|
The fine structure of the hemocytes in Wolf spider, Pardosa astrigera, is discribed and compared with that of similar cells in other spider species and insects. Five hemocyte types are identified in the hemolymph: prohemocyte, plasmatocyte, granulocyte, spherulocyte and adipohemocyte. Prohemocytes are small with a relatively undifferentiated cytoplasm. The nucleus is comparatively large and has a perinuclear space. Plasmatocytes and granulocytes are pinocytotic function in the hemolymph of the body. The plasmatocytes have some coated pits on the plasma membrane and well developed Golgi complex, The granulocytes appear sequence of events in the formation of coated vesicle from a coated pit on its plasma membrane. Golgi complex become well expressed and give rise to small secretory vesicles which fuse to large bodies. The spherulocytes are larger in cell size than other hemocytes. Their cytoplasm is filled with spherules. The spherules contain the floccurent materials and the helical structured materials, which are 220nm in length and 80nm in width. The adipohemocytes are oval shaped and have a number of lipid droplets.
