approximatus does not actively kill trees, but rather infests down trees or weakened trees already experiencing attacks initiated by primary bark beetle species (Wood 1982; Cibrian Tovar et al.

As warming continues, the predictions are we will have more devastating outbreaks, not only of mountain pine beetle, but of many species of bark beetles.

To reproduce, bark beetles have to gain entry to the tree.
