植物对各种各样的食草动物表现出多样性的防御策略。响应于食草动物的挥发物的特定混合物（HIPVs -食草动物诱导的植物挥发物）的排放在通过吸引食草动物的天敌和引发其邻近的植物来间接保护植物方面起着巨大的生态作用，所述植物可以在“接收者”植物上引起较差的觅食生境。玉米植株表现出包括单萜、倍半萜、高萜、绿色叶挥发物和吲哚在内的挥发物的混合物的诱导，以响应专门的食草动物粘虫。同种植物放置在下风处的受侵染的玉米植株暴露于HIPVs后，幼虫发育减少，相比那些暴露于未受侵染的植物挥发物。这些研究结果表明，暴露于HIPV的玉米植物引发这些植物增强防御反应的专业草食动物的禾本科。
Plants show a diversity of defense strategies against a wide range of herbivores. The emission of a specific blend of volatiles in response to herbivory (HIPVs - herbivore-induced plant volatiles) plays a great ecological role in indirect protection of the plants by attracting natural enemies of herbivores and priming their neighboring plants that can cause poorer foraging habitats on the 'receiver' plants. Maize plants showed induction of a blend of volatiles including monoterpenes, sesequiterpenes, homoterpenes, green leaf volatiles, and indole, in response to the specialist herbivore Mythimna separata. Conspecific plants placed downwind of infested maize plants showed reduced larval development after exposure to HIPVs, compared to those exposed to volatiles from uninfested plants. These findings indicate that exposure of maize plants to HIPVs primed these plants for enhanced defense responses to specialist herbivores of Poaceae.
