摘　　要：2007-2009年期间,对浙江省不同地区蔬菜上根结线虫样本进行广泛采集、调查及种群形态学鉴定.根据雌虫会阴花纹、2龄幼虫和雄虫的相关测量值等主要形态学鉴定特征,鉴定出2种根结线虫:南方根结线虫(Meloidogyneincognita)和爪哇根结线虫(M.javanica),其中,南方根结线虫在浙江省为优势种群,分布广泛;爪哇根结线虫首次在温州发现.During 2007 to 2009,an extensive survey and morphological identification on root-knot nematodes,Meloidogyne spp.,occurring in vegetable crops of Zhejiang,China,were carried out.Based on diagnostic characters and morphometrics of females,males,and second-stage juveniles,especially the perineal patterns of female,two species were identified,i.e.M.incognita and M.javanica,in which M.incognita was the preponderant species,widely distributed in vegetable crops of Zhejiang,whereas M.javanica was only found in Wenzhou of Zhejiang,and this was the first record of the species in Zhejiang.
