Effects of Elevated CO on the Fitness of Three Successive Generations of .

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.
