Photograph by Bruce Smith, USDA AHPIS PPQ, www.forestryimages.org. APHIS, in consultation with the National Plant Board, considers pine shoot beetle to be a minor pest that can be controlled locally, given its slow spread and the minimal damage it causes. The PSB and associated fungi can cause the quality of timber to deteriorate, resulting in negative implications for industries relying on high quality wood.
