According to the European Union Food Safety Authority, most uses of neonicotinoids represent a risk to wild bees and honeybees. The report released [Feb. 28] comes out despite strong evidence that shows neonicotinoid pesticides are the least of concern when it comes to saving bees.

Researchers from the Universities of Wageningen, Ghent, and Amsterdam came to a different conclusion when they summarized 15 years of research on the hazards of neonicotinoids to bees for the first time. While many laboratory studies and other studies applying artificial exposure conditions described sublethal and other effects, no adverse effects to bee colonies were ever observed in field studies at field-realistic exposure conditions.

These findings are in line with many large-scale, multifactorial studies that were undertaken in the USA, Austria, Belgium, Canada, France, Germany, and other countries. The studies have shown poor bee health is more often correlated with the presence of the Varroa mites, viruses, and many other factors, but not with the use of insecticides.
