摘　　要：台湾坡天牛一般随着木制品及包装制品进行远距离传播入境。目前我国台湾地区和日本有分布,在我国大陆地区尚未见该虫的发生报道。2019年5月凭祥口岸从来自越南的相思木板上截获了台湾坡天牛,为我国大陆首次截获。通过显微形态特征的观察和测量进行台湾坡天牛种类鉴定。台湾坡天牛与近似种的主要区别:其鞘翅基部具明显的黑褐色宽横带。通过入侵可能性分析,来自我国台湾地区、日本的台湾坡天牛入侵我国大陆地区的可能性很大。台湾坡天牛在我国广东、广西、福建等地区定殖和扩散风险很大。一旦传入我国,将对我国的农林安全造成巨大威胁,各口岸应对进境的木制品及包装加强检验检疫。Pterolophia formosana(Coleoptera:Cerambycidae)is a quarantine pest that generally spreads over long distances with wood products and packaging products.It is mainly distributed in Japan and Taiwan,China.So far,there have been no reports of occurrence on China's Mainland.P.formosana was intercepted for the fisrt time in May 2019 at Pingxiang port,on Acacia timber board originating from Vietnam.The species identification was carried out by observation and measurement of micro-morphological characteristics.The main difference between P.formosana and the similar species is that the base of elytra has distinct dark brown broad transverse band.The analysis of the possibility of invasion indicated that P.formosana from Taiwan,China and Japan had high possibilities to invade China's Mainland.The risk of colonization and spread of P.formosana in Guangdong,Guangxi,and Fujian is very high.Once P.formosana introduced into China,the agricultural and forestry security of China will be greatly threatened.The phytosanitary control of imported wood products and wooden packaging should be strengthened.
