Beetle and Fungus Have 'Gone Rogue,' Threaten Walnut Trees
The walnut twig beetle was once nothing but a nuisance for black walnut trees across the western United States.

This has allowed the once-pests to "go rogue," now inflicting near-irreversible and sometimes fatal damage to these trees and trees like them.
