Book Description
Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.

Book Description
INSECTS PROVIDE an ideal medium in which to study all the problems of physiology. But if this medium is to be used to the best advantage, the principles and peculiarities of the insect's organization must be first appreciated. It is the purpose of this book to set forth these principles so far as they are understood at the present day. There exist already many excellent text-books of general ento mology; notably those of Imms, Weber, and Snodgrass, to mention only the more recent. But these authors have necessarily been preoccupied chiefly with describing the diversity of form among insects; discussions on function being correspondingly condensed. In the present work the emphasis is reversed. Struc ture is described only to an extent sufficient to make the physiological argument intelligible. Every anatomical peculiarity, every ecological specialization, has indeed its physiological counterpart. In that sense, anatomy, physiology and ecology are not separable. But regarded from the standpoint from which the present work is written, the endless modifications that are met with among insects are but illustrations of the general principles of their physiology, which it is the aim of this book to set forth. Completeness in such a work is not possible, or desirable; but an endeavour has been made to illustrate each physiological characteristic by a few concrete examples, and to include sufficient references to guide the student to the more important sources. The physiology of insects is to some the handmaid of Economic Entomology.

Book Description
Insect Photoperiodism reviews the many aspects of photoperiodism, particularly in insects, emphasizing the concepts that serve to place the subject in a meaningful relationship to the whole of modern biology. Photoperiodism is the study of the adaptive mechanisms by which living systems exploit this source of temporal information. Organized into 12 chapters, this book begins by discussing the relationships between an endogenous behavioral rhythm and the exogenous photoperiod. Aside from behavioral activities, it also shows that some observable developmental events tend to occur at species-typical times of the day and to be photoperiodically regulated. Notably, photoperiod may exert either or both of two regulatory effects on insect development: growth rate effects or polymorphism. Furthermore, the characteristics of some of the principal physiological rhythms that have been studied; role of photoperiod in the control of diapauses; and the circadian functions and theoretical nature of biological clock are explored in this book.
