Interesting comment Indy:"However, Bayer eco-toxicologist David Fischer said the honeybee study used doses of pesticides far higher than those used on crops bees normally pollinate"
Bayer is going to say whatever needs to be said in order to keep their product on the market. As has been pointed out in numerous studies and Bee journals, the studies that Bayer has done to show that neonics are "safe" to bees are following protocols that really don't apply. More specifically, pesticide toxicology protocols done to meet EPA testing requirements are based on 'old-style' pesticide applications (e.g., spraying something ON the plant). Neonics are systemic - they are IN the plant. It's sort of like saying that because a chemical doesn't hurt you if you spill on on yourself, therefore it must be safe to drink.
