Blueberries and a Bumblebee (IMAGE) University of Vermont Caption New research shows wild bees are essential for producing larger and better blueberry yields -- with plumper, faster-ripening berries. The study is the first to show that wild bees improve not only blueberry quantities, but also size and other quality factors. Their benefits include: greater berry size (12 percent), quantity (12 percent), size consistency (11 percent), and earlier harvests -- by two and a half days. Credit No credit required.
