ABSTRACT: The morphology and histology of the accessory glands of adult male Zonocerus variegatus
Linnaeus) at different ages were described. The accessory glands consist of eleven pairs of slender tubules and five accessory gland types were identified. The glands comprised the basement membrane and an epithelial layer. As the insect aged, the cells of the epithelial layer decreased in height and the diameter of its lumen increased simultaneously suggesting an apocrine mode of secretion.
