摘　　要：林间开展了释放管氏肿腿蜂Sclerodermus guani Xiao et Wu和花绒寄甲Dastarcus helophoroides Fairmaire防治松褐天牛Monochamus alternatus Hope试验,结果表明:释放管氏肿腿蜂防治松褐天牛最佳益害比为4∶1,对松褐天牛寄生率达31.25%;释放花绒寄甲卵防治松褐天牛最佳益害比为8∶1,对松褐天牛寄生率达62.77%;释放花绒寄甲成虫最佳益害比为1∶1,对松褐天牛寄生率达70.69%。天敌释放区诱捕器诱捕到的松褐天牛成虫明显少于对照区。The author released Sclerodermus guani and Dastarcus helophoroides to control the pine saw-yer beetle in Huaxi forest park of Yiwu. The results showed that the optimum enemy-pest ratio of releasing S. guani was 4∶ 1,its parasitism rate to larva of Monochamus alternatus reached 31. 25%; the optimum ratio of releasing D. helophoroides eggs was 8 ∶ 1 with parasitism rate to pupa of the pest being62. 77%,and the optimum ratio of releasing D. helophoroides adults was 1 ∶ 1 with average parasitism being 70. 69 %. The trapped number of M. alternatus adults in releasing area was obviously less than that in contrast area.
