Table 2 Composition of volatiles collected by SPME from Pinus pinaster before (control) and during Monochamus galloprovincialis feeding (B Mg F and D Mg F, respectively). The average percentage is given for each component for the total trees analysed, or for the same trees grouped by their chemotypes. For trees from each chemotype, see Table 1.
