honey bee pollen trap
A study of managed bumble bees and honey bees on a blueberry farm finds that most of the pollen they collect comes from other plants, suggesting that supplementing crops with a diversity of nearby plant types makes for healthier bees. A 10-frame superior pollen trap was used for pollen collection, in which bees enter their hive through a screen that knocks off their pollen balls, which gather in a tray, shown here.
