摘　　要：2003～2006年,对云南省主要石榴产区蒙自县、会泽县和建水县的石榴寄生线虫进行了采样调查,根据形态特征进行鉴定。结果表明,危害云南石榴的矮化线虫主要有2种：厚尾矮化线虫（Tylenchorhychus crassicaudatu sWilliams,1960）和克莱顿矮化线虫（Tylenchorhychus claytoniSteiner,1937）,石榴是这2种矮化线虫的新记录寄主。During 2003-2006, the investigation of megranate parasitic nematodes has been conducted, the soil samples were collected from Mengzi megranate garden, Mengzi County and Huize megranate garden, Huize County as well as Jianshui megranate garden, Jianshui County in Yunnan Province. All the soil was sampled from the rhizosphere of Megranate. Nematodes were identified by means of morphological characteristics. The results showed that there were two species of Tylenchorhychus parasitism on the root of megranate in Yunnan： one of which was Tylenchorhychus crassicaudatus Williams, 1960; the other one was Tylenchorhychus clayloni Steiner,1937. Megranate is a new hostplant for this two pests in China.
