Detailed explanation-1: -The southern pine beetle (SPB), Dendroctonus frontalis, is considered the most destructive native forest pest in the Southern U.S., the SPB can occasionally reach outbreak levels in pine forests in Virginia.
Detailed explanation-2: -It has been estimated that 90% of insect-caused tree mortality in the United States is due to bark and ambrosia beetles, making them the most destructive insects in western conifer forests.
Detailed explanation-3: -Pitch canker is caused by the fungus Fusarium lateritiwn var. pini. This fungus attacks many conifer species including shortleaf, slash, longleaC pitch, Scotch, and Table mountain pine but it is particularly prevalent on Virginia pine.
Detailed explanation-4: -MPB impacted nearly 3.4 million acres in the state from 1996 to 2014, but populations now remain at endemic, or background, levels statewide. Infestations in both ponderosa and limber pines continued at moderate to low levels in the northern and central Sangre de Cristo Mountains.
