Abstract

Morphological comparisons with light microscopy and scanning electron microscopy were made among second-stage juveniles (J2) and males of several isolates of the three subspecies of the tobacco cyst nematode complex, Globodera tabacum sspp. tabacum, virginiae, and solanacearum. Observations focused on the anterior region, (including head shape, lip pattern, and stylet morphology) and the tail region (including tail shape in J2 and spicules in males). The three subspecies could not be separated on the basis of any of these characters.

摘要

利用光学显微镜和扫描电子显微镜,对烟草孢囊线虫复合体(Globodera tabacum)三个亚种(普通烟草孢囊线虫、弗吉尼亚烟草孢囊线虫和茄科烟草孢囊线虫)的几个分离株的二期幼虫(J2)和雄虫进行了形态学比较。观察重点为前部区域(包括头部形状、唇纹和口针形态)和尾部区域(包括J2的尾部形状和雄虫的交合刺)。根据这些特征中的任何一项,都无法区分这三个亚种。
