摘　　要：2002年3～8月,对甘肃省部分地区蔬菜根际的植物寄生线虫进行了广泛调查,从番茄、辣椒、茄子、黄瓜等的根际土壤样品中共分离鉴定出线虫7个属14个种,包括3种矮化线虫(Tylenchorhynchusclarus,T.mashhoodi,T.aerolatus)、2种节纹线虫(Merliniusbrevidens,M.communium)、3种短体线虫(Pratylenchusne-glectus,P.hexincisus,P.scribneri)、3种丝尾垫刃线虫(Filenchuscylindricollis,F.vulgaris,F.ditissimus)、燕麦真滑刃线虫(Aphelenchusavenae)、双宫螺旋线虫(Helicotylenchusdihystera)、活泼平滑垫刃线虫(Psilenchushilarulus),其中,大多数种类为甘肃省新记录种,优势种为短小节纹线虫。它们广泛分布于甘肃省天水地区的秦城、北道,兰州地区的吊场、刘家堡,河西地区的张掖、民勤,红古区的张家寺,永靖县的太极镇,庆阳,临洮等地,即在东径100°26′～105°45′,北纬34°35′～38°56′,海拔从1142～1895m的温带干旱、半干旱、半干旱半湿润地区均有线虫的寄生和繁殖。A survey of the plant parasitic nematodes on vegetables was carried out in Gansu province in north-west China, from March to August in 2002. The soil samples were collected around the rhizosphere of tomato, capsicum, eggplant, cucumber, etc. Fourteen species of stunt nematodes belonging to 7 genera were identified, including Tylenchorhynchus clarus,T.mashhoodi,T.aerolatus;　Merlinius brevidens, M.communium;Pratylenchus neglectus,　P.hexincisus,　P.scribneri; Filenchus cylindricollis,　F.vulgaris,　F.ditissimus;　Aphelenchus avenae,　H.dihystera and P.hilarulus. Among them,many genera and species had not been reported in Gansu province.They widely parasitized and reproduced in arid, semi-arid and semi-humid in the range of 100°26′～105°45′ E and 34°35′～38°56′ N and the altitude of 1 142～1 895 m, were distributed in Qincheng, Beidao in Tianshui district, Diaochang, Anning in Lanzhou district, Zhangjiasi in Honggu district, Taijizhen in Yongjin county, Qinyang, and Lintao etc.
