This book is about the management of forest pests. It focuses predominantly on insect pests, but many examples relate to fungal pathogens, some of which are vectored by forest insects. The central theme of the book is the development of Integrated Pest Management (IPM), the main impetus for which comes from the need to use environmentally sensitive methods of control appropriate to both semi-natural and plantation forests. Such forests are likely to be managed not only for timber production but also for recreation and to enhance biodiversity. An introductory chapter describes how forests have been transformed by exploitation and management and how altering the composition and distribution of forests can contribute to pest problems. Subsequent chapters focus on the 'techniques' of management and control that contribute to IPM, considering in turn plant health, risk-rating, silviculture, tree resistance, biological control, microbial control and semiochemicals. By focussing on these important elements of management, the aim is to provide a critical analysis of the theory and practice of each one in relation to key aspects of both pest and forest ecology. The final chapter on IPM brings together elements of the previous chapters, discussing them in the context of the economic and environmental impact of pests, the economics of control, and the role of decision support systems. Detailed case studies are provided and future developments in IPM discussed in relation to sustainability, conservation and the potential impact of climate change.

Spruce budworm (Choristoneura fumiferana (Clem.)) outbreaks are a dominant natural disturbance in the forests of Canada and northeastern USA. Widespread, severe defoliation by this native insect results in large-scale mortality and growth reductions of spruce (Picea sp.) and balsam fir (Abies balsamea (L.) Mill.) forests, and largely determines future age–class structure and productivity. The last major spruce budworm outbreak defoliated over 58 million hectares in the 1970s–1980s, and caused 32–43 million m3/year of timber volume losses from 1978 to 1987, in Canada. Management to deal with spruce budworm outbreaks has emphasized forest protection, spraying registered insecticides to prevent defoliation and keep trees alive. Other tactics can include salvage harvesting, altering harvest schedules to remove the most susceptible stands, or reducing future susceptibility by planting or thinning. Chemical insecticides are no longer used, and protection strategies use biological insecticides Bacillus thuringiensis (B.t.) or tebufenozide, a specific insect growth regulator. Over the last five years, a $30 million research project has tested another possible management tactic, termed an ‘early intervention strategy’, aimed at area-wide management of spruce budworm populations. This includes intensive monitoring to detect ‘hot spots’ of rising budworm populations before defoliation occurs, targeted insecticide treatment to prevent spread, and detailed research into target and non-target insect effects. The objective of this Special Issue is to compile the most recent research on protection strategies against spruce budworm. A series of papers will describe results and prospects for the use of an early intervention strategy in spruce budworm and other insect management.

"This report assesses the threat of the mountain pine beetle (Dendroctonus ponderosae Hopkins) to Canada's boreal and eastern pine forests. It is based on available evidence and expert advice provided by researchers and forest managers at two workshops held in Edmonton, Alberta and Victoria, British Columbia during August and September of 2007."--Document.

This publication explains the "why" and "how" of classical biological control in forestry, and addresses the potential risks associated with such programmes. Written by a team of experts, it provides general theory and practical guidelines, featuring 11 case studies of successful implementation efforts worldwide. While insect pests already damage millions of hectares of forest worldwide each year, the extent of such damage is increasing as the impacts of climate change become more evident and as international trade grows, facilitating the pests’ spread. Classical biological control is a well-tried, cost-effective approach to the management of invasive forest pests which involves the importing of "natural enemies" of non-native pests from their countries of origin with the aim of establishing permanent, self-sustaining populations capable of sustainably reducing pest populations below damaging levels.
