The Western Pine Beetle is a small insect native to North America, primarily affecting pine trees. It is known for its role in forest ecosystems, where it can cause significant tree mortality, especially during outbreaks. The beetle typically targets stressed or weakened trees, laying eggs beneath the bark, where larvae feed on the tree's tissues. These beetles are often associated with environmental factors such as drought and high temperatures, which can weaken trees and make them more susceptible to infestation. Management strategies include monitoring tree health and implementing controlled logging to reduce beetle populations and protect forest health.
