New introduction in California: the redhaired pine bark beetle, Hylurgus ligniperda Fabricius

Abstract

An overwintering North American population of the redhaired pine bark beetle (RPBB) was first discovered in November 2000 in Rochester, New York. In July 2003 it was also detected at two locations in Los Angeles County, California near heavily urbanized areas where exotic pines of Mediterranean origin are favored landscape trees. California and New York currently have the only known established populations of RPBB in North America. The beetle feeds in the phloem of the basal portion of pine stems, large roots, or woody debris on the soil surface.
