U.S. cherries, watermelons and some other summertime favorites may depend on wild bees more than previously thought.
Many farms in the United States use managed honeybees to pollinate crops and increase yields, sometimes trucking beehives from farm to farm. Now an analysis of seven crops across North America shows that wild bees can play a role in crop pollination too, even on conventional farms abuzz with managed honeybees.“To me, the big surprise was that we found so many wild bees even in intense production areas where much of the produce in the USA is grown,” says coauthor Rachael Winfree, a pollination ecologist at Rutgers University in New Brunswick, N.J.
That means threats to wild bees could shave profits even when farms stock honeybees, the researchers report July 29 inĀ Proceedings of the Royal Society B. Both honeybees (Apis mellifera), which aren’t native to the United States, and wild pollinators such as bumblebees (BombusĀ spp.).
