摘　　要：7种药剂对青檀绵叶蚜室内毒力测定结果显示,1.8%阿维菌素EC、0.5%苦参碱AS、4.5%高效氯氰菊酯EC、0.3%印楝素EC、10%吡虫啉WP毒力较大,5种药剂的LC50分别为1.556、2.897、3.894、4.080和7.982 mg/L。选用毒力较大的这5种药剂进行林间药效试验。结果表明:1.8%阿维菌素EC、4.5%高效氯氰菊酯EC、10%吡虫啉WP3种非植物源杀虫剂速效性较好,施药1 d后即表现出对青檀绵叶蚜很好的防效,3种药剂的林间校正死亡率均达到90%以上,7 d后均达到了95%以上;而2种植物源杀虫剂则速效性相对较差,但7 d后也均达到了90%以上的防效。The toxicity determination of the 7 pesticides against Shivaphis pteroceltis showed that 1.8% abamectin EC, 0.5%matrine AS, 4.5% beta-cypermethrin EC, 0.3% azadirachtin EC, and 10% imidacloprid WP had a higher toxicities againstShivaphis pteroceltis. And their LC50 were 1.556、2.897、3.894、4.080 and 7.982 mg/L. So we chose 5 higher toxicitypesticides to conduct the field efficacy trials. The result showed that three kinds of the botanical pesticides 1.8% abamectinEC, 4.5% beta-cypermethrin EC, and 10% imidacloprid WP had better field control efficacy on the Shivaphis pteroceltis afterone day, and their corrected mortality were more than 90%, after 7 days reached more than 95%. But two kinds of botanicalpesticide field control efficacy were slower, and their corrected mortality were more than 90% after 7 days.
