Controlling the Spread Slowing the spread of the beetle, especially its eastward movement, is a key part of ensuring a Mountain Pine Beetle Program. Milder winters and an abundance of mature pine forests due to many years of wildfire suppression has resulted in an unprecedented northern and eastern expansion of mountain pine beetle populations. After the eggs hatch the larvae tunnel away from the egg gallery, forming a feeding chamber which disrupts the nutrient movement of the host tree. The trees respond to attack by increasing their resin output in order to discourage or kill the beetles, but the beetles carry blue stain fungi which, if established, will block the tree resin response.
