4D X-ray imaging of herbivore foraging behaviour in soil

Wireworms are an economically important group of root herbivores that have a negative impact on the successful establishment of agricultural crops. They tend to prefer cereal crops such as wheat, barley and maize but can also cause damage to the seeds and developing root systems of potatoes, oil seed rape and pulses. Wireworms are the larval form of click beetles (Coleoptera: Elateridae) which have a life cycle of 1-3 years and display a very high resistance to adverse environmental conditions. However the behaviour of wireworms in soil is unpredictable, therefore detail concerning their in situ numbers and their global geographical location is limited. Most recent reports suggest that their impact on crop yields appears to be becoming an increasing problem.

To develop appropriate and effective control strategies information on their spatio-temporal foraging and feeding activities in response to agrochemical applications is urgently needed. The ability to directly image both the behaviour and effectiveness of cidal compounds against soil pests in situ would be a major technological advancement. Micro-scale X-ray Computed Tomography (µCT) has been demonstrated as an effective tool to image undisturbed root-soil interactions rapidly, at high resolutions in 3-D over time. Building on previous research conducted at the University of Nottingham’s world leading Hounsfield Facility (nottingham.ac.uk/microct), this exciting new research project will seek to gain an increased understanding of wireworm behaviour and ecology in soil through the application of state-of the art X-ray imaging including 3-D visualisation and analysis. The research programme is supported by the project sponsors, Syngenta, who will provide expertise in pest behaviour and ecosystem modelling.

Full training will be provided for the PhD student for them to gain key skills across a wide range of interdisciplinary areas to be employed in this project including in root biology, plant-soil interactions, soil science, CT imaging and modelling. The student will be fully trained in the processes and procedures of X-ray image analysis, in addition to spending time with Syngenta as part of a placement opportunity. They will also be able to avail of the generic training courses offered by the University Graduate School. The research undertaken by the student in this project will be novel, world leading and will have strategic importance for a significant global challenge.
