摘 要:杨二尾舟蛾以幼虫取食树木叶片为害,近年来在西藏地区也时有发生记录。为科学评估该虫害在西藏的蔓延风险,在首次西藏普查的基础上,采用综合分析法对杨二尾舟蛾的分布范围、潜在危害性、寄主植物的经济重要性、传播扩散的可能性以及风险管理难度进行定性和定量分析,确定其危险等级。结果表明,杨二尾舟蛾在西藏地区的风险性值R=1.79,属于中度危险有害生物,应予以重点关注和治理。Cerura menciana Moore larvae feeds on tree leaves, it has also been recorded in Tibet in recent years. To assess the spread risk of the pests, qualitative and quantitative analysis were carried out on the risk of Cerura menciana Moore from the follow aspects on basis of the first census: distribution of the pests, potential harmfulness, economic importance of host plants, possibility of the peststransmission and the difficulty of management. The riskanalysis showed that Cerura menciana Moore was belonging to medium risk pest in Tibet with a risk value R=1.79, so the pest should be given priority attention and governance in the future..
