NPS fights fire with fire, actually insect with insects

SEVIERVILLE, Tenn. (WVLT) -- Great Smoky Mountains National Park resource managers are fighting fire with fire - rather they're fighting insect with insect. The park service plans to release two new predatory beetle species to help control the spread of the Hemlock Woolly Adelgid (HWA).

Since 2002, they've been releasing predatory beetles, which feed only on adelgids, and hope that these two new beetles will help them keep the species under control.

While the HWA hailed from Washington, these two new predators are coming all the way from Osaka, Japan.

Eventually, park managers expect the beetles will reach a natural balance with the HWA populations, as they have in Washington, British Columbia, and Japan.
