Neonicotinoid pesticides 'damage brains of bees' http://apocadocs.com/s.pl?1364485218
Commonly used pesticides are damaging honey bee brains, studies suggest.
Scientists have found that two types of chemicals called neonicotinoids and coumaphos are interfering with the insect's ability to learn and remember.
Experiments revealed that exposure was also lowering brain activity, especially when the two pesticides were used in combination....
Dr Christopher Connolly said: "We found neonicotinoids cause an immediate hyper-activation - so an epileptic type activity - this was proceeded by neuronal inactivation, where the brain goes quiet and cannot communicate any more. The same effects occur when we used organophosphates.
"And if we used them together, the effect was additive, so they added to the toxicity: the effect was greater when both were present."
