Plant-mediated interactions between begomoviruses and whiteflies exert important influences on the population dynamics of vectors and the epidemiology of plant diseases. In this article, we synthesize the relevant literature to identify patterns to the interactions. We then review studies on the ecological, biochemical and molecular mechanisms underlying the interactions and finally elaborate on the most interesting issues for future research. The interactions between begomoviruses and the insect vector, the whitefly Bemisia tabaci, via their shared host plants can be mutualistic, neutral or negative. However, in contrast to a pattern of improved performance of vectors on virus-infected plants that has been observed with persistently transmitted RNA viruses, the number of cases exhibiting mutualistic, neutral or negative effects in the indirect interactions between begomoviruses and whiteflies appear evenly distributed. With regard to the mechanisms of plant-mediated positive effects on whiteflies, two case studies indicate that suppression of plant defence and/or alteration in plant nutrition as a result of virus infection can be important. Our review shows that we are only just beginning to understand the tripartite interactions between begomoviruses, whiteflies and plants. Future efforts in this area should try to expand the number and diversity of pathosystems for investigation to reveal the patterns of interactions, to investigate the molecular and biochemical mechanisms of the interactions using a multidisciplinary approach, and to examine the virus-plant-vector interactions in the field and in natural plant communities.
植物介导的双生病毒与粉虱之间的相互作用对介体种群动态和植物病害流行病学具有重要影响。在本文中，我们综合相关文献来确定相互作用的模式。然后，我们回顾了关于这些相互作用背后的生态、生化和分子机制的研究，最后阐述了未来研究中最有趣的问题。双生病毒与昆虫介体烟粉虱通过它们共同的寄主植物发生的相互作用可能是互利的、中性的或负面的。然而，与在持久性传播的RNA病毒中观察到的介体在病毒感染植物上表现出性能提高的模式不同，在双生病毒与粉虱的间接相互作用中，表现出互利、中性或负面影响的案例数量似乎分布均匀。关于植物介导的对粉虱的积极影响机制，两个案例研究表明，病毒感染导致的植物防御抑制和/或植物营养改变可能很重要。我们的综述表明，我们才刚刚开始理解双生病毒、粉虱和植物之间的三方相互作用。该领域未来的工作应努力扩大用于研究的病理系统的数量和多样性，以揭示相互作用的模式，采用多学科方法研究相互作用的分子和生化机制，并在田间和自然植物群落中研究病毒-植物-介体相互作用。
