I thought the comments about corn and corn syrup was interesting. 

In the midwest Atrazine is every where, soil, air at times and in the water.  Expectations are for corn 
acreage plantings to be at an all time high this year too with the ethanol boom so the atrzine we be 
abundant. 

Researchers reports tiny amounts can affect frogs, would not tiny amounts be present in corn syrup 
too? 

So its in the honey bees' environment and then perhaps we even feed them more in the fall.

At this point it may be conjecture that Atrazine is a problem for honeybees but one thing is for 
certain proof either way will be slippery or impossible to find anytime soon. 

 ...I think i'll switch to liquid sucrose if I need bee feed.
