摘　　要：花绒寄甲是寄生天牛的重要林木天敌昆虫,为了解花绒寄甲在林间的寄生防治效果,通过林间释放花绒寄甲(成虫、卵卡)来寄生松褐天牛,根据松褐天牛被寄生率和虫口减退率,研究花绒寄甲对松褐天牛的防治效果。结果显示,2019年校正虫口减退率平均值为46.20%,寄生率高于50%的占66.7%;2020年防治效果为33.18%,寄生率为34.91%,由此可见,释放花绒寄甲对松林松褐天牛防治效果较明显,寄生情况良好,治理区域内松褐天牛数量有所减少,对松褐天牛危害区具有较好的种群抑制效果。Dastarcus helophoroides is an important natural enemy of longicorn.In order to know that the control effect of parasitism of D.helophoroides,we breeded D.helophoroides when they were babies,which are advantageous to monochamus alternatus'parasitism.According to the parasitism rate and the rate of degeneration of M.alternatus,the control effect of the D.helophoroides on M.alternatus was studied.The results showed that the average population reduction rate in 2019 was 46.20%,and 66.7%had a parasitic rate higher than 50%;in 2020,the control effect was 33.18%,and the parasitism rate was 34.91%.It can be seen that the release of D.helophoroides has obvious control effect on M.alternatus in the pine forest,the parasitism is good,the number of M.alternatus in the treatment area has been reduced,and the control effect of M.alternatus is generally better.
