Insects multiply. Destruction reigns. There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they always work. They have never been known entirely to fail. Likewise they have never been known to prevent the next outbreak. For the cycle of abundance and scarcity has a rhythm of its own, and the Cures are applied just when the plague of insects is going to abate through its own loss of momentum. -Abridged, with insects in place of voles, from C. Elton, 1924, Voles, Mice and Lemmings, with permission of Oxford University Press This book is an enquiry into the "natural rhythms" of insect abundance in forested ecosystems and into the forces that give rise to these rhythms. Forests form unique environ ments for such studies because one can find them growing under relatively natural (pri meval) conditions as well as under the domination of human actions. Also, the slow growth and turnover rates of forested ecosystems enable us to investigate insect popula tion dynamics in a plant environment that remains relatively constant or changes only slowly, this in contrast to agricultural systems, where change is often drastic and frequent.

This new approach to insect modeling discusses population dynamics' regularities, control theory, theory of transitions, and describes methods of population dynamics and outbreaks modeling for forest phyllophagous insects and their effects on global climate change. Research in insect population dynamics is important for more reasons than just protecting forest communities. Insect populations are among the main ecological units included in the analysis of stability of ecological systems. Moreover, it is convenient to test new methods of analyzing population and community stability on the insect-related data, as by now ecologists and entomologists have accumulated large amounts of such data. In this book, the authors analyze population dynamics of quite a narrow group of insects – forest defoliators. It is hoped that the methods proposed herein for the analysis of population dynamics of these species may be useful and effective for analyzing population dynamics of other animal species and their effects and role in global warming. What can insects tell us about our environment and our ever-changing climate? It is through studies like this one that these important answers can be obtained, along with data on the insects and their behaviors themselves. The authors present new theories on modeling and data accumulation, using cutting-edge processes never before published for such a wide audience. This volume presents the state-of-the-art in the science, and it is an essential piece of any entomologist's and forest engineer's library.

This book covers the full breadth of forest entomology. It combines the work of forest entomologists working on the impact and management of forest pests with those involved in diversity assessment and conservation of insects in forests. Forests and Insects demonstrates that both these disciplines demand an understanding of population and community biology. The book covers such topics as colonization of trees by insects, population dynamics of forest insects, insect natural enemies, the effects of climate change and pollution on forest pests, spatial variation in the abundance of insects,the mineralization of carbon by termites, the impact of herbivorous insects, and the conservation of forest insect diversity, including the effects of forest fragmentation and deforestation. This Royal Entomological Society Symposium volume will be of great interest to all agricultural and forest entomologists, population and community biologists, pest management specialists and anyone concerned with the conservation of forest biodiversity.

This book is intended as a general text for undergraduates studying the manage ment of forest insect pests. It is divided into four parts: insects, ecology, manage ment, and practice. Part I, Insects, contains two chapters. The first is intended to provide an overview of the general attributes of insects. Recognizing that it is impossible to adequately treat such a diverse and complex group of organisms in such a short space, I have attempted to highlight those insectan characteristics that make them difficult animals to combat. I have also tried to expose the insects' weak points, those attributes that make them vulnerable to manipulation by human actions. Even so, this first chapter will seem inadequate and sketchy to many of my colleagues. Ideally, this book should be used in conjunction with a laboratory manual covering insect anatomy, physiology, biology, behavior, and classifica tion in much greater depth-in fact, this is how I organize my forest entomology course. It is hoped that this first chapter will provide nonentomologists with a general feel for the insects and with a broad understanding of their strengths and weaknesses, while Chapter 2 will provide a brief overview of the diverse insect fauna that attacks the various parts of forest trees and their products.

S2The purpose of the Forest Insect Population Dynamics Workshop was to permit some probing in depth of forest insect populations systems and to provide an opportunity for the exchange of ideas and information in this subject. Organized and developed primarily for Forest Service personnel interested or involve in quantitative population studies of forest insects, the Workshop was augmented by outside scientists expecially knowledgeable and experienced in pertinent facets of population dynamics The program was oriented to the researcher, with emphasis on approaches and methods of analysis, but with due consideration of output and applications.S3.

Excerpt from Forest Insect Population Dynamics: Proceedings of the Forest Insect Population Dynamics Workshop, West Haven, Connecticut, 23-27 January 1967 The format was simple. One day was given to each of four major subject areas. The primary presentations, which comprise the text of this publication (with the exceptions noted below), were given in the mornings, followed by questions, answers, and discussion of the subject. The presentation of Dr. Wyatt W. Anderson (then with Yale University) on the fundamentals of population genetics and its interplay with population ecology is not included in this Proceedings because of the basic nature of the informa tion and its availability in standard texts. The paper by Dr. Charles L. Remington (yale University) on the genetic consequences of insect population displacement or transport is omitted also because it has been published in Volume 15 (1968) of the Annual Review of Entomology. Unfortunately the taped recordings of the open discussions could not be transcribed adequately, and so this vital portion of the Workshop cannot be included.
