The Pine Beetle is the most destructive forest pest in North America. The Canadian Forest Service describes the current pine beetle epidemic as the largest insect infestation in North American history. Verbenone is a pheromone treatment that tricks the beetles into thinking that the tree is already infested and that they need to look elsewhere for a suitable host tree.
These Ponderosas are at slightly lower risk than most lodge pole forests because ponderosas generally grow further apart. When trees are spaced more generously, the beetles have a harder time flying from one tree to another. Thinning is a good practice to naturally protect the trees.
Verbenone is an anti-aggregation hormone that repels pine beetles from target trees.

See "Preventative Spraying Techniques to Control Mountain Pine Beetles" Studies have shown that during epidemic conditions, the pressure from beetle populations who must go SOMEWHERE (even if conditions are not optimum for them) may reduce the effectiveness of all treatments. Given the "find a tree of any size or perish" imperative that emerging pine beetles face, they may habituate to both chemicals and pheromones. However, we still have a few years to work on the problem in areas that are not yet overrun. That time may give just the breather necessary to let nature begin to draw back the danger or for other management techniques to take hold.
