摘　　要：对韩国进境的一批松木包装检疫时,发现一种滑刃属线虫种群。其形态特征与柳滑刃线虫[(Aphelenchoides salixae)]近似,核糖体28S基因D2-D3区序列与GenBank中该种线虫的相似度高达100%,系统进化树显示木包装截获的线虫种群均与柳滑刃线虫种群聚在一个分支上,鉴定为柳滑刃线虫。该线虫2017在伊朗被首次发现,并于伊朗其他省份被发现报道,在其他国家未见报道。这是我国首次截获该线虫。During the quarantine of a batch of pine packaging wood imported from South Korea,a popu-lation of nematodes belonging to the genus Aphelenchoides was detected.Based on its morphological char-acteristics,it is similar to the Aphelenchoides salixae,and the ribosomal 28S D2-D3 region sequences is iden-tical to A.salixae sequences submitted in the GenBank.The phylogenetic tree shows that the nematode population intercepted from packaging wood is clustered on one branch with A.salixae.It was identified as A salixae.The nematode was first discovered in Iran in 2017 and has been reported in other provinces of Iran,but has not been reported in other countries.This is the first time that China has intercepted this nematode.
