Re: CCD and Urban Beekeepers
This is one of the problems though and why the causes of CCD are still so vague. Sure, bees dosed with thiamethoxam (another popular neonicotinoid) may be twice as likely to die. But I'd be pretty sure bees dosed with any insecticide will be twice as likely to die.
The latest figures do show reported CCD to have waned a lot in the last 3 years. If it's neonicotinoid, CCD should have increased.
Having said that, the results of certain research are that neonicotinoid exposure does weaken the bees and make them more susceptable to other ailments such as nosema.
44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).
