An Ultrastructural Study on Larval Hemocytes of Acrida cinerea Thunberg

The ultrastructures of hemocytes of Acrida cinerea Thunberg were studied and 4 types of hemocytes were noticed; prohemocytes, plasmatocytes, granular cells and adipohemocytes. Prohemocytes were the smallest of all cell types with poor cytoplasmic organelles, such as endoplasmic reticulum, Golgi complexes, vacuoles and Iysosomes. Plasmatocytes were round or oval with many cytoplasmic processes, vacuoles, endoplasmic reticulum and even myelinated bodies. Granular cells were spindle-shaped or oval. In both cases, they are characterized by various granules. Adipohemocytes were very rich in lipid droplets and microtublles.
