Abstract:Since February 1, 2022, pine imports from the United States and Canada can only enter through 17 designated ports such as Jiangsu (Nanjing, Lianyungang), Fujian (Fuzhou) and so on. Due to the complex epidemic situation of imported pine carrying in the United States and Canada, it will bring huge pressure to prevent and control the epidemic at designated ports. Ips avulsus Eichhoff was intercepted for the first time in January 2022 at Lianyungang port, on logs board originating from America. According to literature reports, this specie is not distributed in China. The main difference between I. avulsus and similar species is that the body size is relatively small, generally 2.1-2.8 mm, elytral declivity with four spines per side, spine 2 and spine 3 are born in the common base. The preliminary risk analysis of I.avulsus in China is very high, once I. avulsus introduced into China, the forestry security of China will be greatly threatened. So the relevant designated ports should strengthen the quarantine of imported logs from North America.
