The Asian ambrosia beetle, Xylosandrus crassiusculus, is an exotic species first detected in South Carolina in the early 1970's. Since then it has spread from Texas to New Jersey and has become a very important pest or ornamental trees in the nursery and landscape. Several new techniques to manipulate the beetle's behavior have been developed recently by the authors. As a result, some new knowledge about the behavior, biology, and management of the beetle will be discussed.
