The lima bean plant does this as an induced defense when being eaten by herbivorous predators. It is the mechanical wounding and chemical elicitors from insect oral secretions that first begin the signaling pathway to induce HIPV production. Once this pathway is induced, the plant produces HIPVs which are released in to the air and can be received by any organisms that have receptors capable of receiving HIPVs, which includes: carnivores, conspecific and heterospecific herbivores, as well as neighboring plants. It is this signaling of the carnivorous natural enemy of herbivores that is of particular interest, as they become attracted to the plant and will then come and prey upon the plant's herbivorous enemy, thereby reducing herbivory of the plant.
