蚜虫是多种病毒的宿主，也是植物病原体的重要载体。蚜虫的运动和行为严重影响病毒的传播。因此，翅膀的可塑性（个体可以根据环境条件有翼或无翼）是蚜虫相关病毒传播的一个重要因素。我们回顾了几个令人着迷的系统，其中蚜虫载体植物病毒与蚜虫翅膀可塑性相互作用，间接地通过操纵植物生理学和直接通过与可塑性途径的分子相互作用。我们还介绍了最近蚜虫特异性病毒和蚜虫基因组内的内源性病毒元素影响翅膀形成的例子。我们讨论了为什么具有不同传播模式的不相关病毒会趋同进化来操纵蚜虫的翅膀形成，以及这是否对宿主和病毒都有利。我们认为，与病毒的相互作用很可能塑造了蚜虫物种内部和物种之间翅膀可塑性的进化，我们讨论了这些发现对蚜虫生物防治的潜在重要性。
Aphids are hosts to diverse viruses and are important vectors of plant pathogens. The spread of viruses is heavily influenced by aphid movement and behaviour. Consequently, wing plasticity (where individuals can be winged or wingless depending on environmental conditions) is an important factor in the spread of aphid‐associated viruses. We review several fascinating systems where aphid‐vectored plant viruses interact with aphid wing plasticity, both indirectly by manipulating plant physiology and directly through molecular interactions with plasticity pathways. We also cover recent examples where aphid‐specific viruses and endogenous viral elements within aphid genomes influence wing formation. We discuss why unrelated viruses with different transmission modes have convergently evolved to manipulate wing formation in aphids and whether this is advantageous for both host and virus. We argue that interactions with viruses are likely shaping the evolution of wing plasticity within and across aphid species, and we discuss the potential importance of these findings for aphid biocontrol.
