In the United States, the Asian longhorned beetle (Anoplophora glabripennis) is an invasive, exotic pest of hardwoods, including maples, poplars and willows. Originally from Asia, the beetle has established populations in New York City and Chicago. Potential damage in the United States is estimated at over 500 billion dollars. The management of this insect would be significantly enhanced by a chemical attractant for survey and detection work. In 1997, volatiles produced by host materials and beetles were isolated and identified. Subsequently, one beetle-produced and several host volatiles have elicited electrophysiological responses in male A. glabripennis antennae. In laboratory, paired choice tests, male beetles preferentially selected females and host volatiles over blanks. Frass extracts have also been tested for similar volatile production and behavioral responses. In field tests, both males and females were attracted to synthetic host compounds. In 1999, cis-3-hexen-1-ol baited traps attracted a significantly higher number of beetles then unbaited traps. In 2000, cis-3-hexen-1-ol also attracted a significantly higher number of beetles. Traps baited individually with 1-butanol, 1-pentanol, or 2-pentanol caught few beetles, but the combination of the three compounds attracted significantly more beetles than all other treatments, including cis-3-hexen-1-ol. The 2001 field tests showed similar trends but without statistical significance. Long-term applications of this research include the development of a semiochemical-based control method for A. glabripennis and the development of a monitoring system to evaluate the progress and effectiveness of this and other control methods.
