摘要
黄斑星天牛和光肩星天牛是陕、甘、宁三省 (区 )防护林的毁灭性害虫 ,在研究了各地多年的防治经验和主要造林树种的抗性表现后 ,得出天牛猖獗的主因是人为营造了大范围的天牛倾性林 ,使生态系失去平衡的结果。建立持续无天牛虫灾生态经济型林是以林业生态体系控制天牛的数量消长 ,是治本的战略 。
Anoplophora nobilisand A.glabripennis are two destructive insect pests occurring in the shelter forests in Shaanxi,Ningxia and Gansu.After studied many years'control expe- riences and resistance of the major forestation species in each area,it is concluded that themain cause of longicorn break is the man made establishment of longicorn susceptible shelter forests,resulting an unbalanced ecosystem.The strategic policy to get at the root of this problem is to establish sustainable shelter forests of economic ecological type without the plague of longicorn by using forestry ecological system to control the number of longicorn, which reflecting the ecological view of integrated management of insect pests.
