Abstract:
Six types of haemocytes are present in the adults of Dysdercus cingulatus. These are: prohaemocytes, plasmatocytes, granular cells, spherule cells, oenocytoids and cystocytes. The same types are pre- sent in the different nymphal instars except for oenocytoids which are absent in the first three in- stars. Plasmatocytes and spherule cells are seen the most abundant cells except in the newly emerged adults where prohaemocytes dominate. But in the mated females plasmatocytes are again dominant and nearly three times the number of prohaemocytes. Spherule cells form about one fifth of the total haemocyte count in the 5th instar and adults. In the 3rd and 4th instars they equal plasmatocytes in numbers. They have phagocytic threads. Oenocytoids are the least common haemocytes throughout the life of this bug.
