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.

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.

Larry Pedigo and Marlin Rice have produced the top pest management textbook on the market for decades. New co-author Rayda Krell has helped bring the book into the twenty-first century. The successful core concepts of the book—understanding pests in their environment and using an ecological approach to combat them—remain as robust as ever. Features that instructors have come to rely on have been retained, including insect diagnostic boxes with detailed information on important species and species groups and an appendix with keys to major insect orders. New material on genetically modified plant species and regional pest technologies complement concepts in basic and applied entomology. Taxonomies and systematics of insects have been updated throughout the book.

The dominance of insects in the world fauna has made them the humanity's greatest rival for the world's food resources, both directly by eating the plants cultivated for food and indirectly as vectors of pathogens attacking these plants. Agricultural scientists and especially entomologists have strived hard to develop a diversity of cultural, mechanical, biological and chemical weapons during the last more than two centuries to gain dominance over insects. However, there is evidence that insect pest problems have escalated with an increasing cropping intensity and with the use of agrochemicals inherent in modern agriculture. Consequently, Indian plant protection scientists have intensified research on the development of pest management tactics and effective pest management systems have been designed for all the important crops in the country. This book, consisting of 29 chapters, draws together the diverse literature on the subject of insect pest management in agriculture and contains contributions written by scientists having extensive experience with insect pest problems in Indian agriculture. The first half of the book is devoted to the principles and components of pest management including factors affecting pest populations, construction of life tables, coevolution of insects and plants, pest forecasting, pesticides, IGRs, botanicals, entomopathogenic nematodes and molecular approaches, etc. The different tactics for the management of major insect pests of principal agricultural crops of India, viz. rice, maize, wheat, forage crops, cotton, sugarcane, vegetables, fruits, oilseeds, pulse crops, jute, mesta and tobacco have been discussed in the second half of the book. The book contains a wealth of information on all aspects of insect pest management in agriculture under Indian conditions and would prove indispensable for students, teachers and researchers in agricultural entomology in India and other Asian countries.
