Pinyon Pitch Mass Borer

The Pinyon Pitch Mass Borer (Resinosis (Terpene) Compositionum) is a type of bark beetle that attacks Pinyon Pine trees in the western United States. The larvae of this insect feed on the sap and tissues within the tree, creating a sticky, sap-like substance known as pitch. This substance can build up and obstruct the tree's ability to transport water and nutrients, leading to wilting, yellowing and eventual death of the tree. The adult beetles typically emerge from the trees in early summer, and lay eggs in crevices and cracks in the bark. Management of Pinyon Pitch Mass Borers can include cultural practices such as proper watering, pruning, and fertilization to keep trees healthy and better able to resist attack. Pesticides can also be used to control the beetles, though they may not be effective if applied after the larvae have already entered the tree. In addition, removing and destroying infested trees can help to reduce the overall population of the beetles. If you suspect that your Pinyon Pine trees are being attacked by Pinyon Pitch Mass Borers, it is important to seek the assistance of a professional tree care specialist. They can help you identify the problem and recommend the best course of action to help protect and preserve your trees.
