摘　　要：苹小卷叶蛾是近几年来对果树(包括大棚果树)危害最严重的害虫之一,由于其耐药性强,又具有结网、卷叶习性,尤其是大龄幼虫抗药性严重,因此使用常规农药防治效果不佳。我们测定了3种增效剂对8种农药的增效毒力,并从中筛选出有效药剂进行田间防治试验,为科学治理该害虫的危害提供依据。本试验结果表明,单剂毒死蜱和氟铃脲的防治效果最好,其7 d防效达到60%左右,添加增效剂后的防效达到70%左右。增效醚对供试杀虫剂均有不同程度的增效作用,但增效幅度差别很大,其中对高效氯氰菊酯(P1)、阿维菌素(P5)增效作用最为明显,其7 d防效单剂分别为39.87%和23.97%,添加增效剂后的防效分别为59.31%和43.43%。Adoxophyes orana was one of the pests which damaged fruit trees the most.Conventional pesticides had no satisfying control effect on it because of its strong resistance,especially in older larva,and its habit of netting and rolling leaf.In order to control Adoxophyes orana,the toxicity of 8 insecticides and the synergy effect by 3 synergists were determined in the lab,then field control experiments were conducted on the selected effective insecticides.The results of the experiments showed that the single-agent toxicity of chlorpyrifos and hexafluron had the best control effect,with a 7-day control effect of about 60%,which increased to about 70%after the addition of the synergist.The synergist had a different degree of enhancing effect on the tested insecticides,but the degree of enhancement varied greatly.Among them,the enhancing effect on beta cypermethrin(P1)and abamectin(P5)was the most obvious,with a 7-day control effect of 39.87%and 23.97%,respectively,which increased to 59.31%and 43.43%after the addition of the synergist.
