Join a research initiative aimed at tackling one of agriculture’s most pressing challenges: controlling the Cabbage Stem Flea Beetle (CSFB), Psylliodes chrysocephala. This economically significant pest has devastated oil seed rape and vegetable crops, leading to over £120 million in annual yield losses and severely reduced planting areas.
This PhD project focuses on advancing the CSFB microbiome, particularly endosymbionts, to explore innovative crop protection strategies. Recent research suggests that the microbiome influences critical physiological functions in agricultural pests, including:
Resistance to insecticides.
Adaptation to environmental stresses.
Host plant preferences.
Mating cycles and survival on nutrient-poor diets.
Using advanced molecular biology, genomics, chemical ecology, and bioinformatics, you will characterize the CSFB microbiome and explore its potential for developing targeted, microbiome-based pest control methods.
Key Objectives
Characterization of the Microbiome:
Use 16S/18S rRNA and ITS nanopore sequencing to identify microbiome composition and abundance across all CSFB life stages.
Isolate and characterize culturable microbiome members using microbiological techniques.
Understanding Ecological Adaptation:
Assess the microbiome’s role in host plant preferences, fecundity, insecticide resistance, and phenotypic adaptation through in vivo and in vitro bioassays.
Microbiome Manipulation:
Explore the feasibility of manipulating the microbiome using commercial antimicrobial compounds and natural products with known antimicrobial activity.
