植物、食草动物和食草动物天敌之间的三营养相互作用对于确定自然生态系统和管理生态系统中生物的丰度和分布具有重要意义。这些相互作用的复杂性的理解已经大大增长，因为价格等。（1980）写了一篇关于这个主题的开创性评论。特别是，植物与草食动物的相互作用在影响第三营养级中所起的作用越来越受到关注（Takabayashi &迪凯，1996; Agrawal & Rutter，1998; Thaler，1999）。被食草动物侵染的植物会释放出一些线索，这些线索可以为周围群落中的食草动物、捕食者和寄生虫提供信息。越来越多的理论和实验室证据表明，食草动物会避开食草动物出没的植物，捕食者会避开捕食者出没的植物，而寄生虫会被食草动物出没的植物所吸引（Janssen等人，1995，1997; Turlings等人，1995; Karban和Baldwin，1997; Pallini等人，三养相互作用可能部分由植物±食草动物复合体发出的气味或挥发物介导。例如，许多实验已经证明，食草动物损害的植物释放吸引食草动物的天敌的特定挥发性化学物质（Sabelis &货车de Baan，1983; Takabayashi &迪凯，1996; De Moraes等人，1998年）。单独的植物、单独的食草动物和机械损伤的植物通常比食草动物侵染的植物对食草动物的天敌的吸引力小。这种相互作用的普遍性和在农业中利用它们的潜力取决于它们在田间条件下在许多系统中起作用的事实。最近的一些实地研究已经证明，受损的植物会吸引天敌（Drukker等人，1995; Shimoda等人，1997; Agrawal，1998 a; De Moraes等人，1998; Agrawal & Dubin-Thaler，1999）。
Tri-trophic interactions among plants, herbivores, and natural enemies of herbivores are important in determining the abundance and distribution of organisms in natural and managed ecosystems. Understanding of the complexity of these interactions has grown tremendously since Price et al.(1980) wrote a seminal review of the topic. In particular, the role that the plant±herbivore interaction plays in affecting the third trophic level is of growing interest (Takabayashi & Dicke, 1996; Agrawal & Rutter, 1998; Thaler, 1999). Plants infested with herbivores release cues that can provide information to herbivores, predators, and parasitoids in the surrounding community. A growing body of theory and laboratory evidence suggests that herbivores avoid herbivoreinfested plants, predators avoid predator-infested plants, and parasitoids are attracted to herbivore-infested plants (Janssen et al., 1995, 1997; Turlings et al., 1995; Karban & Baldwin, 1997; Pallini et al., 1997).Tri-trophic interactions may be mediated in part by odours or volatiles given off by the plant±herbivore complex. For example, many experiments have demonstrated that herbivoredamaged plants release particular volatile chemicals that attract natural enemies of herbivores (Sabelis & van de Baan, 1983; Takabayashi & Dicke, 1996; De Moraes et al., 1998). Plants alone, herbivores alone, and mechanically damaged plants are often less attractive to natural enemies of herbivores than are herbivore-infested plants. The generality of such interactions and the potential to exploit them in agriculture relies on the fact that they are operative in many systems under field conditions. A few recent field studies have documented that damaged plants attract natural enemies (Drukker et al., 1995; Shimoda et al., 1997; Agrawal, 1998a; De Moraes et al., 1998; Agrawal & Dubin-Thaler, 1999).
