摘　　要：云南木蠹象是云南松的主要蛀干、蛀梢害虫,以幼虫在松树韧皮部和木质部蛀食为害,常常造成主干和侧枝枯死,严重危害的林分可导致成片松树死亡。该虫于2002年5月首次在威宁县云南松飞播林中暴发成灾,导致松树大量死亡。本文采用有害生物风险分析中的综合分析方法对云南木蠹象在贵州发生危害的风险性进行综合评价,结果表明云南木蠹象属中等危险性的林业有害生物。Pissodes yunnanensis Longer Situ et Zhang is a serious trunk and branch borer of Yunnan pine, and it was found recently in Bijie prefecture of Guizhou province. More than 3. 6 million pine trees had been killed by this pest from 2002 to 2005. In this paper, the damage and the risk of the pest were analyzed according to the economic value of the host, the damage extent of the pest and its spread ways. The result showed that the Yunnan pine weevil is a moderate risk pest in Guizhou province.
