Another Asian ambrosia bark beetle, Xyleborinus artestriatus (Eichhoff) (Coleoptera: Curculionidae: Scolytinae), found in the United States. Pan-Pacific Entomologist. 89(1):27-31. Interpretive Summary: Ambrosia bark beetles can be economic pests of forest, urban, and commercial tree stands by drilling pin holes that degrade the timber, and by vectoring a fungus that can weaken or kill the host. This publication reports on the first North American records of an ambrosia bark beetle that originated in Asia, and provides host information, as well as characters and images to allow its proper identification. This information will be of use to scientists, regulators and other workers interested in monitoring and controlling potential pest problems of economically important trees.
Technical Abstract: Xyleborinus artestriatus (Eichhoff), an ambrosia beetle native to Asia, is reported for the first time in North America based on specimens from Georgia and Texas. This is the twenty-fourth species of exotic Xyleborina documented in North America. North American distributional records, key identification characteristics, morphological variability, and a brief history of the systematics are presented.
