Advances in herbivore-induced plant volatiles (HIPVs) as plant defense and application potential for crop protection
Author(s): Haftay Gebreyesus Gebreziher
Abstract: Herbivore-induced plant volatiles (HIPVs), which are released when plants are attacked by herbivores, play important roles in plant defense through direct defense or change in behavior of lower and higher trophic level arthropods (indirect defense) mainly by recruiting arthropod natural enemies to herbivore-attacked plants. Plethora of investigations has explored the attractiveness of HIPVs to arthropod natural enemies. Natural enemies such as arthropod parasitoids and predators utilize HIPVs to locate and feed or parasitize their prey or host and by recruiting these mutualistic, the plant gets protection against antagonist herbivores. However, beyond the function in tritrophic interaction, utilization of HIPVs for crop protection is yet recently a focus of researchers from many disciplines. In this paper, we reviewed the function of HIPVs for plant defense and the possibilities of utilizing HIPVs for crop protection.
