光肩星天牛在三江平原地区的分布及风险分析

Distribution and risk analysis of Anoplophora glabripennis(Coleoptera:Cerambycidae)in Sanjiang Plain Area,Heilongjiang Province

光肩星天牛Anoplophora glabripennis(Motsch.)是重要的检疫性蛀干害虫,由于虫态隐蔽,繁殖扩散力强,每年都会造成大量苗木损毁。本文参照国内有害生物危险性评价方法,结合光肩星天牛在黑龙江省三江平原地区分布及危害的调查数据进行了定性和定量分析,得出风险性R值为1.95,属于中度危险的林业有害生物,对其风险性作出综合评价,并提出相应的风险管理策略。

Anoptophora glabripennis ( Motsch.) is an important quarantine trunk borer.Because of its concealed habitas and strong reproductive capacity,it caused a large number of seedlings damaged every year.In this paper,the data of the investigation on the distribution and hazard in Sanjiang Plain Area in Heilongjiang province were analyzed both qualitatively and quantitatively by the domestic method of hazardous biological risk assessment.The risk value R was 1.95,which meant Anoptophora glabripennis( Motsch.) was a moderate risk pest.The risk of the pest in Sanjiang plain area was comprehensively evaluated,and the corresponding risk management strategies were put forward.
