#Unit 6. System Physiology – Plant

Many plants release a specific bouquet of volatile organic compounds when attacked by insect herbivores. These volatiles can consist of compounds from all major pathways for secondary metabolites including terpenoids (mono- and sesquiterpenes), alkaloids (indole), and phenylpropanes (methyl salicylate), as well as green-leaf volatiles.

These VOCs are herbivore– induced plant volatiles (HIPV) HIPV and act as cues for natural enemies of the insect herbivore, for example parasitic wasps.
