Effects of elevated CO2 on the fitness and potential population damage of Helicoverpa armigera based on two-sex life table

Abstract We evaluated the direct effects of three different atmospheric CO2 concentrations (380 ppm, 550 ppm and 750 ppm) on the population parameters of the cotton bollworm, Helicoverpa armigera fed an artificial diet. The life history and fitness of H. armigera were analyzed using an age-stage, tw...
