My research focuses on ecological and evolutionary aspects of plant-herbivore-natural enemy interactions. I am particularly interested in the evolution of specialisation and ecological speciation in these systems. Many insects are infected with bacterial symbionts which can have strong ecological effects on their hosts. They can for example increase the resistance of insects to natural enemies such as pathogenic fungi. I am investigating how the symbionts affect their hosts’ ecology. I am particularly interested in how multiple partners in these systems interact and co-evolve. Most of my current work uses the pea aphid, Acyrthosiphon pisum, as a model system. Discoveries We have shown that the pea aphid is a complex of host-adapted populations that show a gradient of differentiation between populations, both in their host use and genetically. These host specialists also differ in which bacterial symbionts they carry, suggesting that the bacteria help the aphid to feed on certain plants.
