Canada is a world leader in biological control research. Reporting the status of biocontrol agents released in Canada over the last decade, this book presents case studies by target pest that evaluate the impact of biocontrol and recommend future priorities. In addition to a new chapter on future targets and an appendix listing established agents, this edition contains information of interest to a global audience, and chapters that address effects of invasive species and climate change.
