Fig. 2: Susceptibility to natural enemies, by infection status and by individual aphid line (± standard error).

a-b Mean percentage of aphids mummified when exposed to a female parasitoid wasp. An average of 4.4 (range of 3–6) replicates were carried out for each aphid line; (c-d) mean percentage of aphids susceptible to the fungal pathogen Pandora neoaphidis, taken as those forming cadavers after exposure to fungal spores. Repeated an average of 5.8 (range of 4–9) times for each aphid line. 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 susceptible to natural enemy), note that while there is substantial variation between lines, for some lines there are also relatively large standard errors.
