Having always been fascinated by nature and the environment, I studied Biology at University College London. Through my studies I became aware that biology and ecology can play a vital role in safeguarding harvests from attack by pests. My undergraduate project was on insect pests of rice and their natural enemies in Malaysia. I completed an M.Sc. in Applied Entomology at Silwood Park, Imperial College London and a Ph.D. in Chemical Ecology at the Natural Resources Institute, University of Greenwich. My PhD thesis was on the role of olfaction in host location by the cotton bollworm, Helicoverpa armigera, with lab studies in the UK and field studies in Israel and Pakistan.

Agriculture interests me because of the vital role it plays in global food security and the opportunities for reducing our environmental footprint through more efficient farming practices. I joined Rothamsted Research, an organisation that pioneered using science to benefit agriculture, as a Research Scientist in 2000. My role was to study agriculturally important insects, their interactions with their host plants and their natural enemies; seeking novel interventions that could improve pest management and reduce dependency on pesticides. For example, I helped to develop improved management of orange wheat blossom midge, Sitodiplosis mosellana, based on resistant wheat varieties and pheromone traps to rationalise insecticide use and evaluated transgenic wheat engineered to release the aphid alarm pheromone. We have had a very successful collaboration with scientists at icipe in Kenya.

I obtained a scientific merit promotion to Senior Research Scientist at Rothamsted in 2007. I gained university teaching experience from guest lectures at several UK and European universities and enjoy teaching. I successfully supervised PhD students in outstanding and highly cited research. In 2012, I became Convenor of the Association of Applied Biologists Biocontrol and IPM group, a visiting Professor at the University of Greenwich and a visiting Lecturer at the University of Nottingham. In 2016, I became editor-in-chief of the journal Physiological Entomology and co-editor of Annals of Applied Biology.

In 2017, was recruited by Keele University to build a new group within our expanding and thriving School of Life Sciences. I am very excited about this new opportunity to strengthen hypothesis driven research, geared towards improving food security by reducing crop losses to pests. I hope to inspire the next generation of researchers to tackle global challenges and push back the boundaries of science.

The newly formed Bruce group at Keele will conduct cutting-edge research on insect-host interactions and test hypotheses to better understand how to sustainably manage pest species and conserve beneficial species.

My scientific achievements include improving understanding of how insects use olfaction to recognise their host plants (Bruce, Wadhams & Woodcock, 2005; Bruce & Pickett 2011). I showed that host odour coding is usually via blends of widely occurring plant volatiles rather than compounds specific to their host and suggested a ‘coincidence detection’ hypothesis in which insects have very high spatio-temporal resolution of olfactory cues and use space and time to put the cues in context. An extreme example of this blend odour coding was when black bean aphid, Aphis fabae, was shown to be repelled by host plant volatiles when they were presented to it individually but repelled when they were presented as a blend (Webster et al 2010).

odour coding by insects

Understanding how plants react to biotic stress such as insect attack. In 2007, I hypothesised that epigenetic mechanisms could explain long-lived plant defence priming phenomena in which a plant can respond more quickly and strongly to subsequent exposure when exposed to a previous stress than a naïve plant (Bruce et al. 2007). This type of plant ‘stress memory’ seemed controversial at the time but in the last decade more evidence to support it has accumulated. My collaborative research with scientists in Kenya has advanced understanding of how maize plants respond to insect egg laying to release volatiles that attract natural enemies of the herbivore. We initially found that certain farmer preferred landraces of maize respond to stemborer insect egg laying: these maize varieties produce different odours, after insect egg laying (Tamiru et al., 2011). The changes in smell repel the pest herbivore (stemborer moths) and attract natural enemies of this devastating pest. The natural enemies (parasitic wasps) use the smells to locate plants colonised by pest and then parasitise their eggs and larvae (immature caterpillars), thus preventing the crops from being damaged. In a larger project, which I obtained funding for, we found this trait also exists in improved maize varieties although it is much rarer than in landraces (Tamiru, Khan and Bruce, 2015).

stemborer eggs

I have been involved in numerous studies with a common theme of biological interactions. Recent developments have included showing that grain aphids can facilitate Fusarium head blight disease in wheat (Drakulic et al. 2017) and that virus infection of tomato plants can make them more attractive to buzz-pollinators (Groen et al. 2016). I have an excellent publication record with over 100 papers in peer-reviewed Journals, including PNAS, Ecology Letters, Nature Climate Change and Trends in Plant Science. I have been invited as a keynote speaker to numerous scientific meetings, for example, the Plant Volatiles Gordon Conference in 2016. I have developed and mentored talent especially in PhD students and postdoc fellows, several of whom have achieved highly cited publications. I am keen on outreach and developed a smartphone App for farmers to report crop protection targets and obtain management recommendations for pests, weeds and diseases.

This is my first academic year at Keele. I will be responsible for lecturing on at least two courses and supervising at least 3 student projects. 

Students may like to know the purpose of my subject area: Ensuring crop health by better managing pests not only safeguards harvests but also reduces the environmental footprint of farming by allowing more efficient crop production. There is fascinating science in understanding the complex biological interactions between insects and other species.
