In the present study, five types of haemocytes were identified, viz., prohaemocytes, plasmatocytes, oenocytoids, granulocytes and coagulocytes in the haemolymph of the insect. Total haemocyte count was 4372 cells/mm as an average in the haemolymph. Major abnormalities observed in the haemocytes after the application of nimbicidine was distortion of the shape of blood cells, abnormal staining of the cells, enlargement, denucleation, rupturing of the cells and rupturing of the wall of cytoplasm.
