Do bacterial endosymbionts influence vine weevil pest status and control?

Abstract

Many herbivorous pests harbour a community of endosymbiotic bacteria that influence insect fitness, survival and ability to tolerate environmental stress, but the frequency of facultative endosymbionts in O. sulcatus populations, and their impact on insect fitness, is unknown. The project will combine a metagenomics analysis of insect microbial communities with studies of insect behaviour to explore how fitness of the root-feeding pest vine weevil, Otiorhynchus sulcatus, varies in relation to source population and microbial endosymbiont presence. The student will receive training in techniques for metagenomics and functional analysis of insect microbial communities, within the context of understanding the ecology and management of insect pests.
