摘要[目的]筛选防治刺槐突瓣细蛾的有效药剂。[方法]采用小区试验研究不同杀虫剂对刺槐突瓣细蛾成虫、幼虫的田间药效。[结果]对于成虫，施药后72 h，高效氯氰菊酯防治效果达93.3%～98.1%；灭幼脲悬浮剂的防治效果达85.7%～94.3%；阿维菌素乳油防治效果为81.0%～84.0%。对于幼虫，施药后72 h，灭幼脲悬浮剂的防治效果达93.7%～95.1%；乐斯本乳油防治效果达83.8%～86.3%；10%吡虫啉可湿性粉剂防治效果为77.2%～79.2%。[结论]灭幼脲对刺槐突瓣细蛾成虫和幼虫均有较好的防治效果。

Abstract[Objective] Insecticides were screened out for controlling Chrysaster ostensackenella.[Method] The field efficacy of different insecticides on the larvae and adult of C.ostensackenella was studied by plot test.[Result] For adults，the control effects of beta cypermethrin against C.ostensackenella were between 93.3% and 98.1%；the control effects of chlorbenzuron against C.ostensackenella were between 85.7% and 943%；the control effects of abamectin against C.ostensackenella were between 81.0% and 84.0%.For larvae，the control effects of chlorbenzuron against C.ostensackenella were between 93.7% and 95.1%；the control effects of lorsban against C.ostensackenella were between 83.8% and 86.3%；the control effects of imidacloprid against C.ostensackenella were between 77.2% and 79.2%.[Conclusion] Chlorbenzuron can be applied for controlling the larvae and adult of C.ostensackenella.

刺槐（Robinia pseudoacacia L.）原产于北美洲，17世纪引入我国并大量栽培。刺槐用途很多，可作为畜牧业的辅助饲料、优质的木材树种、造林和绿化行道树以及矿区植被的重建树种等，但刺槐害虫种类较多，包括蛀茎、蛀干、蛀根害虫，造瘿害虫，食叶害虫等[1]。

刺槐突瓣细蛾（Chrysaster ostensackenella）属于鳞翅目食叶害虫中的潜叶类害虫[2]。刺槐突瓣细蛾仅在北美洲有危害报道，之前在原产地以外地区未有分布。但在2015年，刘腾腾等[3]首次发现刺槐突瓣细蛾入侵我国境内山东烟台和辽宁沈阳，为害刺槐。刺槐突瓣细蛾是继刺槐叶瘿蚊后，又一个入侵至我国的原产自北美洲的刺槐害虫，应引起相关造林绿化和植物检疫部门的重视。近年来，该虫在徂徕山发生非常严重，危害率近100%。……
