Dual insecticidal effects of Adenanthera Pavonina kunitz-type inhibitor on Plodia Interpunctella is mediated by digestive enzymes inhibition and chitin-binding properties
The Indianmeal moth, Plodia interpunctella, is one of the most damaging pests of stored products. We investigated the insecticidal properties of ApKTI, a Kunitz trypsin inhibitor from Adenanthera pavonina seeds, against P. interpunctella larvae through bioassays with artificial diet. ApKTI-fed larva...
