CONTROL BLACK TURPENTINE BEETLE (BTB)

CONTROL BLACK TURPENTINE BEETLE (BTB)(Dendroctonus terebrans). This beetle readily responds to fresh pine sap (resin) associated with injured trees... are not usually a serious problem. They are most commonly found in stumps and injured residual trees following logging... the attacks of this beetle are usually limited to the bottom six to eight feet of the trunk of the pine tree and a large mass of pitch or resin will usually form where they attack... the first sign of attack by engraver beetles is the presence of boring dust in the crevices of the bark or on the ground. Also, it is a good idea to remove some bark from a recently-attacked tree to look for the distinct gallery pattern made by the adult bark beetle.
