Fig. 3From: Symbiont interactions with non-native hosts limit the formation of new symbiosesMean lifetime fecundity of aphids feeding on broad bean (V. faba) (a, b) and on native host plants (c, d). Aphids infected with symbionts (dark grey columns) are compared to the same symbiont-free aphid clone (light grey columns). Mean fecundity of aphid clones carrying the L. pedunculatus symbiont strain are presented feeding on broad bean (V. faba) (a) and their native host plant (c). Mean fecundity of aphid clones harboring the M. sativa symbiont strain are also presented for aphids feeding on broad bean (V. faba) (b) and their native host plant (d). Native symbiont-host genotype comparisons are on the left of each panel. Error bars denote standard errorBack to article page
