Abstract： The study of structure and synthesis of vitellin, uptake process by ovary and the mechanism of hormone regulation is one of concentrated studies in insect physiology. In recent years, with the development of the molecular cloning technology, genetic engineering and bioinformatics, the study of vitellin gene will provide a new method to biological control of pests. In this article, we reviewed the researches on insect vitellin and its hormonal regulation, which is helpful to understand mechanism of pest resurgence and to control the pests using natural enemy.
