HEMOCYTES PROFILE OF STINK BUG, CANTHECONA FURCELLUTA Wolff: A SEVERE PEST OF ANTHERAEA MYLITTA DRURY

Abstract

The five types of hemocytes were documented in Stink bug, Canthecona furcelluta Wolff, they are prohaemocytes (PRs), plasmatocytes (PLs), granulocytes (GRs), adipohaemocytes (ADs) and oenocytoids (OEs). PRs are small spherical cells with a centrally located large rounded nucleus filling the entire cytoplasmic area. Mitotic divisions are frequently seen in these cells. PLs are spindle shaped biramous, triramous and possess relatively smaller central nucleus with cytoplasmic prolongations. GRs are spherical with centrally located nucleus. Their cytoplasm is normally crammed with thick granules of diverse sizes. ADs are large, roughly rounded to ovoid in shape with a comparatively small eccentric nucleus. OEs are also large sphere-shaped with a small rounded eccentric nucleus and their cytoplasm is generally thick and uniform. In addition great deal of variations was recorded in the differential hemocyte count (DHC) of nymhal and adult stage.
