本文描述了华支睾吸虫、红纹夜蛾、球形头纹夜蛾、褐纹夜蛾、黑腹隐尾轮虫、昆虫病原甲虫和杜贾迪尼轮虫的感染性三期幼虫的形态。所研究的幼虫的鞘结构似乎与Rhabdiasidae科其他物种中描述的相似，其格子状外观是由外部纵向条纹和内部纵向和横向脊的组合造成的。幼虫在形态上基本相似，但在有无前尖突(伪裂)、尾尖的形状和纹饰以及尾部侧翼的结构等方面有所不同。未观察到研究种幼虫的形态特征与其分类位置或成虫对特定寄主群的专一性之间的关系。无论如何，每个物种的幼虫都可以通过身体前部和尾部的形态特征来识别。
The morphology of infective third-stage larvae of Rhabdias bufonis, R. rubrovenosa, R. sphaerocephala, R. fuscovenosa, R. elaphe, Entomelas entomelas and E. dujardini is described. The sheath structure in the studied larvae appeared to be similar to that described in other species of the family Rhabdiasidae, its chequered aspect being caused by a combination of outer longitudinal striations and inner longitudinal as well as transverse ridges. The larvae were similar in general morphology but differed in the presence/absence of anterior apical protuberances (pseudolabia), the shape and ornamentation of the tail tip, and the structure of lateral alae in the caudal region of the body. No relationship between the morphological characters of the larvae of the studied species and their taxonomic position or specificity of adult parasites to a particular host group was observed. Regardless, the larvae of each species can be identified by a combination of morphological peculiarities in the anterior and caudal regions of the body.
