Bees at these hives near a corn field in Cherokee, Iowa, must pass through a yellow plastic trap that scrapes off a bit of pollen. Researchers are studying whether insecticide-coated seeds could be harming the bee population.
Nathan Anderson stops his red pick-up truck alongside a cornfield on his farm near Cherokee, Iowa. The young farmer pulls on a heavy brown hoodie, thick, long, sturdy gloves and a beekeeper’s hat with a screened veil. He approaches a pair of hives sitting on the edge of a field recently planted with corn and adjusts a yellow plastic flap that traps some of the pollen the bees bring back to their hive.
