The number of commercial U.S. honeybee colonies declined 8.1 percent to 2.59 million in 2015, according to the U.S. Department of Agricultures first-ever honeybee health survey released Thursday. Beekeepers needed to replace 44 percent of all their hives last year to maintain insects pollinating almonds, apples and other key crops, according to a separate study published May 10 by a group of researchers.
Honeybees pollinate about $15 billion worth of crops annually, according to the USDA.
