Research Interests

Dr Ben Clunie is an applied entomologist with expertise in integrated pest management and agroecology. He has a PhD that explored novel solutions for biological control of wireworm from Swansea University and has developed experience in working with entomopathogenic fungi, biopesticides and plant-insect interactions. His research focuses on finding sustainable solutions for agriculture that reduce conventional pesticide inputs and developing environmentally friendly alternatives for pest management.

Scientific Inspiration

Alfred Russel Wallace – the namesake of my undergraduate department building, his popular writings in the Malay Archipelago painted the Victorian entomologist as an Indiana Jones style adventurer – really highlighting the importance of communication and inspiration for future generations of scientists. Contributing to the ground-breaking theory of natural selection wasn’t so bad either and is one of the great forgotten examples of collaboration.

Project Outline

The control of wireworm (the larval form of the click beetle) is currently problematic for growers across a range of crops with the deregistration of accepted conventional controls2 and a lack of commercially ready biological alternatives3. The biological control of wireworm currently shows most promise with the application of biopesticides created with entomopathogenic fungi (EPF), with several products available for other invertebrate pests. The primary groups identified for pathogenicity towards wireworm occur within Hypocreales; Metarhizium brunneum (Petch), Beauveria bassiana (Balsamo) and Isaria fumosorosea (Wize)5.

Wireworm exhibit particularly robust defences against the physical penetration of EPF hyphae and the action of enzymes for initial infection7. Previous research has demonstrated the efficacy of EPF Metarhizium in controlling wireworm under laboratory conditions8, but application in the field is restricted by the ability to accurately target the larvae and the time taken to kill and spread infection9,10. Additionally, the impact of abiotic factors (e.g., moisture, temperature, pH) can affect both the stability and efficacy of the EPF once applied to the soil6.

As a result, commercial products containing EPF for insect control must ensure that not only do they have a pest specificity but also are stable through multiple infections (for both mass production and in-field persistence) and robust against abiotic variability. As such, it is crucial that species specific strains of EPF are identified, sequenced and screened for pathogenicity, stability and suitability for commercial viability. The UK is currently far behind Europe and other wireworm hotspots in identifying control solutions for the pest in line with a modern IPM perspective. The use of EPF has been shown to be an effective measure utilised with proper consideration for the ecology of pest and pathogen11 but current knowledge of appropriate species and strains for control is either outdated or potentially regionally specific8.

This project aims to utilise a network of field collected wireworm samples to isolate and identify wild strains of entomopathogenic fungi which may fulfil the requirements for an effective control measure. It will combine molecular techniques with more classical methods for identification of pathogens as well as the host pests (often morphologically indistinct). Experiments post sample collection will focus on insect bioassays to quantify the survivability of the key pest species against found strains and compare this against more generalist commercial strains. Glasshouse or semi field studies may be scaled up from this to diagnose stability and variability in success in a more natural setting. The volatile organic compound profiles of the EPFs will be evaluated with the use of gas chromatography mass spectrometry, with the bioactivity of the EPF constituents towards wireworm quantified to help build a profile of the strains and their natural products.
