1995年,在我国云南省路南县发现了根结线虫的一种未见报道的酯酶谱带类型,分别为0.47和0.59,与以往报道的爪哇根结线虫酯酶谱带类型J3相比缺少 Rf 值为0.55的谱带;结合形态特征和鉴别寄主试验结果,将这种根结线虫鉴定为爪哇根结线虫,将其酯酶谱带类型称为J2型。讨论了爪哇根结线虫是否有种下分类的可能。

In 1995 , a new esterase phenotype was found in a population of Meloidogyne javanica infecting tobacco in Lunan County of Yunnan Province , and the Rf value is 0. 47 and 0. 59 respectively. Morphological characters and differential host test suggested that the population belongs to M. javanica. However , the esterase phenotype was found to be different from that of M. javanica reported so far to absent a band ( Rf = 0. 55) . The new esterase phenotype is here designated as J2 for M. javanica. The possibility of a subspecies identity to accommodate the population with the new esterase phenotype is discussed.
