摘　　要：从2014年10月至2015年2月到蒙自市文澜落龙庄、草坝营房、草坝六村、草坝十七村等葡萄地进行实地调查,采用五点取样法,选取地上部分生长势弱、叶发黄或根部出现变褐萎蔫等症状的植株,采取其根际周围2 kg的土样,共采集28份土样。通过形态鉴定的方法,对蒙自葡萄根际土壤寄生线虫的种类进行初步鉴定,通过实验初步鉴定出葡萄寄生线虫3属4种,分别是燕麦真滑刃线虫(Aphelenchus avenae Bastian,1865)、肾状肾形线虫(Rotylenchulus reniformis Linford et Oliverira,1940)、双宫螺旋线虫[Helicotylenchus dihytera(Cobb,1893)Sher,1961]、假强壮螺旋线虫[Helicotylenchus pseudorobustus(Steiner,1914)Golden,1956]。From 2014 October to 2015 February, we surveyed the grapes cultivation area in Mengzi Luo Long Zhuang of Wenlan, Yingfang, Liu Cun, Shi Qi Cun of Caoba. The plant appeared leaf potential weak yellow or brown roots were chosen for sampling, Approximatedly, 2 kg rhizosphere from each plant were collected by five point sampling method. In total, 28 soil samples. By the methods of morphological identification, the species of parasitic nematodes in rhizosphere soil of grapes in the preliminary were identified. 3 genera and 4 species of plant parasitic nematodes were identified, A. avenae （ Aphelenchus avenae Bastian, 1865 ）, R. reniformis （Rotylenchulus reniformis Linford et Oliverira, 1940） , H. dihytera [ Helicotylenchus dihytera Sher Cobb, 1893, 1961] , H. pseudorobustus [ Helicotylenchu~ pseudorobustus Golden （Steiner, 1914）, 1956 ].
