【摘要】 应用扫描电镜对广州血管圆线虫的成虫进行了全面观察。该虫头部顶面有一个口腔,周围有两圈感觉乳突,每圈6个,但外圈的已退化而不很明显。在内圈侧乳突的外侧,有一对头感器开口。体壁表面有环状横纹,两横纹间有纵行皱襞。雄虫尾部两根交合刺的形态结构明显不同,根据其形态特征,我们分别称之为管状交合刺及槽状交合刺。当管状交合刺被包于槽状交合刺中时,外观似为一根:而当其从槽中脱出时,则外观为两根。此外,对雄虫的交合伞及雌虫尾部的结构也进行了描述。更多还原

【Abstract】 Scanning electron microscopic observations were made on adult Angiostrongylus can-tonensis, The apex of the head has a round mouth with two rows of 6 sensory papillae each around it. The papillae of the outer row are more rudimentary and inconspicuous. A pair of amphidial pores are visible on the external side of lateral papillae of the inner row. The surface of the body is covered with a circular striated cuticle and short lon-gitudinal ridges lying between two circular cuticles. The two copulatory spicules at the posterior end of male worms are obviously different in morphology. According to their morphological characteristics, we named them "tube-like" copulatory spicule and"grooves-like" copulatory spicule. The former, when enclosed in the latter, appeared as a single one. The copulatory bursa of the males and the structures of the tail part of the female are also described (Figs.l-18).更多还原
