Abstract

DrTI was effective against trypsin-like enzymes from A. kuehniella and C. cephalonica, however an artificial diet was insufficient to affect the survival and body weight of either insect. The inhibitor stimulated chymotrypsin-like enzymes and probably induced the synthesis of enzymes insensitive to TLCK in neonate larvae.
