Abstract

Hemocytes squashed from prothoracic legs of 50 male and 50 female corn weevils, Sitophilus zeamais (Motsch.) were air dried and stained with wright's stain. Based on Gupta's (1979) identification key, two types of hemocytes predominantly occured in both of S. zeamais. prohemocytes and granulocytes. The total hemocytes counts in females were significantly higher (at =0.01 and = 0.05) in number (80.20 hemocytes/slide) than those in males (57.74 hemocytes/slide). Prohemocyte diameters were significantly larger (at a=0.01 and 0.05) in males (ave.=12.53 u) than females (ave.=8.61 u) However, the diameter of granulocytes in both sexes were insignificantly different.
