Mountain Pine Beetles
Mountain pine beetles (MPB) are the most important insect pest of Colorado’s pine forests. MPB often kill large numbers of trees annually during outbreaks. Trees that are not growing vigorously due to old age, crowding, poor growing conditions, drought, fire or mechanical damage, root disease and other causes are most likely to be attacked.
Trees attacked by mountain pine beetles are generally killed. Attacks may occur on individual pines or involve variable-sized groups of hosts. Normally, mountain pine beetles attack trees that are under stress due to competition with other trees, are weakened by pathogens, or are otherwise debilitated. Periodically on some hosts, large-scale outbreaks can occur and infestations can extend into stands of healthy trees.
