An Introduction to the Book.

Chitin is a linear biopolymer composed of ß-1,4-linked N-acetylglucosamine (GlcNAc), and an essential component in exoskeleton of insects and crustaceans, the egg shells of parasitic nematodes, and the fungal cell wall. Since the chitin-containing organisms often threaten human health, food safety, and agricultural production, it has been highly desirable to control the hazardous chitin-containing organisms. This book will provide researchers and students with information on the recent research progress about the biology of chitin-containing organisms and their cross-talk with other organisms. This book also contains essential knowledge of drug design for controlling chitin-containing organisms. The authors deeply hope this book brings more attention to the fascinating yet unexploited world of chitin. We would like to thank all contributors for their expertise and generous support.
