摘　　要：由于全球气候变化,CO_2浓度升高对生态系统产生的影响已成为国际关注的焦点。媒介昆虫传毒引起的植物病毒病是农业生产的一个重要影响因素之一。"CO_2-植物-媒介昆虫-病毒"是一个复杂的系统,围绕CO_2浓度升高对植物的影响、CO_2浓度升高对"植物-媒介昆虫"相互关系以及CO_2浓度升高对媒介昆虫及其传播病毒发生的影响已开展了大量研究。本文主要从CO_2浓度升高对植物、CO_2浓度升高对媒介昆虫和植物以及CO_2浓度升高对媒介昆虫所传病毒发生等方面阐述CO_2浓度升高对媒介昆虫及所传植物病毒发生的影响。研究表明,CO_2浓度升高对于媒介昆虫和病毒本身的直接影响较小,主要影响植物初级和次生代谢过程,主要通过引起植物在基因表达、生理生化、营养水平以及生长等各个层面的变化来影响植物,从而通过级联效应改变"植物-媒介昆虫-病毒"之间的互作关系。Elevation in atmospheric CO2 concentration is predicted to impact both current and future ecosystems and consequently is now a subject of great scientific interest. Plant viral diseases are a limiting factor on agricultural productivity. The “CO2-plant-insect vector-virus” system is complex, and there have been many studies focused on the impacts of increased atmospheric CO2 on plant or “plant-herbivore” interactions, and on the spread of plant viruses. This paper reviews the impact that higher CO2 concentrations may have on the incidence and spread of plant viruses, its potential effects on plant and virus/plant interactions, and on insect vectors. Changes in host plants （gene expression profiles, physiology and biochemistry, nutrition and growth） that might result from elevated CO2 could affect the “plants-herbivore arthropods-plant virus” complex via cascading effects, but the direct effect of elevated CO2 levels on insect vectors and viruses is predicted to be very small.
