Abstract

All of insect have proteolytic system helping to consume leaves's protein. The collection substances that can inhibit it couldn't be consumed protein by insect so they couldn't develope and die. This topic research condition to devert and determine caste of activive site Plutelle Maculipennis's proteinase and Pieris rapae' proteinase, from then it becomes to basic for transformation genes that can inhibit proteolitic system of insect.
