Pine shoot beetle
The pine shoot beetle (Tomicus piniperda) attacks new shoots of pine trees, which stunts the growth of the trees. The pine shoot beetle (PSB) might also attack stressed pine trees by breeding under the bark at the base of the trees. The beetles can cause severe decline in the health of the trees, and in some cases, kill the trees when high populations exist.
In states regulated under the current United States Department of Agriculture quarantine, the beetle has been found in pine tree production areas, Christmas tree farms, nurseries, mature pine stands and areas surrounding mill yards that process pine logs. Pine trees make up a significant percentage of landscape trees and Christmas tree farm production.
