摘    要:对小木蠹蛾Holcocerus insularis雌蛾性信息素分泌腺提取物的触角电位(EAG)、毛细管气相色谱 (GC) 的测定以及对腺体位置和形态结构的扫描电镜、透视电镜观察。结果表明,小木蠹蛾性信息素分泌腺是一个由节间膜特化而成的上皮结构,位于腹部末端8~9节之间,为一个可外翻的腹褶,表面分布着饱满的锥形体。羽化后2天未交尾的雌蛾腺体细胞呈单层排列,腹面中央由密集的柱形细胞组成,向两侧延伸至背部,细胞由柱形逐渐变为扁平形,细胞核为椭圆形。细胞基底膜基褶较多,质膜上分布着微绒毛,并与内表皮连接,内表皮上有多层几丁质,细胞质中含有空泡、线粒体、脂质粒及光面内质网。

关 键 词:小木蠹蛾  性信息素分泌腺  组织学

Abstract:The location and histology of the sex pheromone producing gland in female Holcocerus insularis was studied by measuring electroantennogram (EAG) and gas chromatography(GC) of female sex pheromone extracts and by scanning electron (SEM) and transmission electron microscopy (TEM). This study showed that the gland is an eversible fold situated ventrally in the modified intersegmental membrane between the eighth and ninth abdominal segments. Many plump cones occur on the surface of the gland. The glandular cells of 2 day old virgin female moths are arranged in one layer, among which the central cells are columnar and the nucleus elliptical. There is evident conjugation between cells and the involution is more in the basal membrane of each cell. Microvilli are distributed on the cytoplasmic membrane and linked with endocuticle on which there are many layers of chitin. The outer cuticule is stained deeper. The cells contain bubbles, mitochondria, glycogen deposits and rough and smooth endoplasmic reticulum. It is suggested that the development of sex pheromone producing cells is synchronized with the growth and maturity of female moths.
Keywords:Holcocerus insularis  sex pheromone  producing gland  histology
