The headspace volatiles emitted by leaves of 4 host tree species with different resistant abilities to Anoplophora glabripennis were examined by adsorption thermodesorption and GC MS identification. Fifty six compounds were yielded, including alcohols, aldehydes, esters, terpenoids and carboxylic acids. The analysis revealed that the resistant host trees of A. glabripennis released more alcohols and aldehydes, while the susceptible host trees released more esters and terpenoids. Lots of terpenes were released and the releasing of aldehydes and alcohols were also enhanced when those trees were artificially damaged. The variations of the releasing of these volatile compounds may be relevant to the feeding habit of A. glabripennis.
