Abstract

Genetic techniques have yielded new insights into plant-herbivore coevolution. Quantitative genetic tests of herbivory theory reveal that in some cases insect herbivores impose selection on resistance traits. Also, some resistance traits are costly while others appear not to be, and genetic models can explain these results. Genetic variation in plant resistance influences insect community structure by modifying interactions of herbivores with competitors and natural enemies. Therefore, models of multispecies coevolution are more realistic than pairwise coevolutionary models. Ecological genetics will facilitate further theoretical and empirical exploration of multispecies coevolution of plants and herbivores.

摘要

遗传技术为植物-草食动物协同进化提供了新的见解。对草食性理论的定量遗传测试表明，在某些情况下，昆虫草食动物对抗性特征施加了选择压力。此外，一些抗性特征是有代价的，而另一些则似乎没有，遗传模型可以解释这些结果。植物抗性的遗传变异通过改变草食动物与竞争者和天敌的相互作用来影响昆虫群落结构。因此，多物种协同进化模型比成对协同进化模型更现实。生态遗传学将促进对植物和草食动物多物种协同进化的进一步理论和实证探索。
