摘　　要：本研究探究了4种杀虫剂对薄壳山核桃上暗影饰纹夜蛾和桃蛀螟的防效。试验结果表明,从杀虫效果看,供试药剂中20%氯虫苯甲酰胺SC 3000、2000倍液,5.7%甲维盐水分散粒剂3000倍液防效最佳,防效达100.0%;10%虫螨腈SC 3000倍液防效较低,防效达78.6%;其他药剂处理防效均在84.6%~91.5%。从保果效果看,20%氯虫苯甲酰胺SC 3000、2000倍液效果最佳,2次调查的保果效果为88.0%~100.0%;10%虫螨腈SC 2000~3000倍液,2次调查保果效果较差;其他药剂处理第1次的保果效果在74.9%~100.0%,第2次的保果效果均低于60.0%。暗影饰纹夜蛾和桃蛀螟钻蛀危害对单粒重影响不大,但产生较多的虫粪污染内果皮,导致果实品相较差。20%氯虫苯甲酰胺SC 2000、3000倍液对上述2种虫害有较好防效,鉴于经济成本,推荐3000倍液。In the study,the control effects of four insecticides on the fruit borers of Carya illinoensis against Characoma ruficirra and Dichocrocis punctiferalis were determined.Results showed that the insecticidal effects of insecticides with 3000 times,2000 times of 20%chlorantraniliprole SC and 3000 times of 5.7%emamectin benzoate WG were 100%;3000 times of 10%chlorfenapyr SC was 78.6%.The insecticidal effect of other insecticides were between 84.6%and 91.5%.The effects of fruit preservation with 3000 times and 2000 times of 20%chlorantraniliprole SC was the best,which were between 88.0%-100.0%.According to two surveys,2000 times and 3000 times of 10%chlorfenapyr SC were worst.The first survey of other insecticides showed that the fruit preservation effects were between 74.9%-100.0%.The second survey of other insecticides showed that the effects of fruit preservation were all less than 60.0%.The two borer pests had no effect on seed weight,but they produced a great deal of frass which polluted endocarp,leading to worse appearance of fruit.The control effects of 2000 times and 3000 times of 20%chlorantraniliprole SC on Curya illinonesis against the fruit brorer were best.Considering economic factors,it is suggested to use 3000 times of 20%chlorantraniliprole.
