The effects of two levels of CO2 （ 375 μL/L VS 750μL/L） on the cotton - Aphis gossypii - Lysiphlebia japonica system were studied using OTCs. We evaluated the influence of direct and indirect stress from L. japonica on the fitness response of aphids to changing CO2 for three successive generations. We wished to show whether CO2 levels, generation and L. japonica-stress markedly determined the fecundity, net reproduction, mean generation time and intrinsic rate of increase in cotton aphids, and whether interactions between these variables al...
