The bark beetle is a small insect that bores into the bark of a pine tree and creates egg chambers in the cambium, the living tissue of the tree. The larvae feed on the cambium, pupate and emerge as adults to repeat the cycle. Sometimes 3-4 lifecycles occur in one year. Usually the trees can protect themselves against this invasion by pushing out the insects with sap. But during drought or other times of stress, the trees’ defenses are low, and the insects can do enough damage to kill. Traps shown on photo are made of cones bated with beetle pheromones (chemicals the insects use to attract mates). California State Parks considered this approach to be the least disruptive way to save endemic Torrey Pines Trees.
