摘　　要：以叶片残留法,在室内测定了农田常用除草剂和杀虫剂对莲草直胸跳甲成虫的影响。试验结果表明:在常用浓度下,2,4-滴丁酯、草甘膦、丁草胺、氟草烟、灭草松、吡氟乙草灵、二甲戊乐灵、烯禾啶、杀螟丹、杀虫双处理后,对莲草直胸跳甲成虫的校正死亡率均小于50%,说明上述农药在常用浓度下对莲草直胸跳甲成虫影响不大;而百草枯、草酮、乐果、敌敌畏、氯氟氰菊酯、鱼藤酮·氰戊菊酯处理后,对莲草直胸跳甲的校正死亡率均大于50%,说明上述农药在常用浓度下对此影响较大。The bioactivities of 16 species of chemical were tested against the adult of Agaslcles laygropnlia by me leai residue method. The results showed that with the average consideration the adjusted mortality of 2,4-D butylate, glyphosate, butachlor, fluroxypyr, bentazone, haloxyfop, pendimethalin, sethoxydim, paraquat and oxadiazon were under 50%. 10 species of herbicide had no infection to the adult ofAgasicles hygrophila. But the mortality of 6 species of pesticide were above 50% and had great infection to Agasicles hygrophila.
