Parasitoid resistance conferred by H. defensa strains in different host backgrounds, measured as the proportion of surviving aphids out of total number stung. a Mean survival in symbiont-free hosts (light grey columns) from two genotypes compared to survival in hosts infected with the L. pedunculatus strain of H. defensa (dark grey columns). b Mean survival in symbiont-free hosts (light grey columns) from two genotypes compared to survival in hosts infected with the M. sativa strain of H. defensa (dark grey columns). Columns on the left of each panel represent comparisons of uninfected hosts to native host-symbiont genotype combinations and columns on the right are comparisons to non-native combinations. Error bars denote standard error
