Male white-spotted longicorn beetles Anoplophora malasiaca raised on willow Salix schwerinii were preferentially attracted to the odour of wounded S. schwerinii branches when released near a female model in the laboratory. This attractiveness rapidly decreased within 2 h after wounding. Solid phase microextraction and subsequent gas chromatography analyses of volatiles from the wounded branches detected three highly volatile monoterpenes: 1,8-cineole, nerol and geraniol. Among the monoterpene compounds, nerol showed a significant attractiveness to the male beetles raised on Salix. Sesquiterpene hydrocarbons, which have been identified as attractants for a beetle population raised on citrus, were detected only in trace amounts in S. schwerinii branches. These results suggest that beetles raised on these two hosts use different odour cues for mate location.
