Overall, we thus show that the induction of volatile and non-volatile leaf metabolites showed different levels of specificity. The specificity in volatiles could potentially serve as an important cue to specialized predators or parasitoids, increasing the efficacy of volatiles as indirect defences. In contrast, the induction of non-volatile leaf metabolites was largely unaffected by herbivore identity. Most non-volatile metabolites were downregulated, possibly indicating that plants redirected their resources from leaves in response to herbivory. Our results demonstrate how diverse responses to herbivores can contribute to the diversity of plant defensive strategies.
