摘　　要：青杨脊虎天牛Xylotrechus rusticus L.是东北地区近10多年来严重危害杨树的蛀干害虫之一。该虫主要侵害胸径20 cm以上的大树主干,幼虫呈环割状危害,极易造成主干风折。本文首次对青杨脊虎天牛的危害特性进行了精细观察和描述,绘制了不同危害阶段的三维坑道结构图,并配以相应的外部危害特征照片,对青杨脊虎天牛的发生监测具有指导作用。The grey tiger longhorned beetle （Xylotrechus rusticus L.） is one of the most serious insect pests of poplar in northeastern China in recent years. The beetle mainly infests the trunk of trees with a DBH over 20 cm.The beetle larvae can ringbark trees thereby increasing the risk of wind damage. We here present the first detailed observations of the damage caused by this beetle. Three dimensional gallery features have been drawn to illustrate different damage stages, and corresponding pictures of bark and phloem are provided to guide monitoring and detection of this pest.
