摘要大气CO2浓度的升高是未来气候变化中不争的事实，可以预测，它将对农作物及其害虫产生影响。对斜纹夜蛾（Spodoptera litura（F.）（鳞翅目：夜蛾科）饲养的抗性（cv。Lamar）和易感（cv.从2013年到2015年，在开顶室中检测了在高浓度（732.1 ± 9.99 μl/L）和环境（373.6 ± 9.21 μl/L）CO2下生长的JLNMH）大豆。CO2浓度升高促进了两个大豆品种地上部和地下部生物量的积累，提高了根冠比，提高了Lamar的籽粒产量。此外，CO2浓度升高还显著降低了两个大豆品种的幼虫和蛹的体重，延长了幼虫和蛹的寿命，增加了取食量和排泄量。高浓度CO2胁迫下，抗、感大豆品种叶片氮含量显著降低，叶片糖含量和C/N比值显著升高，对S.随着叶片糖含量和C/N比的增加，抗病大豆的叶片糖含量和C/N比均大于感病大豆。在CO2浓度升高的条件下，取食抗性大豆的幼虫的摄食量增幅小于50%，且取食抗性大豆的幼虫寿命比取食敏感大豆的幼虫寿命延长更明显。推测未来大气CO2浓度升高的气候变化可能会导致大豆产量增加和S.抗虫大豆能提高鳞翅目害虫斜纹夜蛾的抗性。斜纹。
Abstract Atmospheric CO2 level arising is an indisputable fact in the future climate change, as predicted, it could influence crops and their herbivorous insect pests. The growth and development, reproduction, and consumption of Spodoptera litura (F.) (Lepidoptera: Noctuidae) fed on resistant (cv. Lamar) and susceptible (cv. JLNMH) soybean grown under elevated (732.1 ± 9.99 μl/liter) and ambient (373.6 ± 9.21 μl/liter) CO2 were examined in open-top chambers from 2013 to 2015. Elevated CO2 promoted the above- and belowground-biomass accumulation and increased the root/ shoot ratio of two soybean cultivars, and increased the seeds' yield for Lamar. Moreover, elevated CO2 significantly reduced the larval and pupal weight, prolonged the larval and pupal life span, and increased the feeding amount and excretion amount of two soybean cultivars. Significantly lower foliar nitrogen content and higher foliar sugar content and C/N ratio were observed in the sampled foliage of resistant and susceptible soybean cultivars grown under elevated CO2, which brought negative effects on the growth of S. litura, with the increment of foliar sugar content and C/N ratio were greater in the resistant soybean in contrast to the susceptible soybean. Furthermore, the increment of larval consumption was less than 50%, and the larval life span was prolonged more obvious of the larvae fed on resistant soybean compared with susceptible soybean under elevated CO2. It speculated that the future climatic change of atmospheric CO2 level arising would likely cause the increase of the soybean yield and the intake of S. litura, but the resistant soybean would improve the resistance of the target Lepidoptera pest, S. litura.
