黄斑长翅卷叶蛾性信息素腺体的扫描电镜观察

黄斑长翅卷叶蛾性信息素腺体呈背囊状,由半环状体和囊状体两部分组成。在扫描电镜下观察,二者之间有一凹陷沟,且两部分的超微结构很不相同。环状体表面有许多较大波折,且无乳状突起;囊状体是起伏不平的复杂的折皱,有大小不一的乳状突起布满这些折皱。因此,囊状体是性腺体的关键部位。

AN OBSERVAION WITH SCANNING ELECTRON MICROSCOPE ON THE SURFACE OF THE SEX GLAND OF YELLOW TOTRIX

The fine surface structure of the sex gland of the yellow tortrix(Aclers fimbriana Thunberg)was observed by means of a scanning electron microscope.The sex pheromone gland of yellow tortrix show a dorsal-sac shape,and it consists of a half-ring form part and a sac projecture.In the image seen form the scanning electron microscope, the ultrastrutures of these two are quite different.There is a channel between two parts the surface of the half-ring form parts is fully distributed With creases structures,and no nipple structure.The sac projecture is covered by com- plicated creases and a lot of nipple structures in it.which are in much different size.Hence,the sac projecture is the key part of sex gland.
