Physiological Systems in Insects, Fourth Edition explores why insects have become the dominant animals on the planet. Sections describe the historical investigations that have led us to our current understanding of insect systems. Integrated within a basic physiological framework are modern molecular approaches that provide a glimpse of the genetic and evolutionary frameworks that testify to the unity of life on earth. This updated edition describes advances that have occurred in our understanding of hormone action, metamorphosis, and reproduction, along with new sections on the role of microbiomes, insecticide action and its metabolism, and a chapter on genetics, genomics and epigenetic systems. The book represents a collaborative effort by two internationally known insect physiologists who have instructed graduate courses in insect physiology. As such, it is the ideal resource for entomologists and those in other fields who may require knowledge of insect systems.

"Physiological Systems in Insects" discusses the roles of molecular biology, neuroendocrinology, biochemistry, and genetics in our understanding of insects. All chapters in the new edition are updated, with major revisions to those covering swiftly evolving areas like endocrine, developmental, behavioral, and nervous systems. The new edition includes the latest details from the literature on hormone receptors, behavioral genetics, insect genomics, neural integration, and much more. Organized according to insect physiological functions, this book is fully updated with the latest and foundational research that has influenced understanding of the patterns and processes of insects and is a valuable addition to the collection of any researcher or student working with insects.

There are about 10 quintillion insects in the world divided into more thanone million known species, and some scientists believe there may be more than 30 million species. As the largest living group on earth, insects can provide us with insight into adaptation, evolution, and survival. The internationally respected third edition of Marc Klowden's standard reference for entomologists and researchers and textbook for insect physiology courses provides the most comprehensive analysis of the systems that make insects important contributors to our environment.
Third edition has been updated with new information in almost every chapter and new figuresIncludes an extensive up-to-date bibliography in each chapter Provides a glossary of common entomological and physiological terms"
