Fig. 3: Fecundity measures and survival after heat shock, by infection status and by individual aphid line (± standard error).

a-b Lifetime fecundity on original host plant Medicago sativa, N = 6 for all lines; (c-d) lifetime fecundity on laboratory host plant Vicia faba; (e-f) fecundity after heat shock; and (g-h) survival after heat shock. Seven to eleven replicates (mean 8.3) were conducted for each aphid line and heat treatment. 00 = uninfected aphid line; H = Hamiltonella defensa; F = Fukatsuia symbiotica; HF = co-infection. For tables of individual lines, shade of colour is relative to value in cell (darker = more fecund, or higher survival rate), note that while there is substantial variation between lines, for some lines there are also relatively large standard errors.
