Name of scholarship/program
The evolution and ecology of how mutualist bacteria protect their insect hosts from disease
Eligibility and other criteria
The proposed project will use the pea aphid, a model organism for studies in ecology and evolution, to investigate evolution of symbiont-conferred defence. Aphid resistance to parasitoid wasps and fungal pathogens is often reliant on mutualistic symbioses between the aphid and one or more species of intracellular bacteria (secondary symbionts). We are able artificially to manipulate these symbiont infections through antibiotic curing and microinjection, which enables us to separate the influence of aphid genotype and symbiont genotype on the observed resistance phenotype. Work carried out in our lab has shown that four different species of bacteria, representing diverse bacterial groups, are capable of conferring protection against the aphid-specific fungal pathogen Pandora. The DPhil project will investigate the roles of these different bacteria in aphid resistance to fungal pathogens, aiming to link ecological characteristics (natural enemy resistance, and variation in symbiont prevalence between aphid populations) to insect-microbial interactions.
