我国广东湛江、广西合浦红树林首次发现双齿材小蠹Xyleborus bidentatus(Motschulsky,1863).该害虫主要侵害我国红树林优势树种白骨壤Avicennia marina,种群数量很高时,导致枝干或整株枯死.简要介绍该虫的形态特征,并提供形态和危害状照片.该物种侵害对红树林存在潜在风险.解析双齿材小蠹暴发的机制和白骨壤枯死原因是目前亟待解决的问题.
Xyleborus bidentatus(Motschulsky,1863)was first discovered in mangrove ecosystems in Zhanjiang,Guangdong province and Hepu,Guangxi Zhuang Autonomous Region,China.This pest mainly infests Avicennia marina,which is the most important component of mangrove plants in China,likely causing the withering and death of branches or the whole plant when its population is very high.The morphological characteristics of this pest were briefly introduced and photos of its morphology and damage symptoms were provided.This pest has posing a potential risk to mangrove forests.Analyzing the mechanism of the outbreak of X.bidentatus and the direct cause of the death of A.marina is an urgent problem that needs to be solved.
