From: Are aphid parasitoids locally adapted to the prevalence of defensive symbionts in their hosts?
Relationship between the average infectivity of Lysiphlebus fabarum parasitoids from each site on Hamiltonella defensa-protected aphids and the mean frequency of infection with H. defensa across five aphid host species collected at the same sites. The two open symbols represent sites for which only a single parasitoid line could be tested. For other sample sizes please refer to Additional file 2: Table S2
