Application Deadline: 5 January 2018

 

PhD Description:

 

Plutella xylostella (diamondback moth, DBM) is a major pest for Brassica crops that causes £3.5 billion in damage each year. Given issues such as resistance to and environmental impact of insecticides, sustainable approaches to DBM management are urgently needed. The proposed research aims to expose vulnerabilities of DBM in its rhythmic and coordinated interactions with host plants and its inherent attraction to non-host plants expressing toxic metabolites. The outcome of this research might be exploited in new intervention strategies

 

This project is focussed on improving DBM pest management by employing two strategies: (1) Investigate how herbivory is controlled by environmentally entrained daily rhythms in plant metabolism and DBM behaviour to identify both plant and DBM determinants of crop damage and (2) Identify host defense genes from wild rocket, Barbarea vulgaris, that may be useful in harnessing resistance to DBM.

 

Methodology:

 

The model plant Arabidopsis thaliana will be used to study how daily timekeeping affects DBM damage. The impact of daily timekeeping on herbivory and oviposition will be studied by changing the circadian phase relationship between hosts and pests as well as making use of environmental and genetic manipulations of rhythmicity and plant defence pathways. Relevant molecular rhythms will be measured by real-time PCR analysis.

 

Barbarea vulgaris is a potential ‘dead-end trap’ crop for DBM as some of its varieties entice egg laying but prevent further development. Candidate genes responsible for this resistance in Barbarea will be further evaluated in transgenic experiments with Arabidopsis.

 

This multidisciplinary project offers training opportunities in behavioural, molecular, and genetic experiments in both insects and plants as well as data analysis techniques and oral and written presentation and communication skills.
