The variations in the activities of the alkaline and acid phosphatases of the silkworm, Bombyx mori, were studied in all stages of the life cycle. From hatching until the spinning stage a steady increase was recorded in the activity of both the enzymes followed with a conspicuous decrease at each moult. During the pupal stage the alkaline phosphatase was almost absent, whereas the acid phosphatase maintained a high and constant value. Increase or decrease of the activity of the enzymes during larval development was reflected in a decrease or increase in the acid-soluble phosphorus content. Acid phosphatase activity slowly increased from laying of the eggs to hatching of the larvae with a concomitant decrease in the acid-soluble phosphorus. Tissue analysis showed a high concentration of the alkaline enzyme in the intestines, but the haemolymph was almost free of both enzymes. Feeding of inorganic phosphate increased the alkaline enzyme in the intestines, whereas glucose had no effect on either of the enzymes in the intestines.
