Abstract

|
Insect hemocytes during metamorphosis were studies by histchemical and autoradiographic methods is Pieris rapae (Lepidoptera). The hemocytes were classified into six types, prohemocytes, plasmatocytes, podocytes, granular hemocytes, spherule cells and oenocytoids on the basis of the transitions in shapes and inclnsions of cytoplasms. Proteins, nucleic acids, polysaccharides and lipids in the hemocytes were detected histochemically from larval to pupal stages to learn the rise and fall of them during growth and metamorphosis. Most of the granules consisted of glycogen, neutral mucopolysaccharides and mucoprotein in addition to some granules of neutral fats and phospholipids were found in the granular hemocytes and spherule cells. Mitotic figures and DNA synthetic activities were observed in every type of hemocytes from 2nd to 5th instars, suggesting the all types of hemocytes originated from the prohemocytes. The cytoplasmic filaments of plasmatocytes and pdocytes extended very long in prepupa and pupa and the vermiform cells were the transformed plasmatocytes due to their further differentiation.
