A considerable amount of research has been carried out in the past decade in developing knowledge for rearing mass numbers of arthropods for field and laboratory studies. This research has led to a better understanding of the ecology, behavior and reproduction of various arthropod species and has resulted in significant contributions to agricultural and medical entomology. There are 57 authors who have contributed to 39 specific chapters in this book. Some chapters deal with a single species that is intended to serve as an example of a group with similar requirements. Other chapters discuss rearing methods for an entire group that share common needs. A number of chapters reveal the problems that are encountered in mass production and the methods of over-coming these problems and include nutrition, optimum physical factors for various life stages, methods of securing maximum reproduction, behavior in the laboratory, rearing equipment, and so forth.
