What Was Behind the Honey Bee Wipeout?

By Gina Covina, Terrain. Posted October 16, 2007.


Everyone has a theory why the honeybees started dying off. Try malnutrition.

On Alan Wilson's table at the Oakland Farmers' Market, row after row of glass honey jars catch the early morning sun that angles down Ninth Street. Some of the honey gleams a reddish brown, some a paler amber, depending on the particular mix of flower species the bees foraged. All of it was produced by Wilson's colonies, which number a third of what he had last fall, before the infamous bee die-off that afflicted growers around the world. "I'd better get the honey while I can," one customer remarks.

The flurry of media attention given this winter's bee losses, now labeled "colony collapse disorder," has updated the world of bees for a heretofore-clueless public. Our image of honeybees is a lot like our bucolic images of farm animals -- and just as far from the brutal truth of today's corporate agriculture. We picture fields of clover, blossoming orchards, the wildflowers beneath the trees, filled with happy bees industriously gathering nectar and pollen to take back to the hive. As the bees gather pollen, they transfer it from plant to plant, thus assuring cross-pollination.

Fewer people can picture what happens at the hive, where the bees feed the protein-rich pollen to their developing brood. The adults live on honey they make from collected nectar -- sipped from the throats of flowers into the bees' honey stomachs, disgorged at the hive into the hexagonal wax combs made by the bees, fanned by bee wings to evaporate excess moisture until it reaches the perfect syrupy consistency, and then sealed with a wax cap to keep it clean and ready to sustain the colony over the winter. In order to do all this, bees rely on a diverse range of flowers blooming over a wide stretch of the year.

The honeybee (Apis mellifera) is a European native, one of very few bee species in the world to store honey in bulk and live fulltime in large colonies (30,000 to 100,000 individuals). It is the only bee with a long history of intensive management by people. For almost all of this time, and continuing today in many parts of the world, the rosy picture of bee life painted above is largely accurate. But when beekeeping meets industrial agriculture, the result is very different. Colony collapse disorder may have many contributing causes, but it comes down to bees hitting the biological limits of our agricultural system. It's not so much a bee crisis as a pollination crisis. And we may end up calling it agricultural collapse disorder.

It's a rare beekeeper in the United States who can survive by selling honey. The trade loophole that has flooded this country with low-cost Chinese honey for the past ten years guaranteed that (fortunately for beekeepers, that hole has just been plugged by new federal tariff regulations). The only income remaining has been in pollination services. Alan Wilson's bees are rented out for almond pollination starting in February. After that they go south to the orange groves, then all the way to North Dakota where they make clover honey. Wilson's Central Valley location near Merced has little to offer bees over the dry summer months except roadside star thistle and the brief flowering of cantaloupes in August. Nearby agricultural chemicals are a concern, especially the defoliant used on cotton before harvest. Just the drift from the defoliant has taken the paint off Wilson's hives. Still, this year he plans to keep his bees closer to home where he can manage them more intensively and try to increase their numbers.

Every commercial beekeeper has different arrange-ments, but each involves long-distance trucking and the California almond crop. Almonds are entirely dependent on the seasonal importation of honeybees. Growers can't get crop insurance coverage unless they have at least two bee colonies per acre at almond blossom time; some growers use up to five colonies per acre for heavier yields. Over 800,000 Central Valley acres are planted in almond trees. As beekeeper Randy Oliver says, it is "monoculture at its absolute worst -- they don't allow one species of weed to grow": mile after mile of bare soil and almond trees. No native pollinators can survive on this wasted landscape to ease the honeybees' burden, and nothing lives to sustain bees before or after the almond bloom.

Truckloads of bees begin to arrive as early as November from all over the nation -- it takes virtually all of this country's commercially operated pollination colonies to cover California's almonds. While the bees roll down the highways, hive entrances boarded up, or wait in Central Valley bee yards for the trees to bloom, they're fed a mixture of high fructose corn syrup meant to replace nectar, along with soy protein meant to replace pollen. (Some beekeepers, Wilson among them, have switched to beet syrup as a safer though more expensive alternative.) Oliver sums up the patent absurdity: "When bugs from the east coast have to be trucked to California to pollinate an exotic tree because California has no bugs, it's a pretty whacked-out agricultural system."

Oliver's 500 bee colonies -- he was lucky, with losses under ten percent -- follow a relatively short migratory truck route that takes them from Central Valley almonds to Sierra foothill wildflowers to Nevada alfalfa. He attributes his success to fewer and shorter moves, reliance on pasture forage for much of the year, and avoidance of artificial feeding. "Some of these guys move their bees a dozen times a year," he says. Popular pollination routes include apples and blueberries, which rely on honeybees for 90 percent of their pollination, peaches (50 percent), and oranges (30 percent). Farmers won't bother planting squash or melons if they can't get beehives in place by bloom time. One-third of all US crops depend on honeybee pollination.
