Inhibition of feeding by a generalist insect due to increased volatile leaf terpenes under nitrate-limiting conditions.

abstract：:Herbivore-induced plant volatiles (HIPVs) are important cues for natural enemies to find their hosts. HIPVs are usually present as blends and the effects of combinations of individual components are less studied. Here, we investigated plant volatiles in a tritrophic system, comprising the parasitoid wasp Lytopylus ruf...
