Soil Association scientific briefing reveals new data on the impact of neonicotinoids on pollinators:

New data revealed today shows bees can be exposed to more pesticides from contaminated wildflowers than from crops on farms. The research, discussed at a scientific briefing in London on 28 April 2016 organised by the Soil Association, showed a staggering 97% of the neonicotinoids brought back to honeybee hives in pollen could come from wildflowers – not oilseed rape. (1)

The briefing looked at the latest scientific research and its implications for the environment and the future use of neonicotinoid pesticides in the UK. The panel included three leading experts on the impacts of neonicotinoid pesticides on our pollinators – Professor Dave Goulson, Dr Lynn Dicks and Dr Penelope Whitehorn. Peter Campbell from Syngenta responded to the presentations from the three scientists.  

The panel discussed the recently published, first ever assessment of pollinators by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), recent research on population impacts of neonicotinoids, and new research on the risk posed by neonicotinoids and other pesticides in wildflowers and hedgerows.

Professor Dave Goulson revealed new scientific research that found when neonicotinoids are applied to seeds, low concentrations are found in the nectar and pollen of the crop, which are then collected and consumed by bees. But throughout spring and summer, mixtures of neonicotinoids and other pesticides are also found in the pollen and the nectar of wildflowers growing in arable field margins and hedgerow flowers like hawthorn, wild rose, blackberries and honeysuckle at concentrations that are sometimes much higher than those found in the crop.

Dave Goulson said; “Indeed, the large majority (97%) of neonicotinoids brought back in pollen to honey bee hives in arable landscapes was from wildflowers, not crops. Both previous and ongoing field studies have been based on the premise that exposure to neonicotinoids would occur only during the blooming period of flowering crops and that it may be diluted by bees also foraging on untreated wildflowers. Here, we show that exposure is likely to be higher and more prolonged than currently recognised because of widespread contamination of wild plants growing near treated crops.”

One in 10 species of Europe’s wild bees is facing extinction, and neonicotinoid insecticides are increasingly seen as contributing to these declines.  In addition to neonicotinoids, farmers may spray non-organic crops a dozen or more times while they are growing, with anything up to over 20 different chemicals. (2)

Peter Melchett, policy director at the Soil Association said; “This shocking new research shows that the very wildflowers that were designed to protect bees are actually killing them. The scientific panel agreed pesticides in general, and neonicotinoids in particular, are one of the key reasons why bumblebees and other pollinators are in decline. But the dramatic new issue raised at this briefing is that we cannot save bees while we continue any use of neonicotinoids – the current ban should be extended to all crops.

“The routine, regular use of any toxic chemical or drug is now seen as bad practice – and seed coatings like neonicotinoids are just that – used routinely, and long before any problem emerges – this  prophylactic use of pesticides should be stopped.”

To combat bee decline, the Government’s Pollinator Strategy has focused on creating ‘safe havens’ for bees by increasing flower habitats next to fields – yet this research shows these flowers may be laden with dangerous chemicals.

The panel was chaired by Dr Alastair Leake who said: “we need to be as smart in the way we manage the environment as we are in the way we manage our crops.” Meanwhile, Dr Penelope Whitehorn concluded that neonicotinoids do have far reaching impacts on many different species.  Dr Lynn Dicks called for improving regulatory systems globally – some are not as robust as others and pollinators in countries like Africa are facing a rapid decline.

The panel concluded that the current ban on neonicotinoids should be maintained, and that more work needs to be done looking at chronic exposure to neonics – the current regulatory system is flawed and only looks at a limited period of exposure and does not include exposure to chemical cocktails. The panel also called for more large-scale landscape studies.

About the panel

Professor Dave Goulson of Sussex University, a leading expert in the ecology of bees and other insects who has published 200 scientific papers and two books on the subject. Professor Goulson’s latest research, published in December 2015, found that bees are exposed to a toxic cocktail of neonicotinoids and other pesticides in our hedgerows and wildflower margins – a finding potentially with far-reaching implications for our current strategy for the protection of pollinators in the UK.

Dr Lynn Dicks, a Research Fellow funded by the Natural Environment Research Council (NERC), based at the University of Cambridge. Dr Dicks is an expert in the pollinator conservation, and has been involved in numerous projects and consultations to help develop pollinator strategy and policy. Her most recent work has been as the coordinating lead author of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) thematic assessment of pollinators, pollination and food production. The IPBES is the major global scientific organisation set up by the United Nations to assess the state of the world’s ecosystems and biodiversity.

Dr Penelope Whitehorn of Stirling University. Dr Whitehorn is an applied ecologist, and an expert on bumblebees and other pollinating insects. She is currently researching the effects of sublethal doses of neonicotinoids on bumblebees and other pollinators in a variety of settings. Her previous research has examined the effect of the neonicotinoid imidacloprid on bumblebee colony growth and queen production, and the effects of inbreeding and parasitism on bumblebees.

Alastair has a degree in Horticultural Science, specialising in biological crop protection and a PhD in organic, integrated and conventional farming systems. He is the former Deputy Chair of the Expert Committee on Pesticides, an Honorary Fellow of National Institute of Agricultural Botany, a Trustee Director of Rothamsted Research and Chairman of the Royal Agricultural Society’s Awards Panel.
