The effects of herbivore-induced plant volatiles on interactions between plants and flower-visiting insects

► Plants are exposed to many attackers and herbivorous insects take a prominent place. ► Plants have evolved a high diversity of secondary metabolites that mediate defences. ► A central paradigm in plant biology is the trade-off between growth and defence. ► Herbivore-induced plant volatiles (HIPV) mediate induced indirect defence. ► We review how HIPV affect interactions between plants and flower-visiting insects.
