Abstract The life history and fitness of Nilaparvata lugens being reared under ambient level (current CO2 concentration), medially elevated (550 µL/L) and highly elevated (750 µL/L) CO2 concentration for long-term generation were compared using two-sex life table instead of traditional age-specific life table. The results showed that significantly longer larval duration and lower fecundity of N. lugens were observed in 750 µL/L relative to 550 µL/L treatment (P < 0.05). Accordingly, 550 µL/L CO2 significantly enhanced population parameters of N. lugens, including significantly higher intrinsic rate of increase (r), finite rate (λ) and net reproductive rate (RO), but not for 750 µL/L CO2. Taken together, N. lugens performs enhanced development rate, fecundity and survival in individual life history and higher potential in population multiplication under 550 µL/L CO2 level, while only indicates the less enhanced development rate and survival without significant increased capacity of population expansion under 750 µL/L CO2 level. These results should facilitate predicting the fitness and potential population damage of N. lugens, which is valuable for the integrated control of N. lugens in the future increasing CO2 concentration.

使用两性生命表评估 Nilaparvata lugens 响应 CO2 升高的适应性和种群预测

摘要 使用两性比较在环境水平（当前 CO2 浓度）、中等升高 (550 µL/L) 和高度升高 (750 µL/L) CO2 浓度下饲养的 Nilaparvata lugens 的生活史和适应性生命表而不是传统的特定年龄生命表。结果表明，相对于 550 µL/L 处理，在 750 µL/L 处理中观察到的褐飞虱幼虫持续时间显着更长，繁殖力更低（P < 0.05）。因此，550 µL/L CO2 显着提高了褐飞虱的种群参数，包括显着更高的内在增长率 (r)、有限速率 (λ) 和净繁殖率 (RO)，但对于 750 µL/L CO2 则不然。综合来看，褐飞虱的发育速度提高，550 µL/L CO2 水平下个体生活史中的繁殖力和存活率和较高的种群增殖潜力，而仅表明在 750 µL/L CO2 水平下，发育率和存活率提高较少，而种群扩张能力没有显着增加。这些结果应该有助于预测 N. lugens 的适应性和潜在的种群损害，这对于未来增加 CO2 浓度的 N. lugens 的综合控制很有价值。
