大袋蛾雌虫性信息素腺细胞的超微结构

<正>用透射电镜研究了大袋蛾性信息素腺细胞的超微结构。每个腺细胞具有一个表皮孔和一个由微绒毛围成的端器,但是没有导管细胞,也没有真正的表皮导管。腺细胞上方的表皮显然是由间细胞分泌形成的。腺细胞的分泌物从端器中经表皮孔而排到体外,所以这进一步证实了大袋蛾的性信息素腺细胞是一类新型的昆虫表皮腺细胞。基于各种昆虫表皮腺细胞的形态和功能,还讨论了昆虫表皮腺细胞的可能的进化途径。

ULTRASTRUCTURE OF THE SEX PHEROMONE GLAND CELL OF CLANIA VARIEGATA SNELLEN

The ultrastructure of the sex pheromone of Clania variegata was examined by use of the transmission electron microscope. Each pheromone gland cell has a cuticular pore and an end apparatus, bounded by microvilli, but there is no duct cell, nor real cuticular ductule. The cuticle above the gland cell is obviously produced by the intermediate cell. The secretions of the gland cell are released from the end apparatus through the pore to the exterior of the body. Thus, it has been further confirmed that the sex pheromone gland cell of Clania variegata is a new type of insect epidermal gland cell. Based on morphology and fuctions of all types of insect epidermal gland cells, this paper also discusses their possible ways of evolution.
