Haemocyte types and count in Bradinopyga geminata (Rambur) (Anisoptera: Odanata)

Author(s): Raveen R, Nalini M
Abstract: Seven haemocyte types were identified in the haemolymph of adult Bradinopyga geminata (Rambur) (Anisoptera: Odanata) viz., Prohaemocytes, plasmatocytes, granulocytes, oenocytoids, adipohaemocytes, spherulocytes and vermicytes. Prohaemocytes, plasmatocytes and granulocytes were the most numerous circulating haemocytes in the haemolymph of Bradinopyga geminata. Prohaemocytes were the smallest cell type, spherical in shape with a centrally located large nucleus. The plasmatocytes were polymorphic with or without cytoplasmic extensions. The granulocytes were spherical or oval in shape with characteristic basophilic granules in the cytoplasm. Oenocytoids were the largest of all the cell types with a large nucleus and a homogenous cytoplasm. Adipohaemocytes were polymorphic, varied from small to large cells mostly irregular in shape with prominent lipid-like inclusions. The spherulocytes were characterized by the presence of highly basophilic or acidophilic spherules. Vermicytes were fusiform with a centrally located nucleus. The total and differential haemocyte counts were also done.
