Chronobiology is the study of timing mechanisms in biological systems as diverse as plants, animals and some micro-organisms. It includes rhythmic phenomena ranging from short period (ultradian) through daily (circadian) to long period (monthly, annual) cycles of behaviour, physiology and biochemistry. In recent years spectacular advances have been made, particularly in the field of circadian rhythms, and hardly a week passes without important papers appearing in the major scientific journals. The third edition of Insect Clocks, like its predecessors, deals with the properties and functions of clock-like processes in one of the planet's most abundant groups of organisms. The first half of the book is concerned with circadian rhythmicity, the second with annual responses such as over-wintering diapause, seasonal morphs and cold hardiness. Insect Clocks puts modern developments in these fields into a secure framework of the 'classical' literature that has defined the subject. The book is directed at active researchers in the field as well as newcomers and scientists working in many other areas of modern biology. It will also serve as a textbook for advanced and less advanced students and should find its way into university libraries wishing to keep abreast of the times.

Insect Clocks is mainly concerned with the phenomena in which ""environmental time"" has a practical implication for the life of insects for them to perform behavioral or physiological episodes at the ""right time"" and season. This text first discusses the concept of rhythms and clocks, along with the seasonal changes in the environment that affect a particular group of organisms. This book then explains circadian rhythms of insects. Photoperiodism and seasonal cycles of development; photoperiodic response, clock, and counter; and other types of insect clock are also tackled. This text concludes by explaining the anatomical location of photoreceptors and clocks. This publication will be invaluable to those interested in studying insects and their development affected by circles of influences.

This book reviews the physiological mechanisms of diverse insect clocks, including circadian clock, lunar clock, tidal clock, photoperiodism, circannual rhythms and others. It explains the commonality and diversity of insect clocks, focusing on the recent advances in their molecular and neural mechanisms. In the history of chronobiology, insects provided important examples of diverse clocks. The first report of animal photoperiodism was in an aphid, and the time-compensated celestial navigation was first shown in the honeybee. The circadian clock was first localized in the brain of a cockroach. These diverse insect clocks also have some common features which deserve to be reviewed in a single book. The central molecular mechanism of the circadian clock, i.e., the negative feedback loop of clock genes, was proposed in Drosophila melanogaster in the 1990s and later became the subject of the Nobel Prize in Physiology or Medicine in 2017. Thereafter, researches on the molecular and neural mechanisms in diverse insect clocks other than the Drosophila circadian clock also advanced appreciably. Various new methods including RNAi, NGS, and genome editing with CRISPR-Cas9 have become applicable in these researches. This book comprehensively reviews the physiological mechanisms in diverse insect clocks in the last two decades, which have received less attention than the Drosophila circadian clock. The book is intended for researchers, graduate students, and highly motivated undergraduate students in biological sciences, especially in entomology and chronobiology.

Employing the clear, student-friendly style that made previous editions so popular, Insect Physiology and Biochemistry, Third Edition presents an engaging and authoritative guide to the latest findings in the dynamic field of insect physiology. The book supplies a comprehensive picture of the current state of the function, development, and reproduction of insects. Expanded and updated, this third edition continues to challenge conventional entomological wisdom with the latest research and analytical interpretations. It will appeal to undergraduate and graduate students and to working scientists in the biological sciences who need to possess a firm knowledge of the broad principles of insect physiology. See What’s New in the Third Edition: New chapters covering biological rhythms and insect symbioses Adds references from the last several years to bring each chapter up to date Provides new review and self-study questions that aid in distinguishing the most important information and concepts References to websites where illustrative materials have been provided by scientists and contains approximately 2,600 citations Twenty-four pages of color illustrations with new illustrations that emphasize genetic and molecular developments in insect biology Update of the rapidly developing area of postembryonic development of insects, especially the role of the juvenile hormone in insect development While this edition provides new information and significant updates, it also maintains all the features that made previous editions so popular, such as citations that enable you to get to the primary literature easily and understand the thinking, experimentation, and techniques that have enabled the current understanding of the physiology of insects. And clear writing with technical terms explained in the text where they occur. With more than 250 illustrations to help explain physiological concepts and important anatomical details, the book remains the most easily accessible guide to key concepts in the field.
