摘　　要：广东南海口岸从美国进境黑胡桃木(Juglans nigra L.)中截获1种活的昆虫,经鉴定为胡桃木细小蠹(Pityophthorus juglandis Blackman 1928)。胡桃木细小蠹在中国没有分布记录,存在较大传入风险,且该物种及由其携带的真菌(Geosmithia morbida)可使各类胡桃科植物染病致死,对寄主危害很大。本文记述了胡桃木细小蠹的分类地位、分布、鉴定特征及与近似种的检索表、生物学及危害机制,并对其传播途径、防治方法和检疫方法进行了讨论。One insect species was intercepted in the imported Juglans nigra L. from America at Nanhai port in January 2015. It was identified as Pityophthorus juglandis（Blackman 1928）. It was intercepted for the first time in domestic ports in China. Since there was no distribution record of this pest species in China before, there is great risk of introduction. P. juglandis associated with the fungi it carries, Geosmithia morbida, can cause mortality of all kinds of walnuts plants, doing great harm to its hosts. The classification,geographical distribution, identification, the key to the similar species and the pathogenic mechanism were introduced separately in this paper. And the transmission routes, quarantine measures and control measures were also discussed.
