摘　　要：为有效利用花绒寄甲Dastarcus helophoroides防治光肩星天牛Anoplophora glabripennis,在武威绿洲区开展试验研究。通过采用不同释放方式、不同时期、释放不同数量和种源的花绒寄甲,进行防治效果比较。结果表明:直接释放和打孔释放的防治效果无差异;6月初释放的防治寄生率比9月下旬释放的高14.17个百分点;随投放数量的增加防治寄生率呈现上升趋势,投放数量达4头以上时,寄生率增幅趋于平缓;湖南种源和北京种源的花绒寄甲防治寄生率无差异。武威绿洲区利用花绒寄甲防治光肩星天牛,可于6月初按4头/株直接释放花绒寄甲成虫,能达到既节约成本又实现高效防治的目的。In order to effectively use Dastarcus helophoroides to control Anoplophora glabripennis,the experiment was carried out in Wuwei oasis area,and the control effect was compared using different ways,at different periods,with different quantity and provenance.The results showed that there was no difference in control effect between direct release and drilling release.The control parasitism rate of D.helophoroides released in early June was 14.17 percentage point higher than that released in late September.The control parasitism rate increased with the increase of the quantity released,and the increase of parasitism rate tended to be smooth when releasing four individuals or above.There was no difference in the control parasitism rate between the provenances from Hunan and Beijing.Therefore,four D.helophoroides adults could be released per plant in early June to control A.glabripennis in Wuwei oasis area.
