Summary Herbivore‐induced plant volatiles (HIPVs) are known to be perceived by neighboring plants, resulting in induction or priming of chemical defenses. There is little information on the defense responses that triggered these plant–plant interactions, and phenomenon has rarely been studied rice. Using molecular analyses combination with insect behavioral performance experiments, we how emitted rice plants infested striped stemborer (SSB) Chilo suppressalis affect defenses against this pest conspecific plants. Compared exposed from uninfested SSB‐induced showed enhanced direct indirect resistance SSB. When subjected caterpillar damage, HIPV‐exposed increased expression jasmonic acid (JA) signaling genes, JA accumulation higher levels defensive proteinase inhibitors. Moreover, larger amounts inducible were more attractive parasitoid Cotesia chilonis . By unraveling factors involved HIPV‐mediated rice, reveal a key role for These findings pave way novel management strategies enhance plant's one its most devastating pests.
