摘　　要：核桃举肢蛾是核桃上的重要害虫,严重影响核桃的产量和质量,为了有效控制其危害,研究了性诱剂诱杀及地面处理防治核桃举肢蛾的效果。结果表明,采用性诱剂诱杀、冬季树冠下土壤深翻10~20 cm、成虫羽化出土前地面喷施40%的辛硫磷乳油200倍液或48%的毒死蜱乳油200倍液防治核桃举肢蛾,防治效果分别为12.5%~22.9%、43.8%~62.5%、36.1%~38.9%,3种单一防治措施均不能有效控制核桃举肢蛾的发生危害；采用冬季树冠下土壤深翻20 cm＋成虫出土前地面喷施40%的辛硫磷乳油200倍液或48%的毒死蜱乳油200倍液综合措施防治,防治效果明显,防效分别为76.1%~79.2%、75.2%~77.2%,可以较好地控制核桃举肢蛾的发生危害。Atrijuglans hetaohei is a major pest in walnut orchard and affects the fruit yield and quality seriously. In order to validly control the pest,this experiment studied the prevention and control effect of sex attractant and ground treatment on Atrijuglans hetaohei. The results showed that the control rate of sex attractant trapping,deep ploughing 10—20 cm under canopy in winter,spraying 40% phoxim EC diluted 200 times or 48% chlorpyrifos EC diluted 200 times and shallow hoeing before adult eclosion from soil were 12. 5%—22. 9%, 43. 8%—62. 5% and 36. 1%—38. 9%, respectively. Three kinds of single control measures could not effectively control the occurrence and damage of Atrijuglans hetaohei. The control effect of deep ploughing 20 cm under canopy in winter and spraying 40% phoxim EC diluted 200 times or 48% chlorpyrifos EC diluted 200 times followed by shallow hoeing before adult eclosion from soil was 76 . 1%—79 . 2% or 75 . 2%—77 . 2%. The comprehensive measure could effectively reduce the damage of Atrijuglans hitauhei.
