摘　　要：通过应用阿维·三唑磷对杨干象幼虫期进行防治试验,结果表明,阿维·三唑磷点涂杨干象取食刻痕毒杀效果显著,以5倍液浓度防治效果最佳。通过其他触杀能力强、有代表性的菊酯类和磷制剂农药进行效果试验,结果表明,阿维.三唑磷杀虫效果最佳,防治期以5月10—20日进行为宜。Experiment of controlling larvae of Cryptorhynchus lapathi by using abamectin·triazophos was conducted.Result shows that：abamectin·triazophos dispensing notch feeding C.lapathi have significant cytotoxicity effect;5 times the concentration have the optimal control effect.Through effect test on pesticides with other stronger contact ability,representative pyrethrins phosphorus pesticide formulations,result shows that the avermectin·triazophos have the optimal insecticidal effect,and control period is on May 10-20 at the appropriate.
