The Royal Society has published a new review of more than 80 scientific studies on the effect of neonicotinoid pesticides on insect pollinators. But it seems the jury is STILL out.
The science on this subject is both contradictory and controversial with many pieces of respected research now questioned because of who funded them, such as companies that manufacture neonic pesticides. EU countries and many US states have neonic bans, farmers groups try hard to get exemptions or have the bans overturned, while environmental groups are pursuing bans in other countries.
The review concludes that:
The new evidence and evidence syntheses that have been published in the last 18 months (between February 2014 and August 2015) significantly advance our understanding of the effects of neonicotinoids on insect pollinators. Nevertheless, major gaps in our understanding remain, and different policy conclusions can be drawn depending on the weight one accords to important (but not definitive) science findings and the weightings given to the economic and other interests of different stakeholders. The natural science evidence base places constraints on policies that claim to be consistent with the science, but does not specify a single course of action.
