A native-to-Asia jewel beetle attacking ash trees, now tied to elm disease-linked breeding initiatives
Elm scientists have injected 6,000 young trees with Dutch elm disease spores to test resistance. Survivors will feed a breeding program to boost disease-tolerant elms for forests, riverbanks and yards. Separate injections aim to protect ash trees from emerald ash borer through targeted insecticide treatments along the Appalachian Trail.
