Warnings of an impending "bee apocalypse" became widespread in 2006, after some commercial beekeepers reported the mass disappearance of worker honeybees from a substantial proportion of their hives, leaving behind larva, young bees, queen bees, and supplies of honey. That winter, between 651,000 and 875,000 of the nation's estimated 2.4 million commercial colonies were lost to the phenomenon, dubbed colony collapse disorder (CCD).

Similar mass colony losses have been documented 23 times since 1868. The current outbreak is associated with infestations of invasive varroa mites; with new diseases, including Israeli acute paralysis virus and the gut parasite Nosema; with exposures to some pesticides applied to crops or used to control in-hive parasites; and with poor nutrition stemming from inadequate forage.

Commercial beekeepers across the United States lost 40.7 percent of their honeybee colonies from April 2018 to April 2019, according to the latest annual survey conducted by researchers at the University of Maryland. That loss is a slight increase over the annual average of 38.7 percent, which is roughly double the normal rates prior to the appearance of CCD.

In his August/September 2017 Reason article, "How Capitalism Saved the Bees," Shawn Regan, a research fellow at the Property Environment Research Center in Bozeman, Montana, reported that in spite these CCD losses, the number of commercial colonies in the United States has basically remained steady over the past two and half decades, at around 2.5 million hives:

"Thanks to a robust market for pollination services, [commercial beekeepers] have addressed the increasing mortality rates by rapidly rebuilding their hives, and they have done so with virtually no economic effects passed on to consumers," explained Regan. "It's a remarkable story of adaptation and resilience, and the media has almost entirely ignored it."

Commercial beekeepers criss-cross the country selling their honeybees' pollination services to farmers. Many travel in early spring to pollinate almonds in California, then on to Oregon and Washington for apples, pears, and cherries, and later on to blueberries in Maine. The U.S. Department of Agriculture has suspended publication of its annual cost-of-pollination reports, but in 2016 income from pollination services was reported as $338 million.

To satisfy the demand for pollination services, beekeepers have long developed techniques for rebuilding lost colonies. This is routinely achieved either by splitting and then introducing a new queen to healthy hives or purchasing packaged bees consisting of around 12,000 workers and a queen from breeders.

A new study in the Journal of the Association of Environmental and Resource Economists confirms that beekeepers have readily adapted to the challenges posed by CCD. Among other things, they find that "the CCD-induced increase in pollination fees increased the retail price of a $7-per-pound can of Smokehouse Almonds by approximately 1.2% or 8.4¢."
