Following an herbivore attack plants can reduce damage by inducing a wide variety of highly specific chemical and physical defences. Plants are able to recognize, integrate and respond accordingly in a specific manner to the biotic stimuli provoked by different herbivore species. This specificity of induced defences is particularly important for long-lived plants (e.g. pines) which have to face against multiple biological aggressions during their life cycle. In this sense, it has been recently documented that induction of mono- and sesquiterpenes (the volatile fraction of oleoresin) in pine trees is specific to plant species, herbivore identity and plant tissue. However, much less attention has been paid to understand the sources of phenotypic variation of diterpenes, the non-volatile fraction of oleoresin that seals the wounds after oxidization.
