Current Events in the Plant Pest Realm


Mark has been studying insects that feed on trees for over 30 years, the last 15 of which he has focused on invasive non-native species that are changing the face of North America’s forested landscape. He started his career in forest entomology studying spruce beetles in Alaska, moved to Berkeley to focus on biological control of forest pests, and has been at Cornell since 1989. Mark currently works with professional land managers, state and federal agencies, local government officials, and concerned citizens to help them understand the issues surrounding and strategies for minimizing the impact of non-native invasive insects such as the emerald ash borer and hemlock woolly adelgid. Mark’s current research focus is on biological control of hemlock woolly adelgid.
