Bark beetles rocked by sound

A phenomenon being dubbed Beetlemania is playing out in northern Arizona.

As can be expected, it involves rock music. But instead of screaming fans, there are cheering scientists who have found a way to drive bark beetles crazy with sound.

In a Northern Arizona University School of Forestry lab, researchers are listening to the sound of western forests under attack: the scratching, scraping, crunching of the Ips bark beetle and its cousins chewing the life out of ponderosa, pinyon and lodgepole pines.
