Keeping our plants healthy means engaging living biological agents that might not occur naturally on our landscapes. Award winning entomologist, Dr. Richard McDonald focuses on how to incorporate beneficial biological introductions and match them with preventative measures as our first line of defense against insect and disease pressure. In part 5, Dr. McBug describes how the wooly adelgid problem with eastern hemlocks started. He describes how he’s helped mitigate the infestation as much as possible in our western North Carolina mountain forest ecosystem through extensive efforts to bring in their natural predator from the forests near Seattle, WA. Learn how to utilize ultraviolet light to spot the waste of adelgids and other pests and gain a whole new perspective on insect populations and keeping them in balance.
