| 中文摘要: |
| 以天敌昆虫花绒寄甲为研究对象，在北京市内房山区和大兴区道路两旁受危害的旱柳释放花绒寄甲卵，40多天后对防治效果进行调查。结果表明:当年释放卵卡对天牛幼虫致死率最高达到 79.17%；取回受害枝做树木解析，调查受害木虫口减少量最高为 100%。当年释放花绒寄甲卵对光肩星天牛幼虫控制效果明显，且逐年累计释放花绒寄甲能够有效地控制天牛幼虫的发生。 |
| 英文摘要: |
| Dastarcus helophoroides, the natural enemy insect of Anoplophora glabripennis, was released in Fangshan District and Daxing District of Beijing. The control effect has been investigated for more than 40 days. The results show that the highest annual mortality rate of Anoplophora glabripennis's larvae on Salix matsudana protected by the released eggs of Dastarcus helophoroides is up to 79.17%. According to the investigated data on the injured tree's branches of Salix matsudana, the highest accumulated mortality rate of Anoplophora glabripennis's larvae is up to 100%. So, the Anoplophora glabripennis larvae could be effectively controlled by releasing the eggs of D. helophoroides. |
