Proportion of arrested whiteflies (proxy for CI-mortality) generated from crosses involving male wasps exposed to different temperature shocks.

Color of bars denotes temperature treatment (grey = 27°C, red = heat shock at 40°C, blue = cold shock at 4°C). Treatments are also separated by the stage at stage temperature exposure began. R = rescue cross, C(+) female x C(+) male. CI = CI cross, C(-) female x C(+) male. Asterisks denote significant differences compared to respective crosses at 27°C. Numbers represent replicates for each cross. N = 8–10, with the mean offspring per male = 15.3.
