Fig. 1. Aphid performance on diets of different sucrose concentration. (A) Lifetime survivorship. (B) Cumulative reproductive output per live aphid. (C) Relative growth rate of 6- to 8-day-old final instar larvae that had been raised from day 2 to day 6 on a diet with 0.5 mol l^–1 sucrose (means ± s.e.m.). Values that are not significantly different (P>0.05) are indicated by the same letter.
