In response to feeding by arthropods, plants actively and systemically emit various volatile substances. It has been proposed that these herbivore-induced volatiles (HIPVs) can be exploited in agricultural pest control because they might repel herbivores and because they serve as attractants for the enemies of the herbivores. Indeed, recent studies with transgenic plants confirm that odour emissions can be manipulated in order to enhance the plants' attractiveness to beneficial arthropods. An additional advantage of manipulating HIPV emissions could be their effects on neighbouring plants, as a rapidly increasing number of studies show that exposure to HIPVs primes plants for augmented defence expression. Targeting the right volatiles for enhanced emission should lead to ecologically and economically sound ways of combating important pests.
作为对节肢动物取食的响应，植物会主动且系统性地释放各种挥发性物质。有人提出，这些由食草动物诱导产生的挥发性物质（HIPVs）可用于农业害虫防治，因为它们可能驱避食草动物，还因为它们可作为食草动物天敌的引诱剂。的确，近期对转基因植物的研究证实，可以通过控制气味释放来提高植物对有益节肢动物的吸引力。控制HIPV释放的另一个优势可能在于其对邻近植物的影响，因为越来越多的研究表明，接触HIPVs能使植物做好增强防御反应的准备。针对合适的挥发性物质来增强释放量，应能找到生态和经济上合理的方法来对抗重要害虫。
