植物可能对食草性昆虫的取食和产卵都有反应。虽然在过去的几十年里，植物对食草动物取食损害的反应已经被深入研究，但很少有研究考虑植物对食草性昆虫卵沉积的反应，但越来越多的研究考虑了植物对食草性昆虫卵沉积的反应。对食草动物产卵表现出防御性反应的植物不会等到被取食破坏，而是可能会对食草动物攻击的初始步骤之一--卵沉积--做出反应。植物对取食的直接防御反应直接作用于食草动物的取食阶段。然而，植物也可以通过(A)肿瘤的形成，(B)坏死组织的形成(=超敏反应)和(C)产卵威慑物质的产生，对卵沉积表现出直接的防御反应。所有这些植物反应对卵、孵化的幼虫或产卵的雌性都有直接的负面影响。植物对取食的间接防御反应导致挥发物的释放，这些挥发物吸引取食阶段的捕食者或寄生蜂。最近的一些研究表明，植物也能够释放挥发物来响应卵的沉积，这些挥发物会吸引卵寄生蜂。对卵沉积诱导同系物的机制的研究表明，与通过取食伤害诱导植物反应的机制有几个相似之处。当从进化的角度考虑诱导植物对食草动物的防御时，问题就出现了，食草动物是否进化出了绕过甚至利用植物防御反应的能力。比较了食草动物对产卵诱导的植物反应和它们对取食诱导的植物反应的反应。
Plants may respond both to feeding and oviposition by herbivorous insects. While responses of plants to feeding damage by herbivores have been studied intensively during the past decades, only a few, but growing number of studies consider the reactions of plants towards egg deposition by herbivorous insects. Plants showing defensive response to oviposition by herbivores do not 'wait' until being damaged by feeding, but may instead react towards one of the initial steps of herbivore attack, the egg deposition. Direct plant defensive responses to feeding act directly against the feeding stages of the herbivores. However, a plant may also show direct defensive responses to egg deposition by (a) formation of neoplasms, (b) formation of necrotic tissue (= hypersensitive response), and (c) production of oviposition deterrents. All these plant reactions have directly negative effects on the eggs, hatching larvae, or on the ovipositing females. Indirect plant defensive responses to feeding result in the emission of volatiles ( = synomones) that attract predators or parasitoids of the feeding stages. A few recent studies have shown that plants are able to emit volatiles also in response to egg deposition and that these volatiles attract egg parasitoids. Studies on the mechanisms of induction of synomones by egg deposition show several parallels to the mechanisms of induction of plant responses by feeding damage. When considering induced plant defence against herbivores from an evolutionary point of view, the question arises whether herbivores evolved the ability to circumvent or even to exploit the plant's defensive responses. The reactions of herbivores to oviposition induced plant responses are compared with their reactions to feeding induced plant responses.
