I have worked occasionally with a local bio-pesticide test Company here in
the UK.  They are staffed exclusively  with really well qualified people,
very knowledgeable about pesticides, test methodologies, regulations and
regulators, the literature on pesticides and about a wide range of insects
in general.  HOWEVER individually and collectively they knew very little
about beekeeping practicalities.

I wonder if a similar issue may be acting among the authors and institutes
of this CEH paper?  That might explain why they have not picked up that in
many cases they were using very small colonies, unrealistic of colonies
that will be placed to work on farmed crops.
