– 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(More)
The bulbus is a part of the unique functional penis (endophallus) in the genus Apis and was studied in Apis mellifera drones. The bulbus consists of a thin cuticular membrane, covered by four different epithelia (dorsal epithelium, anterior epithelium, ventral epithelium I and ventral epithelium II). One day before eclosion, pupae have no sclerotised plates(More)
The present study documents the pace of accessory gland and testes degeneration in the wasp Vespula vulgaris by means of a histological and metric approach, that has not been carried out for social wasps so far. To a certain extent, comparison is made with the degenerative processes of the mucus glands of the honeybee drone. In V. vulgaris, no generative(More)
