Chitin and Benzoylphenyl Ureas

The opportunity to explore a developing new technology in a single biological system, chitin, from the molecular basis and with the inter­ relationship of the utilization of benzoylphenyl ureas in effective pest agroecosystem management strategies, represents a new evolution for integration of knowledge in this highly complex area. The degree of great progress and interest in the understanding of the interaction of chitin uItrastructures, biochemistry, and the unique ben­ zoylphenyl ureas attest to the timeliness of this effort. The purpose of the book that follows is to provide up-to-date and well illustrated details of current research knowledge including the latest of research results. The combination of the basic to the applied aspects rarely occurs specifically at the levels presented by the international contributors within. The original contributions composed the symposium Chitin and Ben­ zoylphenyl Urea organized by the co-editors at the International Con­ gress of Entomology in Hamberg, Germany, August 1984. We extend our appreciation to everyone who made the conference an outstanding success and highlight of the Congress, as well as making this book possible. We thank the authors, especially for their excellent international presenta­ tions, discussions, and preparation of the manuscripts. The knowledge evolved from many areas in chitin research, as well as the intricate com­ plexity of successful utilization of specific knowledge involving benzoylp­ henyl ureas in system management strategies for insects will continue to be in the forefront throughout the world's agroecosystems; and hopefully this book will enhance further research and development.
