Postembryonic development of Bursaphelenchus mucronatus has been studied. First molt takes place within the egg-shell, and three subsequent molts after hatching. Structure of all juvenile stages are described, as well as molting juveniles and adults. Juvenile stages differ in genital primordium structure, copulatory structures primordial and the body length. In juveniles of 3rd and 4th stage the sex of juvenile was distinguished: male juveniles have cloacal primordium, whereas female juveniles have vulval primordium. Adults differ from juveniles in presence of vulva in females and spicules in males. The key to identify juvenile stages and their sex is given. Male has the terminal bursal flap and 3 pairs of iail papillae: p1 anadanal; p2 and p3 at the bursal flap base: p2 close to mid-line of the ventral body surface, p3 located laterally to p2 at the same level. Unpaired papilla is present on the upper cloacal lip, on the ventral mid-line.
对短尾滑刃线虫的胚后发育进行了研究。第一次蜕皮发生在卵壳内,孵化后还有三次蜕皮。描述了所有幼虫阶段以及正在蜕皮的幼虫和成虫的结构。幼虫阶段在生殖原基结构、交配结构原基和体长方面存在差异。在第三和第四阶段的幼虫中,可以区分幼虫的性别:雄性幼虫有泄殖腔原基,而雌性幼虫有阴门原基。成虫与幼虫的区别在于雌性有阴门,雄性有交合刺。给出了识别幼虫阶段及其性别的关键。雄性有末端尾囊瓣和3对尾乳突:p1位于肛门上方;p2和p3在尾囊瓣基部:p2靠近腹面中线,p3位于p2同一水平的外侧。不成对的乳突位于泄殖腔上唇的腹面中线。
