Emerald ash borer has been in Canada for nearly 20 years. Since its discovery it has spread from southwestern Ontario to Canada’s east coast and its prairie provinces. In that time significant progress has been made in the understanding of the insect’s biology, ecology and management, but there is still much work to do. This webinar, presented by Dr. Chris MacQuarrie from the Canadian Forest Service, Natural Resources Canada, will summarize some of the recent research on emerald ash borer in Canada and efforts to manage the damage the insect is still causing.
