摘　　要：杨树是杨柳科（Salicaceae）中杨属（Populus）植物落叶乔木的统称,是重要的速生树种之一,杨树产业在苏北地区是重要的支柱产业。植物寄生线虫是重要的病原物之一,其分布广泛,几乎每一种栽培植物都受线虫寄生,杨树在生长发育过程中也必然受到线虫的寄生和为害。为了解线虫对杨树的危害性,首先要对杨树寄生线虫种类展开调查,课题组前期已在江苏省2个地区进行了初步调查,调查范围有限（怀意君等,2010）。为了明确寄生江苏省杨树的主要线虫种类,此次选择在更广的范围内对江苏省杨树寄生线虫进行调查鉴定。下面就鉴定结果中的垫刃目（Tylenchida）和矛线目（Dorylaimida）线虫进行报道。Five species of Tylenchida nematodes and two species of Dorylaimida nematodes were identified in 54 samples collected in roots and rhizosphere soil of poplar trees from Zhenjiang, Yangzhou, Huaian, Lianyungang, Suzhou and Wuxi city of Jiangsu Province from June to November in 2008. These species included Filenchus orbus, Filenchus vulgaris, Tylenchorhynchus brassicae, Helicotylenchus digitiformis, Scutellonema brachyurus, Xiphinema americanum and Xiphinema hunaniense. Among those nematodes, Filenchus vulgaris was new records in Jiangsu Province, and the poplar tree was new host of Filenchus vulgaris, Tylenchorhynchus brassicae and Xiphinema hunaniense.
