Description: The Jeffrey pine beetle (Dendroctonus jeffreyi Hopk.), one of the bark beetles that kill trees by mining between the bark and the wood, is the principal insect enemy of Jeffrey pine. The beetle is of economic importance chiefly in California, where most of the Jeffrey pine grows, and is most destructive in old-growth stands in the timber-producing areas of northeastern California. It also causes a great deal of damage to forests reserved for recreational use, such as those in the national parks.
