Rush is over the top...again
Overworked Bees?

Bee colonies have been under stress in recent years as more beekeepers have resorted to crisscrossing the country with 18-wheel trucks full of bees in search of pollination work. These bees may suffer from a diet that includes artificial supplements, concoctions akin to energy drinks and power bars. In several states, suburban sprawl has limited the bees’ natural forage areas. NY Times, 04/23/07
With the recent slew of info on deadly pet food (also fed to chicken) which was a coal product used in animal feed, to the near collapse of the world’s ocean fisheries (farmed fish are in the same bad category as factory-farm chickens and pigs), tainted produce (the spinach scare) there is a good reason to look at how we get and consume our food. This isn’t just something for hippies and ‘do-gooders’ to do. This is imperative if you would like to see the earth as a healthy and remotely sustainable place in the future.
Honeybees Vanish, Leaving Keepers in Peril
NYTimes, February 27, 2007
In 24 states throughout the country, beekeepers have gone through similar shocks as their bees have been disappearing inexplicably at an alarming rate, threatening not only their livelihoods but also the production of numerous crops, including
“I have never seen anything like it,” Mr. Bradshaw, 50, said from an almond orchard here beginning to bloom. “Box after box after box are just empty. There’s nobody home.”
The sudden mysterious losses are highlighting the critical link that honeybees play in the long chain that gets fruit and vegetables to supermarkets and dinner tables across the country.
Beekeepers have fought regional bee crises before, but this is the first national affliction.
Now, in a mystery worthy of Agatha Christie, bees are flying off in search of pollen and nectar and simply never returning to their colonies. And nobody knows why. Researchers say the bees are presumably dying in the fields, perhaps becoming exhausted or simply disoriented and eventually falling victim to the cold.
As researchers scramble to find answers to the syndrome they have decided to call “colony collapse disorder,” growers are becoming openly nervous about the capability of the commercial bee industry to meet the growing demand for bees to pollinate dozens of crops, from almonds to avocados to kiwis.
Along with recent stresses on the bees themselves, as well as on an industry increasingly under consolidation, some fear this disorder may force a breaking point for even large beekeepers.
A Cornell University study has estimated that honeybees annually pollinate more than $14 billion worth of seeds and crops in the
The bee losses are ranging from 30 to 60 percent on the West Coast, with some beekeepers on the East Coast and in
Beekeepers are the nomads of the agriculture world, working in obscurity in their white protective suits and frequently trekking around the country with their insects packed into 18-wheelers, looking for pollination work.
Once the domain of hobbyists with a handful of backyard hives, beekeeping has become increasingly commercial and consolidated. Over the last two decades, the number of beehives, now estimated by the Agriculture Department to be 2.4 million, has dropped by a quarter and the number of beekeepers by half.
Pressure has been building on the bee industry. The costs to maintain hives, also known as colonies, are rising along with the strain on bees of being bred to pollinate rather than just make honey. And beekeepers are losing out to suburban sprawl in their quest for spots where bees can forage for nectar to stay healthy and strong during the pollination season.
“There are less beekeepers, less bees, yet more crops to pollinate,” Mr. Browning said. “While this sounds sweet for the bee business, with so much added loss and expense due to disease, pests and higher equipment costs, profitability is actually falling.”
Some 15 worried beekeepers convened in
They are also studying a group of pesticides that were banned in some European countries to see if they are somehow affecting bees’ innate ability to find their way back home.
It could just be that the bees are stressed out. Bees are being raised to survive a shorter offseason, to be ready to pollinate once the almond bloom begins in February. That has most likely lowered their immunity to viruses.
Mites have also damaged bee colonies, and the insecticides used to try to kill mites are harming the ability of queen bees to spawn as many worker bees. The queens are living half as long as they did just a few years ago.
Researchers are also concerned that the willingness of beekeepers to truck their colonies from coast to coast could be adding to bees’ stress, helping to spread viruses and mites and otherwise accelerating whatever is afflicting them.
Dennis van Engelsdorp, a bee specialist with the state of Pennsylvania who is part of the team studying the bee colony collapses, said the “strong immune suppression” investigators have observed “could be the AIDSof the bee industry,” making bees more susceptible to other diseases that eventually kill them off.
Growers have tried before to do without bees. In past decades, they have used everything from giant blowers to helicopters to mortar shells to try to spread pollen across the plants. More recently researchers have been trying to develop “self-compatible” almond trees that will require fewer bees. One company is even trying to commercialize the blue orchard bee, which is virtually stingless and works at colder temperatures than the honeybee.
Beekeepers have endured two major mite infestations since the 1980s, which felled many hobbyist beekeepers, and three cases of unexplained disappearing disorders as far back as 1894. But those episodes were confined to small areas, Mr. van Engelsdorp said.
Today the industry is in a weaker position to deal with new stresses. A flood of imported honey from
Beekeepers now earn many times more renting their bees out to pollinate crops than in producing honey. Two years ago a lack of bees for the
This year the price for a bee colony is about $135, up from $55 in 2004, said Joe Traynor, a bee broker in
A typical bee colony ranges from 15,000 to 30,000 bees. But beekeepers’ costs are also on the rise. In the past decade, fuel, equipment and even bee boxes have doubled and tripled in price.
The cost to control mites has also risen, along with the price of queen bees, which cost about $15 each, up from $10 three years ago.
To give bees energy while they are pollinating, beekeepers now feed them protein supplements and a liquid mix of sucrose and corn syrup carried in tanker-sized trucks costing $12,000 per load. Over all, Mr. Bradshaw figures, in recent years he has spent $145 a hive annually to keep his bees alive, for a profit of about $11 a hive, not including labor expenses. The last three years his net income has averaged $30,000 a year from his 4,200 bee colonies, he said.
“A couple of farmers have asked me, ‘Why are you doing this?’ ” Mr. Bradshaw said. “I ask myself the same thing. But it is a job I like. It is a lifestyle. I work with my dad every day. And now my son is starting to work with us.”
Almonds fetch the highest prices for bees, but if there aren’t enough bees to go around, some growers may be forced to seek alternatives to bees or change their variety of trees.
“It would be nice to know that we have a dependable source of honey bees,” said Martin Hein, an almond grower based in
To cope with the losses, beekeepers have been scouring elsewhere for bees to fulfill their contracts with growers. Lance Sundberg, a beekeeper from
He is hoping the Aussie bees will help offset the loss of one-third of the 7,600 hives he manages in six states. “The fear is that when we mix the bees the die-offs will continue to occur,” Mr. Sundberg said.
Migratory beekeeping is a lonely life that many compare to truck driving. Mr. Sundberg spends more than half the year driving 20 truckloads of bees around the country. In Terra Bella, an hour south of
Beekeepers must often plead with landowners to allow bees to be placed on their land to forage for nectar. One large citrus grower has pushed for
But the quality of forage might make a difference. Last week Mr. Bradshaw used a forklift to remove some of his bee colonies from a spot across a riverbed from orange groves. Only three of the 64 colonies there have died or disappeared.
“It will probably take me two to three more years to get back up,” he said. “Unless I spend gobs of money I don’t have.”
