[Objective] Insecticides were screened out for controlling Acantholyda posticalis.[Method] The field efficacy of different insecticides on the larvae ofA.posticalis was studied by plot test.[Result] After 72 hours,the best control effects of thiacloprid against A.posticalis of the 1st instar larvae were between 94.7％ and 96.9％.For the 2nd instar larvae,the best control effects of thiacloprid against A.posticalis were between 89.7％ and 93.0％.For the 3rd instar larvae,the best control effects of thiacloprid against A.posticalis were between 88.9％ and 91.0％.[Conclusion] Thiacloprid can be applied for controlling the larvae of A.posticalis.And the best control period of A.posticalis is the 1 st instar larvae.%[目的]筛选防治松阿扁叶蜂的有效药剂.[方法]采用小区试验研究不同杀虫剂对松阿扁叶蜂不同龄期幼虫的田间药效.[结果]施药后72 h,对于1龄幼虫,噻虫啉微囊悬浮剂的防治效果达94.7％～96.9％;高效氯氰菊酯的防治效果达92.6％ ～94.9％;多杀霉素的防治效果为86.8％ ～ 88.9％.对于2龄幼虫,噻虫啉微囊悬浮剂的防治效果达89.7％ ～ 93.0％;高效氯氰菊酯的防治效果达88.2％ ～ 90.4％;多杀霉素的防治效果为81.4％ ～ 83.3％.对于3龄幼虫,噻虫啉微囊悬浮剂的防治效果达88.9％ ～ 91.0％;高效氯氰菊酯的防治效果达87.1％ ～89.2％;多杀霉素的防治效果为81.1％ ～81.9％.[结论]噻虫啉对松阿扁叶蜂幼虫均有较好的防治效果,且最佳防治时期为1龄幼虫期.
