[Effects of elevated atmospheric CO2 on plant, herbivorous insect, and its natural enemy: a review].
Since the industrial revolution, the huge consumption of fossil fuels and unduly destruction of natural habitats by human activities have led to the ever-increasing concentration of atmospheric CO2. To study the adaptation mechanisms of plant, herbivorous insect, and its natural enemy 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 related research methods, the variation patterns of host plant primary and secondary metabolites induced by elevated atmospheric 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.
