摘　　要：双条杉天牛(Semanotus bifasciatus Motschulsky)属鞘翅目(Coleoptera)天牛科(Cerambycidae),是柏科树木上毁灭性蛀干害虫之一。该天牛主要以幼虫危害侧柏、杜松、圆柏等常绿树种,已经给我国很多地区造成了严重的经济和生态损失。目前双条杉天牛已在陕西部分地区危害,为了明确双条杉天牛在陕西省的风险等级,以制定相应管理对策。本研究依据原国家林业局林业有害生物风险分析指标体系及赋分标准,对双条杉天牛在陕西省的风险性进行了综合评估分析。结果表明:双条杉天牛在陕西的风险综合评价值R=2.28,该天牛在陕西省属于高度危险性有害生物。针对双条杉天牛在陕西省的高度危险性,提出了加强检疫、全面普查监测、实施分区防治和加强疫区治理的管理措施。本研究为陕西控制和管理该有害生物提供了基础资料和理论依据。Semanotus bifasciatus Motschulsky(Coleoptera:Cerambycidae) is one of destructive wood bores on Cupressaceae trees. This beetle attacks evergreen tree species,such as Platycladus orientalis,Sabina chinensis,Juniperus rigida,and causes serious economic and ecological damage in many parts of China. At present,it was found in some parts of Shaanxi Province. In order to clear the risk level of the S. bifasiatus and develop scientific management countermeasures in Shaanxi Province,the risk analysis of this beetle was comprehensively evaluated and analyzed by the forest pest risk analysis index system and standard of natural endowments of state forestry administration. The result showed that the comprehensive evaluation risk(R) values of S. bifasiatus was 2.28 belonging to highly dangerous species in Shaanxi Province. In view of the high risk of this beetle,management measures such as strengthening quarantine,comprehensive monitoring,implementing division treatment and strengthening infested area management were proposed. This research provided basic data and theoretical basis for controlling and managing of this pest in Shaanxi Province.
