Book Description
The papers presented in this book cover the range of forest insect pest management activities in Canada. The first section contains papers on the current status of insect pests by region, including data on insect populations and extent of defoliation caused by the insect. The next section covers pest management technology, including the use of insecticides, insect viruses, fungal pathogens, growth regulators, antifeedants, pheromones, natural predators, and aerial spraying. The third section contains papers on the application of technology and equipment for forest pest control, and includes papers on the impacts of insecticides on the forest environment. The fourth section describes operational control programs by province. The final paper presents future strategies for the management of forest pests. An author index is included.

Book Description
Forest Ecosystem Management. A management approach that aims to maintain healthy and resilient forest ecosystems by focusing on a reduction of differences between natural and managed landscapes to ensure long-term maintenance of ecosystem functions and thereby retain the social and economic benefits they provide to society.That is the definition of forest ecosystem management proposed in this book, which provides a summary of key ecological concepts supporting this approach. The book includes a review of major disturbance regimes that shape the natural dynamics of the boreal forest and gives examples from different Canadian boreal regions. Several projects implementing the forest ecosystem management approach are presented to illustrate the challenges created by current forestry practices and the solutions that this new approach can provide. In short, knowledge and understanding of forest dynamics can serve as a guide for forest management. Planning interventions based on natural dynamics can facilitate reconciliation between forest harvesting needs and the interests of other forest users.

Book Description
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.
