Greetings,

I regret discounting the work of the "Bulletin of Insectology" as they have obviously published reams of cutting edge material on this and other topics. Their impact may have been minimal, but they have done a lot of homework.

They published papers presented at Proceedings 8th International Symposium of the ICP-BR Bee Protection Group Hazards of Pesticides to Bees, Bologna (Italy) September 4-6, 2002

You can visit their website and read these papers. Fully ten of them are about "The effect of imidacloprid on honey bees", including "Long-term toxicity assessment of imidacloprid to evaluate side effects on honey bees exposed to treated sunflower in Argentina".

Additional papers include six on "Test methodology and studies of effects of pesticides on honey bees". So this topic has been under intense scrutiny for more than ten years.

To read and digest the material is a daunting task, I know, but ten years down the road people like Dennis van Engelsdorp who was first on the scene of CCD, state "We conclude that dietary neonicotinoids cannot be implicated in honey bee declines".
