Abstract:
Plant protease inhibitors (PPIs) are plant defensive proteins and often get induced in response to injury or attack by insects or pathogens and are being explored as pest control agents. In the present study plant extracts were screened to identify extracts containing protease inhibitors against the gut proteases of S.litura. Protease inhibition was done using azocasein as substrate at pH 9.0. Out of the 50 plant extracts screened, 13 plant extracts showed greater than 40% inhibition. The highest inhibition (88.60±0.50%) was given by Ardisia solanaceae. Six of the plant extracts contain inhibitors which are proteinaceous in nature and are of potential use in pest control.
