Justin Whitehill is hopeful that “we will eventually be able to produce EAB-resistant ash trees by borrowing from other ash trees that have natural resistance. Applying modern genomic technologies to conventional tree-breeding methods has the potential to preserve not only a single species, but a whole genus that is being impacted worldwide.”
Paul Merten has spent nearly a decade chasing down a killer in the Southern Appalachians, armed with no more than a pocket knife and measuring tape.But recently the entomologist with the U.S. Forest Service in Asheville, N.C., has been homing in on the tiny, yet lethal pest with what he hopes is a secret weapon — parasitoids, also known as wasps.Merten and Haywood County Community College forestry student Caroline McGough were deep in the woods on the Appalachian Trail slicing across the North Carolina-Tennessee border last week, unleashing parasitoids in a science fiction-like attack on the emerald ash borer.
Researchers here are hatching a plan to stop the woolly adelgid. A 1-acre plot of forest is the site of a budding insectary, a farm in the trees of the predator beetle Laricobius nigrinus that has been shown in some cases to kill the adelgid.
