Mean mummification rate (%) of G1 <i>A. ervi</i> wasps.

<p>This figure represents the mean percentage (±95% CI) of G1 <i>A. ervi</i> wasps forming mummies, whose mothers had been submitted to a heat stress for a duration of either 1 h (white bars) or 48 h (grey bars), at a temperature of 25°C or 28°C (N = 7), compared to progeny of the females that underwent the 20°C control treatment (N = 6). The total number of attacked aphids monitored is written at the base of each bar.
