摘　　要：本文综述了植物—植食性昆虫—天敌三重营养关系中的化学信息联系,昆虫通过植物释放的挥发性化学物质来定位,植物在受到植食者危害后一方面产生生理和生物学的变化来抵御侵害,另一方面通过释放互益素吸引天敌来阻止植食者的继续危害。信息化学物质在三重营养关系中发挥着重要作用。This paper reviewed the chemical communication among plant, herbivore and natural enemy. Herbi- vores located sites by the volatile substance released by plants. After disturbed by herbivores, plants usually exhibits physiological and biological change to resist damage. On the other hand, plants attracted natural enemies to prevent further disturbance by releasing chemical substance. The chemical substances plays important roles in relationships amog three tritrophie levels.
