摘要: 综述了CO2浓度升高对植物与昆虫相互关系影响的研究结果。大量研究表明,高浓度CO2对植物生理生化活动有显著的影响,植物营养物质的变化对植食性昆虫亦产生不同程度的影响,高浓度CO2条件对咀嚼式口器昆虫的取食、生长发育和生殖有不同程度的不良影响,昆虫为了获得足够的氮素营养而增加取食强度和时间,从而更易于受到天敌的攻击,这些昆虫的生长率、繁殖和生存率有下降的趋势;而对刺吸韧皮部汁液的昆虫来说,多引起种群数量增加或无显著影响。并对研究中存在的问题进行了分析,提出了今后研究的方向。

Abstract: Advances in rese arch on effects of elevated carbon dioxide on insect-plant interactions were reviewed in this paper.It has been well demonstrated that plants exhibited physiological and biochemical alterations under elevated CO2 conditions,which in turn affect phytophagous insects at different levels.The feeding pattern,growth and development of chewing herbivores were all influenced by elevated CO2,who increased feeding intensity and time for enough nitrogen nutrition,which in turn made them more subjected to their natural enemies and decreased their growth,breeding and survival rates.Most of the sap-sucking insects showed no significant reactions to the elevated CO2,with some increase in population number.Some suggestions for future research were put forward.
