摘　　要：自世界工业革命以来,化石燃料的大量使用以及人类对自然环境的过度破坏,致使大气CO2浓度不断升高.研究大气CO2浓度升高介导的农业生态系统内植物、植食性昆虫及其天敌的适应机制,对于阐明气候变化下农业害虫爆发危害规律,指导防控与减排具有重要意义.本文综述了大气CO2浓度升高对农业生态系统中植物、植食性昆虫及天敌的影响,主要包括:1)相关研究方法的改进;2)大气CO2浓度升高介导的寄主植物营养和次生代谢物质的变化;3)大气CO2浓度升高对以植物为食的昆虫的个体生长发育、种群数量、行为的影响;4)天敌昆虫的生物学及捕食量与寄生率变化.最后对今后的研究方向进行了展望.Since the industrial revolution, the huge consumption of fossil fuels and unduly destruc- tion of natural habitats by human activities have led to the ever-increasing concentration of atmos- pheric CO2. To study the adaptation mechanisms of plant, herbivorous insect, and its natural ene- my within agricultural ecosystems to the elevated atmospheric CO2 concentration is of significance in deciphering the damage pattern of agricultural pest occurrence and controlling the pest occurrence and in mitigating the CO2 emission from agricultural ecosystems. This paper reviewed the research progress on the effects of elevated atmospheric CO2 on the host plant, herbivorous insect, and its natural enemy in agro-ecosystem, with the focuses on the improvement of rela-ted research meth- ods, the variation patterns of host plant primary and secondary metabolites induced by elevated at- mospheric CO2, the effects of the elevated CO2 on the growth and development, population density, and behaviors of herbivorous insect, and the biology and predation and/or parasitism rates of natural enemy. The future research frontiers in this research area were also discussed.
