Properties of a kunitz-type trypsin inhibitor from delonix regia seeds against digestive proteinases of anagasta kuehniella (Z.) and corcyra cephalonica (S.) (Lepidoptera: Pyralidae)

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. © 2009 Bentham Science Publishers Ltd
