Stevenson is a Professor of Plant Chemistry at the Natural Resources Institute in the University of Greenwich (UK) where he leads Chemical Ecology research. He holds a dual position as an NERC Merit researcher and Head of Biological Chemistry and In Vitro research at the Royal Botanic Gardens, Kew (UK). Phil’s research has focussed on the biological and ecological functions of plant chemicals and understanding how these compounds can be used in support of sustainable agriculture. His work includes research on pollen and nectar chemistry to determine their role in pollinator behaviour and health and behavioural ecology, natural pest resistance in crops to identify breeding traits and the optimisation of pesticidal plants (botanical insecticides) as benign and affordable alternatives to synthetic insecticides. Phil’s research is or has been funded by UK Research and Innovation (BBSRC), the European Union, Darwin Initiative, USDA and NSF (USA) and the Pewter Sowerby Foundation. His research is published in over 100 international journal articles, including recent papers in Science, Current Biology, Journal of Ecology, Ecological Monographs and Frontiers in Ecology and the Environment. His work has been cited more than 5000 times. His international scientific role is represented through positions on the Editorial Boards of journals including Subject Editor at the Bulletin of Entomological Research, Regional Editor of Biopesticides International and the Editorial boards of Crop Protection, Industrial Crops and Products, Plants (MDPI) and Plants, People, Planet. Phil also advises the UK’s Department for Environment Food and Rural Affairs. He is a Fellow of the Royal Entomological Society and Member of the British Ecological Society and International Society of Chemical Ecology. Steven R. Belmain is a Professor of Ecology at the Natural Resources Institute in the University of Greenwich (UK) where he leads the institute’s research on small mammals and wildlife management. Steve’s research in the field of applied ecology has specialized in the sustainable management of vertebrates and invertebrates as crop pests and disease vectors affecting people living in rural and urban communities, improving the management of natural resources and advancing the livelihoods of the poor. His work on the optimizing the use of pesticidal plants in sub-Saharan Africa stretches back more than 20 years investigating their use in post-harvest insect pest management, their application to a variety of field crops targeting a range of arthropod pests and their integration in to agro-ecologically sustainable production systems. Further research interests include ecosystem services, ecological pest management, agroecology and ecological engineering, entomology, chemical ecology, eco-epidemiology of zoonoses, animal behaviour and small mammal ecology. As principal investigator Steve has led more than 15 multidisciplinary research projects collaborating with institutions in more than 50 countries across Europe, Africa and Asia with funding from the EU and European governments, UN agencies, the World Bank and charitable foundations. He is Associate Editor for the journal Wildlife Research, Fellow of the Royal Entomology Society, Fellow of the Higher Education Academy, Coordinating member of the International Society of Zoological Sciences, Committee member of the World Health Organization’s Global Leptospirosis Environmental Action Network, Member of the British Ecology Society, and author of over 100 publications in peer- reviewed journals, books and book chapters. vii Murray B. Isman was Professor of Entomology and Toxicology at the University of British Columbia, Vancouver, and former Dean of the Faculty of Land and Food Systems. He performed extensive research for over 35 years in the areas of insect toxicology and behavior, with particular emphasis on the discovery and development of botanical insecticides. Others areas of research included insect-plant chemical interactions, metabolism of plant toxins by insects, habituation to antifeedants and insect memory, and non-target effects on pollinators and fish. He has authored over 200 refereed publications (cited >20,000 times according to Google Scholar). Collaborative research with industry has culminated in the commercialization of botanical insecticides partly developed in his
