>I don’t know of any study
Not quite the same thing, but Rothamsted have a three year study into the impact of neonicotinoids on honey bees and bumblebees. They had a stand at Beetradex on Saturday.
I asked: 'what about solitary bees?' Seems they are excluded for the time. But what else are neonicotinoids killing? What about all the other insects that pollinate and together with their larvae provide food for birds?
Best wishes
