Dendroctonus terebrans - Black Turpentine Beetle



This beetle is often found in Pines. It creates these paths (galleries) behind the bark and fatally damages the tree in most cases.

Most insects don't attack healthy trees. Other things have stressed the tree that makes it susceptible to insect problems.
Some of the most common stressed of trees are:
  • Over watering and poor drainage
  • Soil compaction
  • Herbicide damage
  • Root or trunk damage
  • Improper pruning and maintenance

This year, many insects are slow to start their life cycle due to very cool temperatures.  Are you spraying or treating for certain insects. If so, timing is critical and procedure is crucial.
