Textbook in PDF format This textbook is the first to teach insect physiology and biology specifically to students who lack a strong background in biochemistry and molecular biology. Avoiding taxonomic language and supported with high‑quality figures, chapter summaries, end‑of‑chapter review questions, and a suite of PowerPoint slides for use in teaching, it describes the fundamental processes. These include molting and metamorphosis, digestion of food, nerve and muscle function, flight, biological rhythms, circulation and breathing, immunity, how climate and climate change have, and are, affecting insects, and the use of new manipulation of the genome in insect biology and control
