Pine bettles are the most common patastie to the Lodgepole pines. lt beetles bore through the thin bark to lay eggs and deposit a fungus carried on their bodies. The larvae live in and feed on the bark during the winter, as does the fungus. The bark damage usually kills the host tree, although sustained temperatures of –25 °C during the early fall or late spring or temperatures of –40 °C during winter can kill the larvae. Infestations usually last 5 to 7 years and happen in 20- to 40-year cycles.
