In response to the unprecedented spread of bark beetles in the Rocky Mountains and other parts of the western United States, the U.S. Forest Service formed the Western Bark Beetle Research Group (WBBRG) in 2007—a collaboration between scientists from three research stations that pools knowledge and resources to better understand the threat and eventually develop a strategy to combat it.

A forestry mulching machine, also referred to as a forestry mulcher, forest masticator, or brushcutter, uses a rotary drum equipped with steel chipper tools ("teeth") or blades to shred vegetation.

Tiny bark beetles, namely the Ips engraver and southern pine varieties, have been killing millions of trees across Louisiana and Mississippi after a severe drought last year left forests and woods ...
The pinyon ips is a small, brown, cylindrical bark beetle with spines on the distal portion of the abdomen, which is typical for this genus of bark beetles. Pinyon ips has five such spines. The adult’s length ranges between 1 ⁄ 8 inch (3.2 mm) and 1 ⁄ 4 inch (6.4 mm).
The mountain pine beetle has killed large numbers of the lodgepole pine trees in the northern mountains of the US state of Colorado. The more recent outbreak of another bark beetle pest, the spruce beetle, is threatening higher-elevation forests of Engelmann spruce. [1] Chemical prevention is effective but too costly for large-scale use.
Trogossitidae, also known as bark-gnawing beetles, are a small family in the superfamily Cleroidea. Many taxa formerly within this family have been removed (as of 2019) to other families, such as Lophocateridae , Peltidae , Protopeltidae , Rentoniidae , and Thymalidae . [ 1 ]
The bark beetles target oak trees and bore holes through the peridermal tissues, making tunnels within the phloem. The fungal spores are brought into these tunnels by the beetles and begin to colonize the damaged cells inside the tunnels. Symptoms of the developing fungus include wet discoloration seeping from the beetle entry holes as the ...
