Abstract: The author used polyacrylamide gel electrophoresis method to compare the esterase isozymes of 47 isolates of 5 Meloidogyne spp.originated from 14 provinces (cities) in China.Some factors which maybe affect enzyme phenotypes were also studied.The result showed that the esterase phenotypes of egg-laying female were evident,stable and species specific.It was stable intro species too.Comparison of studies on inoculated plants,origin of isolates,physiological races,culture in greenhouse and from plants inffected naturally,different nutritions etc.showed that all of them didn't affect the species specific phenotypes.So the esterase phenotypes could be used as a taxonomic criteria.Since the phenotypes were not the same in different developmental stages for the same species,it was suggested that use of egg-laying females for identification is simple and reliable.
