Aphids severely affect crop production by transmitting many plant viruses. Viruses are obligate intracellular pathogens that mostly depend on vectors for their transmission and survival. A majority of economically important plant viruses are transmitted by aphids. They transmit viruses either persistently (circulative or non-circulative) or non-persistently. Plant virus transmission by insects is a process that has evolved over time and is strongly influenced by insect morphological features and biology. Over the past century, a large body of research has provided detailed knowledge of the molecular processes underlying virus-vector interactions. In this review, we discuss how aphid biology and morphology can affect plant virus transmission. © 2021 Society of Chemical Industry.

蚜虫生物学和形态对植物病毒传播的影响

蚜虫通过传播许多植物病毒严重影响作物生产。病毒是专性的细胞内病原体，它们的传播和生存主要依赖于载体。大多数经济上重要的植物病毒是由蚜虫传播的。它们持续（循环或非循环）或非持续传播病毒。昆虫传播植物病毒是一个随时间演变的过程，并受到昆虫形态特征和生物学的强烈影响。在过去的一个世纪中，大量研究提供了有关病毒-载体相互作用的分子过程的详细知识。在这篇综述中，我们讨论了蚜虫的生物学和形态如何影响植物病毒的传播。© 2021 化学工业协会。
