摘要: 大部分植物病毒需要介体来传播,而昆虫则是其最重要的介体类别。植物-病毒-介体昆虫的互作关系既复杂又特异,而病毒由于其繁殖迅速、变异快而成为三者协同进化的推动者,以有利于病毒的有效传播。病毒对介体昆虫的影响分直接影响和间接影响两个方面,间接影响即是病毒侵染寄主植物后会引起植物的光合作用、次生代谢、营养成分、信号途径等发生变化,继而影响介体昆虫的寄主选择行为、生长发育、繁殖力等生物学特性,最终会影响介体对于病毒的传播。综述了病毒侵染寄主植物对刺吸式昆虫生物学特性的影响,以期为防治植物病毒性病害提供依据。

Abstract: Most plant viruses are transmitted by vectors,among which insect is the most important category. The tripartite interaction of plant-virus-vector is complex and specific. So far,virus has become a powerful booster for co-evolution of plant-virus-vector due to its rapid reproduction and fast variation,which then is conducive for its effective transmission. The effects of virus on vector insects can be direct and indirect. The indirect effect refers to such process,i.e.,virus infection to host plants results in the changes on the photosynthesis,secondary metabolism,nutrition components,and signal pathways of plants,which thus affects insects’ biological properties,such as their behavior of host selection,growth and development,fertility and so on,and finally influences virus’ transmission efficiency. The biological impacts of virus-infected host plants on piercing-sucking insects are reviewed here,aiming at providing evidences for the prevention and control of plant virus diseases.
