This book is an attempt at taking of what is understood at present about the population dvnamics of insect and the ecological aspects of pest control. It is small, and sets out to outline the development of ecological principles and their application. Much additional reading willbe necessary for those who wish to obtain a detailed knowledge of insect ecology. The decision to write the book was made a few years ago the couse of an exercise undertaken by therr of us to clarify and defineour ideas. Except for R.F. Morris of the department of forestry, Canada, we are (or have been) menbers of the staff of the division of entomology, C.S.I.R.O., Australia, and were appoinnted by A.J. Nilcholson when he has chief of that division.

Insects are by far the largest group of animals on Earth, with over a million described species, and they occupy a wide range of ecological niches - they may be herbivores, predators, parasites or decomposers. Some are of particular economic importance as pests of agriculture and forestry, as vectors of animal and human disease, or as species of interest to wildlife conservation. Thus an understanding of the processes determining their numbers is of considerable practical value. Entomologists have played a leading role in developing a theoretical basis to Population Ecology, but we still do not have adequate experimental and observational proof for many of the theoretical ideas that have been proposed. As a result, the subject has been beset with arguments for more than 50 years. This volume attempts to reconcile some of these controversies, while also reviewing the current state of our knowledge. The editors have drawn together an international list of contributors whose views reflect a range of opinions on how natural populations are stabilised. They have succeeded in producing a book that both covers the main alternative views in population theory and contains some of the best recent field studies of insect populations. This Royal Entomological Society Symposium volume will be of great interest to all entomologists and ecologists, particularly those who wish to know more about Population Dynamics.

Insect Ecology is the world's foremost reference to the never-ending and crucial interactions of the richest taxon of organisms on this earth, with perhaps some 8 million extant species. Now in its Third Edition and twentieth year of publication, Insect Ecology has endured as an unparalleled classic. Taking the reader from an explanation of the science to its significance as a discipline, Insect Ecology is a meticulous, systematic examination of the underlying dynamics of plant-insect interactions, predation, parasites and hosts, and mutualistic relationships, including pollination ecology, that are central to understanding the insects' role in nature. Viewing the largely invisible drama of natural protagonists and antagonists, hidden in the lush foliage of a tropical rain forest or temperate woody vegetation, Peter Price details the unique traits, behaviors, and functions of insects, while placing them in the broader contexts of their places in food webs, ecosystem function, population dynamics, and community interactions. The author also describes the various levels of insect interaction, from trophic relationships (Part II), populations (Part III), and communities (Part IV), while unfolding the infinite variety of insect species and their visible legacy in the fossil record. Full of fascinating details ("Ants are everywhere, but only occasionally noticed. They run much of the terrestrial world as the premier soil turners." "[Insect] galls provide tanning acids and the basis for inks."), Insect Ecology offers detail and breadth, while providing timely discussion on the conservation of biodiversity, the existence and study of vacant ecological niches, latitudinal gradients in species richness, and evolutionary perspectives on population dynamics. The book also examines the development of theory in insect ecology and how it is advanced. Novel features in the Third Edition include four new chapters, covering the importance of insect ecology, the development of theory in the science, hypotheses on plant and herbivore interactions, and a synthesis chapter on population dynamics. Subheadings within chapters provide easier subject access, and many new figures contribute to the book's aesthetic appeal. Clearly organized and with a bibliography of 2,000 references to up-to-date and classic literature, the Third Edition of Insect Ecology is a practical, well-formatted resource. Also copiously illustrated with over 350 figures, many new to this edition, Insect Ecology is a lush graphic tour of the minute, often startling universe of insects in their native habitat. With a history in geologic time much older than the terrestrial vertebrates, insects speak to us-the scarab beetle encased in amber, or New Zealand's endangered large Wellington speargrass weevil-of a resilience and ingenuity oddly reflective of our own. Insect Ecology has let generations of agriculturalists, ecologists, entomologists, environmental scientists, foresters, professionals, and students understand the insects' world, and ours. With unerring detail and breadth, Insect Ecology has described for generations of professionals the interactions and dynamics of the world's richest group of species-the insects-whose wildly various 8 million forms have been the source of endless fascination and study. From caterpillars to the goliath beetle, from the adult copper butterfly to the agromyzid fly, the insect universe is at once ordinary and exotic, capturing, in microcosm, nature's complexity and beauty.

The third edition of Insect Ecology: An Ecosystem Approach provides a modern perspective of insect ecology that integrates two approaches traditionally used to study insect ecology: evolutionary and ecosystem. This integration substantially broadens the scope of insect ecology and contributes to prediction and resolution of the effects of current environmental changes, as these affect and are affected by insects. The third edition includes an updated and expanded synthesis of feedback and interactions between insects and their environment. This updated material and a new chapter on applications of insect ecology to social and environmental issues effectively demonstrates how evolutionary and ecosystem approaches complement each other, with the intent of stimulating further integration of these approaches in experiments that address insect roles in ecosystems. Effective management of ecosystem resources depends on evaluation of the complex, often complementary, effects of insects on ecosystem conditions, as well as insect responses to changing conditions. Timely revision of a key reference on insect ecology Full coverage of ecosystem structure and function balanced with essential background on evolutionary aspects New chapter on applications to issues such as pest management, ecosystem restoration, invasive species and environmental changes Case studies highlight practical and theoretical applications for topics covered in each chapter

From its inception, the U.S. Department of the Interior has been charged with a conflicting mission. One set of statutes demands that the department must develop America's lands, that it get our trees, water, oil, and minerals out into the marketplace. Yet an opposing set of laws orders us to conserve these same resources, to preserve them for the long term and to consider the noncommodity values of our public landscape. That dichotomy, between rapid exploitation and long-term protection, demands what I see as the most significant policy departure of my tenure in office: the use of science-interdisciplinary science-as the primary basis for land management decisions. For more than a century, that has not been the case. Instead, we have managed this dichotomy by compartmentalizing the American landscape. Congress and my predecessors handled resource conflicts by drawing enclosures: "We'll create a national park here," they said, "and we'll put a wildlife refuge over there." Simple enough, as far as protection goes. And outside those protected areas, the message was equally simplistic: "Y'all come and get it. Have at it." The nature and the pace of the resource extraction was not at issue; if you could find it, it was yours.

An understanding of the dynamics of populations is critically important to ecologists, evolutionary biologists, wildlife managers, foresters, and many other biologists. This edited treatise brings together the latest research on how populations fluctuate in size, the factors that drive these changes, and the theories explaining how populations are regulated. The book also includes specific chapters dealing with insects of economic importance.
