Fig 3. Mean survival (±S. E. M.), as a measure of Rapid Cold Hardening (RCH) ability, of d 6 Calliphora vicina females either developed on sugar, water and liver (SWL), or sugar and water (SW) only.

RCH was assessed as survival at their respective discriminating temperatures (DTemp—in shaded grey area for comparison) following a 6 d thermal cycle (between 10 and 20°C) at which adults were removed at either 10°C, 15°C or 20°C. * denotes significant differences from DTemp at p<0.05, ** at p<0.01 and *** at p<0.001 (Bonferroni post-hoc). 6 replicates of n = 10 for each data point.
