摘要
从江苏省常州地区一苗圃地采集的24种园林苗木根及根际土壤共72份样品中,根据形态特征和测量值共鉴定出根际寄生线虫3属6种,即不确定矮化线虫Tylenchorhynchus dubius(But-schli,1873)Filipjev,1936,有头矮化线虫Tylenchorhynchus capitatus Allen,1955,同形真滑刃线虫Aphelenchus isomerus Anderson&Hooper,1980,燕麦真滑刃线虫Aphelenchus avenae Bastian,1865,辣椒丝尾垫刃线虫Filenchus capsici Xie&Feng,1996和沼泽丝尾垫刃线虫Filenchus uliginosus(Brzeski,1963)Siddiqi,1986。有头矮化线虫和同形真滑刃线虫的寄主均达14种,辣椒丝尾垫刃线虫和沼泽丝尾垫刃线虫的寄主均为10种,燕麦真滑刃线虫、不确定矮化线虫的寄主分别为7和5种。其中不确定矮化线虫、有头矮化线虫、辣椒丝尾垫刃线虫和沼泽丝尾垫刃线虫均为江苏省新记录种。
Isolation and species identification of the rhizosphere parasitic nematodes were made from 72 soil samples and 24 species of garden plant seedlings in Changzhou area of Jiangsu Province. The results showed according to morphological characteristics and measurement,6 species of nematodes belonging to 3 genera, i e. Tylenchorhynchus dubius （ Butschli, 1873 ） Filipjev, 1936, Tylenchorhynchus capitatus Allen, 1955 ,Aphelenchus isomerus（ Anderson＆I-looper, 1980 ,Aphelenchus avenae Bastian, 1865, Filen- chus capsici Xie ＆ Feng, 1996, Filenchus uliginosus （ Brzeski, 1963 ） Siddiqi, 1986, were identified ~ Both of T. capitatus and A. isomerus had 14 host plants, the number was 10 for A. somerus and F. uliginosus. Besides, A. avenae had 7 hosted plants and T. dubius had 5. Among them, T. dubius, T. capitatus,F, capsici, F. uliginosus were the new record species in Jiangsu Province.
