Abstract

Lysozyme activity in normal hemolymph was determined during the larval-pupal development of the silkworm, Bombyx mori. The lysozyme level in young larvae was approx. 40 μg Bombyx lysozyme protein per ml of hemolymph, then increased to 100 μg/ml in mature larvae and decreased again to 60 μg/ml upon pupation. Immunization of larvae or pupae by the injection of soluble peptidoglycan (SPG) induced an increase in lysozyme activity within 24 hr to a level of approx. 440 μg/ml, which was almost constant independent of the developmental stages of the insect. Induction of cecropin by SPG was parallel to the induction of lysozyme.
