| are aphid parasitoids locally adapted to the prevalence of defensive symbionts in their hosts? | insect parasitoids are under strong selection to overcome their hosts' defences. in aphids, resistance to parasitoids is largely determined by the presence or absence of protective endosymbionts such as hamiltonella defensa. hence, parasitoids may become locally adapted to the prevalence of this endosymbiont in their host populations. to address this, we collected isofemale lines of the aphid parasitoid lysiphlebus fabarum from 17 sites in switzerland and france, at which we also estimated the f ... | 2016 | 27955622 |
