摘　　要：在光镜结构研究的基础上,用电子显微镜观察了白蜡虫Ericerus pela Chavannes二龄雄幼虫蜡腺的超微结构和虫体表面的蜡孔及蜡丝形态。重点研究了蜡腺各组成部分的形态特点。The ultrastructure of the wax gland in the male second instar larvae of the white-wax insect, Ericerus pela Chavannes, is investigated. The wax gland is composed of six to eight cells, one main cell, three to five accessory cells, two ductule cells and a secreting canal system. The secreting canal system consists of a duct, a ductuli, an end apparatus, a reservoir, subcu-ticular spaces and collecting canals. The wax gland cells arc of general organization characteristics of integumentary glands. They are charred by a very large quantity of smooth endoplasmic reticulum which forms dense zones throughout the cytoplasm and by a lot of mitochondria which often gathers in certain area. Near the collecting canals the dictyosomes are especially numerous. In different physiological states the regularly morphological modification of smooth endoplasmic reticuluni and mitochondria takes place during a day. Unlike that of general integumentary glands, the end apparatus of this wax gland has several cavities which are formed with the ductule terminate branched. The end apparatus is of only a fibrillar layer instead of two layers. The fibrillar is composed of fibrils. Its diameter is larger than usual. All of these characters make secretory products go out easily.
