Across nine comprehensive chapters, Cymborowski blends extensive original research with critical engagement with global literature to explore the role of hormones in the life cycle of insects. The book opens with a conceptual and historical introduction to insect endocrinology, including key problems such as hormonal feedback, circadian rhythms, and molecular regulation of metamorphosis. A detailed anatomical survey follows, mapping the structure and function of the neuroendocrine system - from neurosecretory cells and corpora allata to the prothoracic glands. Chapter 3 outlines a broad range of technical approaches - including endocrine gland ablation, parabiosis, in vitro culture, autoradiography, and multiple bioassay protocols - that together provide a foundation for experimental endocrinology in invertebrate systems. Chapters 4-8 present richly detailed discussions of how specific hormones, including PTTH, juvenile hormone, ecdysone, bursicon, and others, orchestrate developmental transitions, reproductive processes, diapause, and behavioural changes. These analyses synthesise hormonal interactions within ecological and physiological contexts, highlighting the interplay between endocrine signalling and environmental factors like temperature, photoperiod, and nutrition. The final chapter turns to applied entomology, addressing the use of insect hormones and analogues as a new generation of insecticides. Cymborowski offers a prescient discussion of juvenoids, ecdysoids, and hormone inhibitors, evaluating their mechanisms of action. With its blend of classical theory, methodological rigour, and applied relevance, Insect Endocrinology continues to be a valuable resource for anyone working in invertebrate physiology, developmental biology, or integrated pest management. -- Contents [Summary & References in each chapter]: 1.

Hardcover. Dust Jacket Included. pp.xii, 234 with b/w. plates & figs. 8vo. Hardback. Author's dedication to ffep. Owner's stamp to ffep and text block edges. Fine hardback in thor. vg. to nr. fine dw. Presents a wide range of information on the insect endocrine system. Particular attention is given to the mechanism of action of insect hormones during growth and metamorphosis, with special reference to the functioning of the organism as a whole. The role of insect hormones in reproduction, diapause and the regulation of metabolism and behaviour is discussed. The prospects for insect hormones as insecticides are also considered.
