摘　　要：【目的】并蛎蚧属盾蚧科并蛎蚧属,该虫食性杂,危害植物种类多,极易随水果、苗木、景观花卉植物等寄主传播入境。并蛎蚧分布于美国、日本和我国台湾省,在我国大陆地区尚未见该虫的发生报道。2016年5月山西口岸从来自台北的水果释迦上截获了并蛎蚧,为我国大陆首次截获。【方法】通过显微形态特征的观察和测量进行种类鉴定,并研究并蛎蚧的生物学、生态学相关资料,对其进行风险评估。【结果】并蛎蚧与近似种的主要区别:中臀叶与第二臀叶愈合中间有腺刺,有第三对臀叶,中臀叶有向内延伸的硬化区。通过风险评估认为,来自我国台湾、日本的并蛎蚧入侵我国大陆的风险较大。并蛎蚧在大陆亚热带地区的定殖和扩散风险很大。【结论】我国大陆地区的气候条件、植物种类可为并蛎蚧的定殖提供可能的适生条件,各口岸应对进境的并蛎蚧寄主植物加强检验检疫。[Aim] Neopinnaspis harperi Mckenzie is a scale insect in the family of Diaspididae. The insect feeds on various fruits, nursery stocks and flowers. N. harperi is mainly distributed in America, Japan and the island of Taiwan, China, while has never been detected in China's Mainland. N. harperi was intercepted for the first time in May 2016 at Shanxi port, on fruits of cherimoya, Annona squamosa originating from Taipei.[Method] We identified the species by observing and checking the micro-morphological characteristics.[Result] A risk assessment indicates that N. harperi consitutes a high risk of invasion for Chinese subtropical areas.[Conclusion] Once established, N. harperi can easily spread, due to the presence of several host plant species. The phytosanitary control of imported host plants should be strengthened.
