In return, natural enemies (predators and parasitoids) respond to these emitted herbivore-induced plant volatiles while foraging for their hosts. Neighboring plants of the same family may be induced by the emitted HIPVs. This is a tritrophic interaction that leads to an ‘indirect’ plant defense characteristic within species that recruit the natural enemies to ward off pests. The objective of this study was to evaluate the effect of HIPVs of B. brizantha on neighbouring maize plants on the management of Chilo partellus. This was done by entrainment of volatiles 341
