(A) Significant temperature (F1,145 = 32.63, P<0.001) and parasitoid addition (F1,145 = 9.56, P<0.01) effects on larval developmental rates (mean number of days until pupation−1± SE) and interactions between temperature and parasitoid addition (F1,145 = 7.41, P<0.01) and temperature and CO2 (F1,145 = 5.58, P<0.05). (B) Significant temperature (F1,196 = 4.48, P<0.05) and CO2 effects (F1,196 = 7.85, P<0.01) on pupal mass (mean ± SE) and interactions between temperature and parasitoid presence (F1,196 = 13.51, P<0.001) and CO2 and parasitoid presence (F1,196 = 6.22, P<0.05). (C) Significant temperature effect (F1,195 = 7.83, P<0.01) on survival (mean ±1 SE) and interaction between temperature and parasitoid presence (F1,195 = 5.187, P<0.05).
