HOW TO APPLY
BENEFITS
Bark beetle is the common name for the beetle subfamily Scolytinae. The term "bark beetle" refers to the fact that many species feed on the inner layer of bark (phloem) of trees. Well-known species are members of the Scolytus-like genus, such as the mountain pine beetle Dendroctonus ponderosae, the southern pine beetle Dendroctonus frontalis, and their close relatives are major pests of coniferous forests in North America.
