Dendroctonus ponderosae
Mountain Pine Beetle
Dendroctonus ponderosae, commonly known as the mountain pine beetle, is a bark beetle native to western North America. It is a significant forest disturbance agent that attacks and kills pine trees, particularly during outbreak conditions. The beetle has a hard black exoskeleton and measures approximately 5 mm. Population success is heavily influenced by temperature, which drives phenology and adult emergence synchrony required for mass attacks on host trees. The species has been responsible for extensive tree mortality across millions of acres in the western United States and Canada.
