Abstract:Abstract: The structures of the spermatheca in 6th-instar nymphs, unmated and mated females of Deracantha onos Pallas (Orthoptera: Tettigoniidae) were investigated by light and scanning electron microscopy. The results showed that epithelial cells of the 6th-instar nymphs were undergoing proliferation, and their morphology was not easy to identify. The preliminary differentiation of the epithelial cells could be seen in the unmated adults, but their distribution was not obvious. The granules occurred in the apical cytoplasm of the epithelial layer. In the spermatheca of mated adults, the differentiated cells formed three types of epithelial cells distributed in distinctive layers, and the granules, which appeared in unmated adults, disappeared. The secretory cavities of glandular cells had polymorphism. Furthermore, on the internal surface of the spermatheca from mated females, the shapes of the bristles and the openings of secretory duct were regionally distributed. It is suggested that mating activity may induce glandular cells to produce large amount of secretions. The bristles and glandular cells in varied regions may play different roles and functions in insects.
