and the killing effect of propoxur and the three synergists on Culex. Methods The WHO biological test method. Results The propofol + S1 symbiosis coefficient was between 2.23 and 8.02 respectively; the propoxur + S2 was between 2.19 and 9.49; the synergistic coefficients of propoxur and synergistic amines were between 1.06 and 4.30. Show better synergy. Conclusion When Culex pipiens pallens resistant to carbofuran, the rational use of carbamate insecticide and synergist mixed method can achieve better control effect.
