Are the Bees Dying off Because They're Too Busy?

All across America, a mysterious disease is wiping out bee colonies. This malady causes all the bees in a hive to seemingly vanish overnight, abandoning their brood in the nursery, as well as their stores of honey and pollen. Other bees and pests, which normally plunder deserted honey, shun these hives. This baffling die-off dealt a financial blow to commercial beekeepers this season and raised fears of environmental and economic disaster. For farmers, no bees means no pollination.

But pollination is happening like mad in Leah Fortin's tiny yard in North Oakland, Calif. Busy little bee bodies cover the clumps of lavender, salvia and roses that line her driveway. More bees work the malaleucas on the parking strip, those trees with shaggy bark that look like giant Q-tips when they're in bloom.

A lot of these bees -- although surely not all -- come from the hive on Fortin's roof. The unobtrusive wooden box, barely 20 inches by 16, and 13 inches high, sits on the tar-and-gravel roof of her stucco bungalow, sheltered by the chimney. Honeybees bustle in and out of the narrow slit along the bottom, delivering bundles of pollen and droplets of nectar, then hurrying out again for more.

"The neighbors call us 'The Little House on the Prairie,'" Fortin said on a recent summer afternoon. "They think I'm a kook."

Fortin, who administers after-school programs, captured this wild swarm in early May, and so far it's thriving. "My book said to take two pieces of cardboard and scoop them into a five-gallon paint can, so that's what I did," she said. "I was scared shitless. I had no idea what I was doing." She covered the can with a net and drove home. "It worked, and there they are."

Fortin put out a small jar of honey to make the new colony feel at home; since then, she's done nothing except peek at them once in a while. "It doesn't matter what you know and what you don't know," she said. "The bees know what they're doing." And what they do is pollinate.

Honeybees aren't native to North America, so indigenous plants don't need them for pollination. If all the honeybees disappeared, we'd still have corn and wheat. But most of the imported fruit and vegetable species commonly thought of as quintessentially Californian -- almonds, grapes, plums, cucumbers, cantaloupe, asparagus -- need the help of bees to wed male pollen to female pistil. Without bees, there would be no apples, no cherries, no tomatoes, no zucchini. Even tofu would be scarcer -- soybeans depend partly on the honeybee for pollination.

Most of these crops are no longer pollinated by wild honeybees. Like many indigenous insects and plants, feral honeybees have been nearly wiped out by pesticides, loss of habitat and parasites like the varroa mite.

Meanwhile, commercial beekeeping has come to resemble other kinds of factory farming. While the bees themselves retain more freedom of movement than almost any other living creature raised by man, a commercial bee lot is more like a cattle feed lot than a wild meadow.

Beehives are crammed close together in rows just a few feet apart; in the wild, a square mile supports at the most three or four hives. A wild colony's diet is diverse, comprising pollen and nectar from myriad plants. To compensate for the lack of forage around bee lots, bees are typically fed high-fructose corn syrup, the same stuff that's contributing to a human health crisis. And just like other agricultural livestock, bees become stressed when you crowd them together. They're more susceptible to diseases and parasites, less able to function naturally.

It's all making some bee scientists wonder: Is the epidemic known as Colony Collapse Disorder real, or are the bees simply being worked to death?

Big beesness

If you want to put bees' value into dollars and cents, just look at California's almond industry. Almonds are the state's second-largest crop, with farmers raking in $2.34 billion in 2005. This year's yield, grown on 615,000 acres, is expected to be a record 1.310 billion pounds, up 18 percent from last year -- despite the dire statistics about Colony Collapse Disorder.
