| Abstract | ||
| Identification of hemocytes is one of the basic studies of circulatory system physiology. Blood cells, as the first defense barrier to insect cellular immunity, participate in blocking the foreign particles in the form of phagocytosis and nodules. In the present study, homocytes of adults of Blepharopsis mendica were identified after staining with Gimsa and using a light microscope with a magnification of 40. In the hemolymph of this predatory insect, five types of homocytes were observed, including prohemocytes, granulocytes, plasmotocytes, oenocytoids, and spherulocytes. The most abundant blood cells in the nymphs and adults of this mantis were spherulocytes and plasmotocytes, respectively. The lowest abundance of cells belonged to prohemocytes. Oenocytoids were the largest cells. Oenocytoids had a large nucleus that extended almost to the side of the cell membrane and the cytoplasmic surface of these cells was granular. Prohemocytes were the smallest cells and observed with the distinct central nucleus. Plasmotocytes were observed as spindles, and the common polymorphic profile of most insects hemolymph was not observed in hemolymph of B. mendica. Granulocytes size were small to medium but were larger than prohemocytes with granule–like granules in cytoplasmic surface. Spherulocytes are medium to large, have a central nucleus, and numerous spherul occupy the cytoplasm of these cells. Adult body weight and blood volume were higher than the nymphs of this mantis. So, it is clear that there are higher populations of hemocytes in adults in comparison nymphs. The identification of mantis homocytes as a large group of pest predators is being investigated for the first time and can be used in the study of its immune features. | ||
