Mean developmental time (days) of G1 <i>A. ervi</i> progeny.

<p>This figure represents the mean developmental time (± SEM) of G1 <i>A. ervi</i> wasps 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, compared to progeny of the females that underwent the 20°C control treatment. Since the factor “sex” had no significant effect, data from males and females were pooled (cf. text for details). The number of individuals is written at the base of each bar.
