Evolutionary stability of obligate pollination mutualism mediated by diverse fruit-infesting insect community

有机体之间的互惠关系最好被看作是自私的相互作用，尽管如此，它会给每一个伙伴带来净利益。然而，互惠关系很容易受到个体的入侵，这些个体过度利用利益而付出较少的成本，最终导致互惠关系的崩溃。在本研究中，我以植物-传粉者的共生关系作为模型系统，提出第三方生物（传粉者的拟寄生虫）可以防止传粉者的过度利用，从而有助于共生关系的长期稳定。

Mutualistic relationships between organisms are best views as selfish interactions that nonetheless result in net benefit to each patner. However, mutualisms are vulnerable to invasion by individuals that overexploit the benefit while paying less of the cost, which eventually leads to the collapse of the mutualism. In this study, I used plant-pollinator mutualism as a model system and suggested the possibility that a third-party organism (parasitoid of the pollinator) can prevent overexploitation by the pollinator, thereby contributing to the long-term stability of the mutualism.
