This paper descributes the changes in Bombyx phagocytic rate during the larval development by measuring the uptake of goose erythrocytes (GRBCs) and the manner whereby hemocytic reactions to foreign colles are initiated. When GRBCs were injected into the hemocoel, they were easily phagocytosed by host hemocytes. On the basis of counting the number of unphagocytoses GRBCs, phagocytic rate was quantitatively measured. By employing such approach, it was shown that the velocity of phagonist of GRBCs by hemocytes increased with the larval age and that the rate of uptake of GRBCs at the 5th instar was highest throughtout the larval age. Wheres, in using GRBCs as foreign cells so as to know the manner of hemocytic reactions, phagocytosis either by a single granular cell or by several was observed. This suggested that the foreignness of the same size as the insect hemocytes was eighter phagocytosed or encapsulated. However, granular cells mostly were involved in this encapsulation. In addition, it was shown that granular cels adhered to GRBCs following random contact, suggestigng that the initial reaction to foreign cells, unlike the second phase by chemotaxis in encapsulation, would occur via random contact.
