中文摘要：

      大气二氧化碳浓度升高及其伴随的全球变暖引起国内外科学家的极大关注。CO₂浓度升高主要通过改变植物的初级和次级代谢产物，影响以之为食的昆虫。本文结合作者近年来的研究成果，着重于以CO₂浓度升高为作用因子，以植物和植食性昆虫的相互关系为对象，比较了咀嚼式口器昆虫与刺吸式口器昆虫对大气CO₂浓度升高的响应特征，分析了不同取食类型昆虫-植物对大气CO₂浓度升高的响应机制。
 

英文摘要：      Global    warming accompanied by increased atmospheric CO₂ is the subject of enormous interest from scientists. Evidence of the direct effects of elevated CO₂ on herbivorous insects is weak, and the major influence of CO₂ on insects is through a cascade effect when host plants alter their primary and secondary metabolites. This review focuses on elevated CO₂ as the main factor determining the interaction between plants and herbivorous insects. We here compare the responses of browsing herbivorous insect and phloem sucking insects to elevated CO₂. We also explore the different response mechanisms of different insect feeding guilds to elevated environmental CO₂.
