Spruce bark beetles don’t just tolerate their host tree’s chemical defenses—they actively reshape them into stronger antifungal protections. These stolen defenses help shield the beetles from ...

For the first time, a research team has mapped out exactly what happens when spruce bark beetles use their sense of smell to find trees and partners to reproduce with. The hope is that the results ...

Adult spruce bark beetles in their galleries in the bark of a Norway spruce tree. The beetle in the middle is infected with the fungus Beauveria bassiana. Spruce bark is rich in phenolic compounds ...

Large infestations of the destructive bark beetle have become more frequent — and there's really no way to save trees once a large outbreak occurs. Diana Six, a professor at the University of Montana, ...

On the northwest corner of Manito Park, dozens of ponderosa pines appear to stand strong. Joggers and dog walkers weave through the towering trunks on their morning routes, and gray squirrels run ...

Spruce bark is rich in phenolic compounds that protect trees from pathogenic fungi. A research team at the Max Planck Institute for Chemical Ecology in Jena investigated how these plant defenses ...
