Pathogens can drive the evolution of social behavior in insects. Ants and honeybees share nests of hundreds or thousands of individuals in a very small space. Hence the risk is high that infectious ...

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, ...

Researchers have successfully mapped the entire genome of the Eurasian spruce bark beetle. The breakthrough paves the way for new research into bark beetles and better prospects for effective pest ...

For the first time, a research team led by Lund University in Sweden has mapped out exactly what happens when spruce bark beetles use their sense of smell to find trees and partners to reproduce with.

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 ...

American Elm (Ulmus americana) *Most severe issue due to Dutch Elm Disease. Elm (Ulmus spp.) Most significantly, these two species are vectors of the pathogen of Dutch Elm Disease, Ophiostoma ...

While bark beetles have been slowly infesting trees in Aspen, winter won’t offer any respite. Aspen is currently home to the Douglas-fir beetle, the spruce beetle, the mountain pine beetle, Ips ...

Ants and honeybees share nests of hundreds or thousands of individuals in a very small space. Hence the risk is high that infectious diseases may spread rapidly. In order to reduce this risk, the ...

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 ...

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 ...
