AAB - President
Biological Control and Integrated Pest Management Group

Biological control and intergrated pest management aims to minimise crop damage and control unwanted organisms by using naturally occurring predators, parasites and diseases. With the pressure to reduce pesticide use and increase the sustainability of farming as well as manage harmful non-native species, more producers and land managers are looking towards biocontrol as a means to achieve these goals.


Biocontrol already forms an integral part of many integrated cropping systems but further research and development is needed if its full potential is to be realised and it is to be more widely implemented. Our Biocontrol Group includes specialists from all the main fields of biocontrol research and our goal is to encourage discussion and co-operation among members of this interdisciplinary topic.

Toby Bruce

Toby is a Prof of Insect Chemical Ecology at the School of Life Sciences at Keele University. He has a background in Biology and a PhD in Chemical Ecology. His research focuses on host location in insects, alarm and sex pheromone signals and induced plant defence. He has 50 scientific publications which include high impact journals such as PNAS and Trends in Plant Science. As well as advancing fundamental aspects of insect host location, he devises strategies for utilising semiochemicals for insect pest management at the field level ranging from plant activators that switch on plant defence to pheromone monitoring systems. He has very recently obtained national (BBSRC) funding for two IPM related projects, one on transgenic wheat emitting aphid alarm pheromone (BB/G004781/1) and the other on seed treatments to induce resistance to pests and diseases in tomato (BB/G021791/1). He supports a collaborative project on maize pests with Kenya and has organised an international conference on plant signalling in 2008.

My main areas of interest are: entomopathogens and microbial contro; ecology and physiology of entomopathogenic fungi; biopesticide regulation and governance; and Integrated Pest Management. I’ve worked at Warwick at HRI since 1990. Previous to this, I studied for a bachelor degree in biology at the University of Nottingham, followed by a PhD in mycology at Kings College London.


Rosemary Collier
Rosemary's main interests are modelling interactions between insects and the environment, the host-plant finding behaviour of phytophagous insects and the development of Integrated Pest Management systems for the pests of field vegetable and bulb crops. Rosemary is a research entomologist based at Wellesbourne. She has developed weather-based forecasts of the timing of attack of several pests of field crops; four of which have been used commercially for a number of years. Rosemary is a former convenor of the International Organisation for Biological Control Working Group on Integrated Protection of Field Vegetables. She talks regularly to grower groups and writes topical articles for HDC News and similar publications.


Richard Glass
Richard Glass gained his first degree in Biology at Manchester University, with post graduate studies in Crop protection and Analytical Chemistry. Over 25 years experience with crop protection related research in Europe and Latin America. Specialist areas are pesticide application and safety, occupational and bystander/resident exposure, biopesticide delivery and sustainable production Fluent in Spanish, having worked with coffee leaf rust control in Colombia and extensively with intensive horticulture in Spain.
Roma Gwynn
Roma Gwynn is a biopesticide specialist working as an independent consultant, with over around 30 years experience in crop protection and biological control. She has an MSc in Technology for Crop Protection and a PhD in Insect Pathology both from Reading University, UK and she has worked for research organisations and biopesticide manufacturers. Her expertise is in facilitating the process of getting biopesticide products onto the market by streamlining biodiscovery, product development, registration and marketing. Her recent work in Europe, US and Kenya has been in developing and registering new biopesticide products and working to bridge the technical and commercial gaps between the diverse players (academia, policy makers, manufacturers, regulators and growers) involved in biopesticides.


Rob Jacobson
Rob Jacobson has been involved with biological pest control in glasshouse crops for over 20 years. He has previous experience as an extension worker for the UK government, Technical Manager for a biocontrol producer / supplier, and as a Research Leader with the UK’s largest horticultural research organisation. Rob specialises in the implementation of IPM programmes and has focused on strengthening weak links in existing IPM programmes for high input crops, such as cucumber, tomato and pepper, and developing completely new IPM programmes for lower input crops, such as leafy salads and bedding plants. He now operates as an independent consultant and his client’s include the UK’s largest tomato producer and Europe’s largest organic tomato producer. Rob represents both the British Tomato and Cucumber Growers’ Associations, and is also an active member of the International Organisation for Biological and Integrated Control (IOBC) and the International Biocontrol Manufacturers Association (IBMA). He is a Fellow of the Royal Entomological Society.

Phil Morley

Phil Morley is a graduate of the University of Leeds where he completed his PhD in Plant Physiology and Nutrition in the 1990’s. Since then he has worked in the fresh produce glasshouse industry for almost 20 years. His work has concentrated on practical approaches to organic and pesticide free production in large scale commercial Tomatoes crops in the UK and mainland Europe. Phil is now the Technical Director of the British Tomato Growers’ Association and continues to work on a range of HDC funded applied research projects in glasshouse production which range from Pathology and Entomology through to soil biology, plant nutrition and physiology…

Dick Shaw

Dick Shaw has worked in the biocontrol field with CABI since 1993 where he specialises in classical biological control of weeds using insect and fungal natural enemies from the area of origin of exotic invasive plant specices. Currently he is managing a programme against Japanese knotweed, Fallopia japonica which if successful would result in the first intentional release of a classical biological control agent against a weed in Europe ( His main interest is in phytophagous arthropods and their host specificity as well as general biogeography and legislation. He has been a member of the biocontrol working group since 2003, and is an “AAB Ambassador”

His work has taken him to farms and nurseries in various European countries, and further afield to USA, Japan, and Africa, working in a range  of largely protected crops.  He has been an active member of the IOBC ‘Integrated control in protected crops’ working group since 1990. Phil was a past chairman of IBMA UK.

Keith Walters
Keith is an entomologist at Imperial College London whose research interests are organised under two well established and closely interrelated programmes of collaborative multidisciplinary work. The first focuses on the biology of insects and their interactions with the environment, and supports the development of sustainable IPM strategies (utilising conventional pesticides, biological agents and physical control methods) for use in agriculture and horticulture. In addition to yielding new insect management methods and IPM systems that have been adopted by industry, the research has also contributed to the mitigation of potential environmental damage resulting from chemical pollutants through the establishment of ecotoxicological hazards caused by, and reduced reliance on, xenobiotic inputs to the agri-environment. The second is focused on work at the science/policy interface, addressing the biology, impact assessment and policy response to quarantine pests and diseases introduced to the UK on the global trade in plants and plant products and, if they establish in the UK, the use of IPM techniques to contain and eradicate outbreak populations.
Xiangming Xu
I am a plant disease epidemiologist, and conduct research into epidemiology and management of diseases on various crops, primarily in top and soft fruit. In addition, I have also continuously engaged in theoretical studies of the spatio-temporal dynamics of plant disease epidemics. My current interest in biocontrol focuses on development of application strategies of commercial BCAs for effective control of plant diseases
