Lu finds a vicious cycle: not only do neonicotinoids wind up in the whole part of the plant (pollen) but he finds that they show up in end products like high fructose corn syrup which is fed back to bees through unsuspecting beekeepers.

It is that last possible cause [pesticides] that stands out to Harvard School of Public Health’s (HSPH) Chengsheng (Alex) Lu, an associate professor of environmental exposure biology, who believes that the potential human health implications of colony collapse disorder extend beyond the drop in pollination — though that is worrisome enough — to the impact on humans of long exposure to low-level poisons like neonicotinoid pesticides, which have been suspected in the bee disorder.

One particularly disturbing aspect of the work, which Lu described during a lunchtime “Hot Topics” talk on Aug. 12 at HSPH’s Kresge Building, is that the bees that abandoned the hive during the collapse weren’t the individuals that ate the sugar water laced with neonicotinoids. During summer’s period of high activity, bees live just 35 days, so the colony that collapsed contained the next generation of bees, indicating that the effect may have been passed on between generations.
Pretty interesting stuff! I've seen other studies suggesting environmental effects seem to persist after multiple generations. Could that lifetime of Soda (flavored HFCS water) consumption cause some unsuspected results in 2-3 more generations?
