To assess the effect of elevated CO on the development, fecundity, and population dynamic parameters of , the age-stage, two-sex life table was used to predict the individual fitness and population parameters of three successive generations of in this study. The results show that a significantly longer total pre-adult stage before oviposition (TPOP) was observed in the third generation compared with the first generation of under the 800 μL/L CO treatment. The fecundity is significantly lower in the 800 μL/L CO treatment than that in the 400 μL/L CO treatment in the third generation of , which indicates that elevated CO had a negative effect on the individual fitness parameters of . Additionally, the life expectancy () is significantly lower under the 800 μL/L CO treatment than that under the 400 μL/L CO treatment in the three successive generations. A significantly higher intrinsic rate of increase () and finite rate of increase () were found in the second generation compared with those in the first and third generations of under the 800 μL/L CO treatment. Moreover, significantly lower and were observed under the 800 μL/L CO treatment compared with those under the 400 μL/L and 600 μL/L CO treatments in the first generation of , which indicates that elevated CO has a short-term effect on the population parameters ( and ) of . Our experiment can provide the data for the comprehensive prevention and control of in the future with increasing CO levels.
为评估高浓度二氧化碳（CO）对[昆虫名称]发育、繁殖力及种群动态参数的影响，本研究采用年龄-阶段两性生命表预测了[昆虫名称]连续三代的个体适合度和种群参数。结果表明，在800 μL/L CO处理下，与第一代[昆虫名称]相比，第三代产卵前的总未成熟期（TPOP）显著延长。在第三代[昆虫名称]中，800 μL/L CO处理下的繁殖力显著低于400 μL/L CO处理下的繁殖力，这表明高浓度CO对[昆虫名称]的个体适合度参数有负面影响。此外，在连续三代中，800 μL/L CO处理下的预期寿命（[预期寿命符号]）显著低于400 μL/L CO处理下的预期寿命。在800 μL/L CO处理下，第二代[昆虫名称]的内禀增长率（[内禀增长率符号]）和周限增长率（[周限增长率符号]）显著高于第一代和第三代。此外，在第一代[昆虫名称]中，800 μL/L CO处理下的[参数符号1]和[参数符号2]显著低于400 μL/L和600 μL/L CO处理下的[参数符号1]和[参数符号2]，这表明高浓度CO对[昆虫名称]的种群参数（[参数符号1]和[参数符号2]）有短期影响。我们的实验可为未来随着CO浓度升高对[昆虫名称]进行综合防治提供数据。
