植物通过多种方式保护自己免受食草动物的侵害，包括产生空气中的挥发性有机化合物（VOC）。这些挥发性有机化合物通过吸引食草动物的天敌而使植物受益。豌豆蚜，Acyrthosiphon pisum，能够在其寄主植物蚕豆上取食，而不会引起植物VOC排放的可检测的变化。VOCs排放水平没有显着不同的控制植物和蚜虫喂养长达5天。使用第二草食动物，甜菜夜蛾毛虫，甜菜夜蛾，我们证明了几个预期的毛虫诱导的挥发性有机化合物减少时，共感染豌豆蚜虫，从而证明豌豆蚜虫有能力抑制某些挥发性有机化合物的释放。该研究首次表明，蚜虫不仅能避免触发植物挥发物的释放，而且能主动抑制植食性昆虫诱导的挥发物。
Plants defend themselves against herbivory through several means, including the production of airborne volatile organic compounds (VOCs). These VOCs benefit plants by attracting natural enemies of their herbivores. The pea aphid, Acyrthosiphon pisum, is able to feed on its host plant, Vicia faba, without inducing detectable changes in plant VOC emission. Levels of VOCs emission are not significantly different between control plants and those fed upon by aphids for up to 5 days. Using a second herbivore, the beet armyworm caterpillar, Spodoptera exigua, we demonstrate that several expected caterpillar-induced VOCs are reduced when co-infested with pea aphids, thus demonstrating that pea aphids have the ability to inhibit the release of certain VOCs. This study shows, for the first time, that aphids not only avoid triggering plant volatile emission, but also can actively inhibit herbivore-induced volatiles.
