白蜡虫Ericerus pela Chavannes雄虫蜡腺的研究

研究了与虫蜡生产关系密切的二龄雄幼虫蜡腺的发育.发现背腺分批发育现象明显,腹腺发育较同步.泌蜡活动与蜡腺发育有关:第一次泌蜡盛期是多数背腺同时成熟、分泌的结果;第二次泌蜡盛期与蜡腺的生理状态有关,绛色细胞可能起着重要作用.

STUDY ON_THE WAX GLANDS IN THE MALE WHITE -WAX SCALE,ERICERUS PELA CHAVANNES

Ericerus pela Chavannes is an important in insect in China. The male larvae are able to secrete a white wax of great economic value by their integumentary wax glands.The second inslar stage is the most impoitant in the wax production, so the development of the wax gland in this stage was mainly investigated. It was found that throughout all this stage the tergal wax glands grow in turn and the sternal wax glands grow homochroneously comparatively. In this stage there are two periods in which secretion bursts greatly. Just before the first period most of the tergal wax glands grow rapidly and then the first higher secretion presents. And in the second ligher secretion period there are fower wax glands which grow later but more oenocytes around some wax glands, probably the oenoeytes play an important role in the biosynthesis of wax. The results suggest that wax secretion activity depend upon the development of the wax glands. The rational proposal in the wax production was presented.
