I believe the Harvard Study lost credibility mainly because the high doses administered was not field realistic.
This one seems to be the same. (I have read it, a couple of time.) Bees will go for an easy meal, and giving them feeders full of syrup laced with high doses of insecticide is not the same thing as bees foraging, taking nectar and pollen from flowers and collecting water from dew, pig urine or whatever else happens to suit them.
I'll stand by what I've said before - if UK bees are dying and colonies are collapsing because of what's being put on Oil Seed Rape seeds then why are beekeepers, both hobby and commercial, still taking their colonies to fields of the stuff?
I saw, this year, one apiary with hives inches away from a barbed wire fence, which was in turn inches away from rape plants. The very experienced beekeeper didn't seem to be either a fool or a bee murderer. He was happy, his bees were happy and actually gave him a good honey crop.
