-We investigated the morphology and ultrastructure of the mucus glands of Apis mellifera drones, which represent a peculiar type of male accessory gland. The three different parts of the mucus glands (muscle layer, gland epithelium and lumen) change with respect to age in the distal and the proximal parts. The thickness of musculature and gland epithelium is larger at the proximal part than at the distal part, where the diameter of the lumen is larger. The secretory cells of the epithelium reach their maximum activity during the first days of adult life, which results in a maximally filled gland lumen by the age of 6 days. The mucus glands represent a unique situation as they are of mesodermal origin, whereas the majority of exocrine glands are ectodermal. morphology / mucus gland / Apis mellifera / drone

“…The thick epithelium in the accessory gland, together with the ultrastructural features of the epithelial cells (omnipresent RER), clearly indicates that there is a high secretory activity. The cytoplasm of the accessory glands of the medfly, Ceratitis capitata, also displays a large amount of RER, which is in agreement with the presence of the proteins in the secretion (Marchini et al, 2003).…”

The morphology and ultrastructure of testes and accessory glands along with the characterization of their secretions were investigated for a braconid species Cotesia vestalis (Hymenoptera: Braconidae) using light and electron microscopes. The male internal reproductive system of this species is distinguished by a pair of testes, one vas deferens, and a pair of male accessory glands. The testes are separate, and the accessory glands are oval and not fused. It was observed that the secretory cells of testes have characteristic smooth and rough endoplasmic reticulum, and that the cytoplasm is filled with an array of granule droplets usually of two to three types. The secretory cells in the case of accessory glands are typified by the presence of microvilli on their apical cell surfaces and numerous mitochondria in their cytoplasm. SDS-PAGE profile when performed depicted a similarity in most bands of the secretions from both testes and accessory glands, except for four proteins of which two were present only in testes, while the other two only appeared in accessory glands. Their molecular weights were 117 and 55 kDa for testes and 196 and 30 kDa for accessory glands, respectively. This study gives new insights into the intriguing features of male internal reproductive system and it especially constitutes the first report of its kind about the secretion properties of these organs in C. vestalis.

“…Our results demonstrate that the epithelium of Anophelinae glands has type 3 organization (Noirot and Quennedey, 1974) with secretory and duct-forming cells, like in ectodermal glands of other insects (Kaulenas, 1992;Dallai et al, 1996;Marchini et al, 2003). The roundish receiving canal of the ductule, never hitherto described in Culicidae, is perforated by a reticular complex that could have a filter role, controlling the release of fluid secretions into the lumen of the accessory gland duct (Quennedey, 1998).…”
