The most contiguous populations occur in the southern states, especially in the range of shortleaf pine. Prevention relies on forest management practices, like thinning, to promote vigorous trees and healthy forests that are consequently inhospitable to SPB. In the late 1990s, after several relatively warm winters, a massive outbreak resulted in the loss of millions of hectares of pine forest in British Columbia over the next 15 years.

There are four methods used in direct suppression of southern pine beetle: salvage removal, cut-and-leave, pile-and-burn, and chemical insecticides (Swain and Remion, 1981). Trees are often mass attacked by thousands of individual southern pine beetles. Similar to the evolving impacts of wildfire, these factors work in concert to make SPB a greater threat than ever. To combat such losses, pest control methods were developed that were highly effective in protecting trees but not always beneficial to other forest values. The SPB causes significant and rapid economic losses in all forest types, including traditional forests, urban forests, watersheds and viewsheds, and negatively impacts habitat for endangered species and recreational areas.

Due to limited historical records, they have not previously been recorded on the northeastern slopes of the Rocky Mountains. The small beetles will mass together and attack a tree as one coordinated force, overcoming the tree’s defenses and ability to “pitch out” the attacking beetles. Public outcries against the use of toxic chemicals in the forest resulted in the banning of several pesticides and challenged researchers and managers to develop and use more environmentally friendly methods for controlling forest pests. Loblolly, shortleaf, pitch, pond, and Virginia pines are the favored host tree species. Can anyone help me?
