Randy, nationally, the corn acreage (and associated clothiandin usage) is highly concentrated in northern Iowa, southern Minnesota and northern Illinois: http://i959.photobucket.com/albums/ae78/18R-C/cornmap.jpg My understanding is the corn grown in that area sheds pollen only for a 7-10 day period in July. I am not aware that a "pollen dearth" exists in that region in July that might tend to cause the bees to gather corn pollen. Does anyone even have a video of bees in a corn belt State gathering corn pollen? I searched YouYube and couldn't find any. Bottom line is I am wondering just how bees in the corn belt could be significantly exposed to clothiandin contaminated corn pollen on a landscape scale and over a multi-week period?
