The experts have concluded that there still remain major gaps in our understanding of how pollinator colony-level (for social bees) and population processes may dampen or amplify the lethal or sublethal effects of neonicotinoid exposure and their effects on pollination services; as well as how farmers might change their agronomic practices in response to restrictions on neonicotinoid use and the resulting positive or negative effects on pollinators and pollination.
They added: "While these areas continue to be researched there is still a limited evidence base to guide policymakers on how pollinator populations will be affected by neonicotinoid use or how agriculture will respond to neonicotinoid usage restrictions."
Meanwhile, a second UK Bee Summit, hosted by Friends of the Earth and the National Federation of Women’s Institutes, is due to take place on Monday 9 November.
FOE said: "The summit comes at a time of vital importance for bees and other pollinators. Evidence about the multiple threats to bees continues to mount. If we are to achieve, together, the vision of the National Pollinator Strategy and the plans of the devolved administrations to restore bee and pollinator populations, action must be accelerated, scaled up, and commensurate to the challenges our bees and pollinators face.
