Bark beetles are the most destructive insects affecting pines in the southern United States. Greatest losses occur in loblolly and shortleaf pine stands, although most of the 11 native pines in the South are attacked. To be effectively dealt with, any pest (or pests) must first be identified. This handbook provides the reader with information to distinguish between the five southern pine bark beetle species based on symptoms of attack, adult appearance, and differences in life cycles and behaviour.
