The structure of the salivary gland of the dipteran insect Rhynchosciara angelae in a defined stage of the larval development, characterized by the synthesis and storage of secretion product, is described. Observations were made with both Nomarski optics and electron microscopy. Filiform projections extending into the lumen of the gland were observed in the apical portion of the cells. At the basal region junctions, characterized as hemidesmosomes, were observed between the membrane of the cell and the basal lamina. The plasma membrane presents numerous infoldings into the cell increasing considerably the surface area at this region. Throughout the cytoplasm of the gland cells numerous mitochondria, Golgi complexes, microtubules, profiles of endoplasmic reticulum, secretion granules and glycogen granules were observed. Carbohydrates were detected on ultrathin sections by using the periodic acid-silver methenamine and the periodic acid-thiosemicarbazide-silver proteinate techniques.
描述了双翅目昆虫安吉拉巨蚊幼虫发育特定阶段唾液腺的结构，其特征为分泌产物的合成与储存。使用诺马斯基光学显微镜和电子显微镜进行了观察。在细胞顶端部分观察到延伸至腺腔的丝状突起。在细胞基部区域，观察到细胞与基膜之间的连接，其特征为半桥粒。质膜呈现出大量向细胞内的褶皱，显著增加了该区域的表面积。在腺细胞的整个细胞质中，观察到大量线粒体、高尔基体、微管、内质网轮廓、分泌颗粒和糖原颗粒。通过使用高碘酸-银甲胺和高碘酸-硫代半卡巴腙-银蛋白技术在超薄切片上检测到了碳水化合物。
