摘要 首次应用扫描电镜技术对冠状冠环线虫(Coronocyclus coronatus)、大唇片冠环线虫(C.labiatus)和小唇片冠环线虫(C.labratus)的体表结构特征进行观察和比较。结果表明,3种线虫的形态特征存在明显差异。冠状冠环线虫外叶冠由22个小叶组成;4个亚中乳突起自口领基部,向口领顶部延伸呈隆起状;雄虫生殖锥背唇上有1对卵圆形结构的附属物,中部相融合,上面分布着许多刚毛状突起;雌虫尾部直。大唇片冠环线虫外叶冠小叶19个;口领内上缘在背腹面和侧面向内延伸形成4个大的唇形结构,每个唇片的基部中央伸出1个亚中乳突;雄虫生殖锥背唇上约分布着10个大小不等的圆锥形附属物;雌虫尾部稍弯向背侧。小唇片冠环线虫外叶冠小叶18个;口领内上缘在背腹面和侧面向内延伸形成4个小的唇形结构,每个唇片的基部中央伸出1个亚中乳突;雄虫生殖锥背唇上有1个两端呈卵圆的月牙形附属物;雌虫尾部直。
