Arthropods form the largest and most varied assemblage of organisms on earth. They are notable as agricultural pests, as vectors of disease and as a source of food. Knowledge in the area of arthropod endocrinology has increased greatly in the past decade with the advent of improved techniques for the isolation and study of the hormones themselves, revealing fascinating relationships among the endocrine systems of the various arthropod groups. This collection brings together in a single volume contributions from many of the leading workers in the field, providing in-depth accounts of the current state of knowledge of a wide range of hormone systems. The book presents a unique summary of some of the most significant and exciting advances of the past decade.
