I would add to the statement, <<orchards are not and have never been a good place to keep bees year round.>>, that in my grandfather's time orchards were and always had been a good place to keep bees, migratory beekeeping was unknown in the UK at that time, orchards were never sprayed, and fruit was sufficient. 
As for the now largely discredited DEFRA report, it was part of the British Government's campaign to influence the EU's decision on neonicotinoids, as was the ludicrously biased video made by Defra's Chief Scientific Adviser, Professor Ian Boyd, at about the same time, but all this is irrelevant.

The point I was making and the position of UNAF is as follows:
The EU have a partial ban on 3 neonicotinoids. This moratorium is designed to test the effects on pollinating insects.
If, contiguously,  other neonicotinoids are being sprayed on fruit trees in blossom the conclusions drawn from the experiment cannot be valid.   
It is not at all complicated
