香蕉上的新纪录雪松毛刺线虫描述

Description of Trichodorus cedarus,a new record on banana

本文对中国云南河口香蕉上的雪松毛刺线虫(Trichodorus cedarus Yokoo)的形态特征进行了描述,其测计值与我国文献记载的杉木、桃、苹果和梨树种群相关测计值比较,香蕉种群的雌雄虫虫体平均长度和b值偏大,口针平均长度较杉木和桃上种群的短,长于苹果和梨树上的种群。该线虫在香蕉根围土发现尚属首次。

A new record species on banana from Hekou of Yunnan Province in China, Trichodorus cedarus Yok- oo, was described. Compared with the measurements in literatures, the average body length of the trichodorids on banana was longer than those of other specimens in China. The average onchiostyle length was shorter than those on peach and fir, but longer than those on pear and apple.
