光肩星天牛在新疆的风险分析

Risk Analysis of the Occurrence of Anoplophora glabripennis in Xinjiang

光肩星天牛是我国特有的一种毁灭性蛀干害虫,危害大、防治困难,以幼虫钻蛀树木主干,在树体内蛀食长达22~23个月之久,使树木长势衰弱、枯死,使用价值降低。寄主主要包括杨柳科（Salicaeeae）、槭树科（Accraceac）和榆科（Ulmaeeae）等的几十个树种。主要分布在33°—40°N、103°—110°E之间的广大地区,在新疆仅分布于伊宁市、新源县塔勒德镇、巩留县巩留镇、焉耆县大渠乡、和静县、博湖县博湖镇和查干诺尔乡、阿克苏市、新和县,全疆发生总面积为517.67 hm2。应用综合分析法对其扩散蔓延的风险评估结果表明,光肩星天牛是新疆重要的危险性有害生物,其风险值R=2.28,属高度危险性有害生物。

Anoplophora glabripennis was an endemic pest insect in China with huge damage and difficult prevention.It injuries trees by boring the tree trunk with larvae and stays in the trunk for 22 to 23 months,resulting in the trees growing weak,and dead.Its hosts include dozens of species within the families of Salicaeeae,Aceraceae,and Ulmaceae.It occurs in the vast areas between N 33°-40°,and E 103°-110 °.In Xingjiang,it has been found in Yining,Xinyuan,Gongliu,Yanqi,Bohu,Akesu,and Xinhe with an area of 517.67 hm2.The risk analysis showed that A.glabripennis is one of the key pest species in Xinjiang with a risk value R=2.28,belonging to high risk pest.
