摘  要:
青岛市二球悬铃木受根结线虫严重为害。该线虫会阴花纹近圆形,条纹密致,近侧线处条纹呈“Z”字形,甚至卷曲;口针长17μm,基部球与针杆分离,呈球形;只能侵染烟草、番茄和西瓜,在辣椒上形成根结甚少,不能侵害棉花和花生。这些特征与Hedwig Hirschmann(1982)描述的美国梧桐上的根结线虫一致。鉴定青岛二球悬铃木根结线虫为Meloidogyne platani Hirschmann。该种在我国尚属首次报道。

摘  要:
Root-knot nematodes are serious on the London planetree in Qingdao. Perineal pattern of this nematode has fine close spaces, the whole pattern appears much round and striae in dorso and ventro lateral areas are slightly wavy and show a zig-zag curve. Stylet length is I7μm, stylet robust distinctly sets off from shaft , Among the host differentials , tobacco , tomato and watermelon can be greatly affected while pepper is lightly galled. No infection has been foud on peanut and cotton. These characteristics have the similarty of Meloidogyne platani in the description of root- knot nematode on American planetree made by Hedwig Hirschmann in 1982. So we have identified that root-knot nematode of London planetree in Qingdao belongs to Meloidogyne plantani Hirschmann.
