粗壮六索线虫 Hexamermis arsenoideaHagmeier,为线虫网(Nematoda),咀刺目(Enoplida),索总科(Mermithoidea),索科(Mermithidae),六索为(Hexamermis)。分布在辽宁省东部山区,是柞蚕主要寄生线虫之一,严重地影响柞蚕茧的生产。但是,它也寄生多种鳞翅目昆虫的幼虫,对控制害虫的发生起到一定作用,因此亦是农林害虫的重要天敌。1973～1981年,我们在防治柞蚕线虫病工作的同时,对粗壮六索线虫的一些生物学特性进行了观察,现将结果概要报道如下。一、形态概述成虫:乳白色,体长且粗,呈圆筒状,角皮厚,有明显的交叉纤维。头部细,尾部粗。头圆形,食道长而粗。神经环呈亚铃形,中部横贯一束粗大的神经纤维。头乳突6个,左右
Hexamermis arsenoidea Hagmeier, Nematoda, Enoplida, Mermithoidea, Mermithidae, Hexamermis. Distributed in the eastern mountains of Liaoning Province, is one of the main parasitic nematodes tussah, seriously affecting the tussah cocoon production. However, it also parasites larvae of various lepidopteran insects and plays a role in controlling the occurrence of pests and is therefore also an important natural enemy of pests of agriculture and forestry. From 1973 to 1981, while controlling the tussah nematode disease, we observed some biological characteristics of the robust C. elegans, and the results are summarized as follows. First, the morphological overview Adult: milky white, body length and thick, cylindrical, horn thick, with obvious cross-fiber. Fine head, thick tail. Round head, esophagus long and thick. Nerve ring was sub-bell-shaped, the middle of a bundle of thick nerve fibers. 6 mastoid process, so
