This book examines current research on biology, linear developmental model and biological control efficiency. The book draws heavily from insect physiology as the base of knowledge of these fields and is highly advanced in developing a base understanding of virtually every aspect of physiology, such as egg and total body macromolecular profile, enzymes, gut bacterial population, gut protein profile by SDS-PAGE, DNA amplification and genetic similarity in relation to six universal primers and interaction of prey-protein and predator response by ELISA. This book will serve as a bridge for predator rearing specialists and their stakeholders in using various temperatures under storage conditions so as to better manipulate the ways that benefit temperature and environment..
