Are all pine trees susceptible to pine bark beetle?
Yes and no, while no tree is beetle proof there are certain species of pine that are less likely to become infested and die from pine bark beetles. Loblolly (Pinus taeda) and shortleaf pines (Pinus echinata) are highly susceptible to pine bark beetles and rarely survive an infestation. Longleaf (Pinus palustris) and slash pines (Pinus elliottii), however, are more resistant to pine bark beetles due to their higher sap flow, which helps repel beetles by expelling them from the tree with sap. Due to drought and lower sap flows even longleaf is having problems surviving beetle attacks and should be closely monitored in the rare case it is attacked. What kind of pine beetle do I have? Several species of bark beetles affect pines in Baldwin County. These include Black Turpentine Beetle (BTB), Ips engraver beetles, and Southern Pine Beetle (SPB). Attacks in pines south of Bay Minette are probably from Black Turpentine Beetles (BTB) or Ips engraver beetles. Additionally, for homeowner managem
