1. Although bee declines can be attributed to multifarious causes, the use of neonicotinoids is increasingly held responsible for recent honeybee losses.
2. Neonicotinoids show high acute toxicity to honeybees.
3. Chronic exposure of honeybees to sub-lethal doses of neonicotinoids can also result in serious effects, which include a wide range of behavioural disturbances in bees, such as problems with flying and navigation, impaired memory and learning, reduced foraging ability, as well as reduction in breeding success and disease resistance.
4. Recent scientific findings are urging to reassess the bee safety of approved uses of neonicotinoid insecticides at European level. A current review, carried out by the European Food Safety Authority EFSA (on behalf of the European Commission) will give new insights into this issue.
As long as there are uncertainties concerning the effects of neonicotinoids on honey bees, the Precautionary Principle in accordance with the Regulation (EC) No 1107/2009 should be applied when using neonicotinoids.
