Dr. Richard Hofstetter and Reagan McGuire have "beetle mania." Hofstetter is an Assistant Professor at Northern Arizona University's School of Forestry. McGuire is a Research Assistant. The two have been studying the habits of the bark beetle, a tiny bug that has killed millions of pine trees all over the West, including Arizona. Attempts to control it have been largely unsuccessful. However, Hofstetter and McGuire have been using a new approach to affect bark beetle behavior: They record the calls of the beetles, manipulate them, and play them back to them. The bugs react immediately.
Mark Duggan talks with Hofstetter and McGuire about setting up a habitat that was basically a sound stage. McGuire talks about the reaction of the beetles upon hearing their own heavily manipulated sounds.
Is this is a new way to control one of the West's most invasive species?
