Physiological Systems of Insects is designed to emphasize classical material such as the structure and function of insect organ systems. In addition, the book supplements classical material with insights into insect biology achieved through studies of insect molecular biology, neuroendocrinology, biochemistry, and genetics. Throughout the book there is an effort to lay the experimental foundation upon which studies of insect physiology are based. Students, faculty, and researchers who need a summary of the patterns and processes regulated by physiological systems will want this book.
