| Research Abstract |
To elucidate biochemical mechanisms of oosorption in a stink bug, Plautia stali, genes encoding proteases responsible for protein degradation in oosorption were cloned, and a method to detect protease activity was established. Chemical analysis of the product of corpora allata and asymmertic synhtesis methods revealed a new structure of juvenile hormone in this insect, which played an important role in egg production and oosorption.
