Abstract

This study presents the morphology and structure of the rectum in Bolua turkiyae Ünal, 1999 (Orthoptera, Tettigoniidae) using light and scanning electron microscopy. The digestive system in insects is split up three parts as the foregut, the midgut and the hindgut. The rectum is last part of the hindgut. The results show that the rectum of B. turkiyae consists of 6 rectal pads, in similar to rectal pads found in others Orthopteran species. The rectum contains the muscle tissue with connective tissue, epithelial layer with columnar cells, and the cuticular intima from the outside to inside. There is microvillus on the apical side of the columnar cells that serves in water and ion reabsorption.

Keywords
