Genetic variation in the effect of a facultative symbiont on host-plant use by pea aphids.

Oecologia - 1 Aug 2007

Ferrari Julia, Scarborough Claire L, Godfray H Charles J

Abstract excerpt

Ecological specialisation on different host plants occurs frequently among phytophagous insects and is normally assumed to have a genetic basis. However, insects often carry microbial symbionts, which may play a role in the evolution of specialisation. The bacterium Regiella insecticola is a facultative symbiont of pea aphids (Acyrthosiphon pisum) where it is found most frequently in aphid clones feeding on...
