Özet
In this work, histologic structure of midgut of Melanogryllus desertus was investigated for the first time and some scanning electron microscope photographs were also presented. Two big and large gastric caeca anterolaterally surrounded the midgut. There were microvilli on the surface of columnar epithelial cells arranged as a single layer by forming foldings in the gastric caeca. Gastric glands consisted of cubic epithelial cells arranged as single layer were encircled by connective tissue. Because of the activities of epithelial cells, many secretory granules with different size were observed. There was a peritrophic membrane encircling food in the lumen of midgut. Cells in the basal portion of midgut were clustered and called nidi. Longitudinal and circle muscle layer encircled midgut, respectively. Pyloric valve was located at junction of midgut and hindgut. © Biharean Biologist, Oradea, Romania, 2012.
