Beekeepers expect about fifteen percent of their bees to die every winter. But for the past few winters they’ve seen die-offs of thirty percent or more. Mark Brush reports on a new survey that’s keeping track of honeybee losses:

This is the fourth year in a row that beekeepers have see die-offs this high. The survey was done by the USDA and the Apiary Inspectors of America.

Dennis VanEngelsdorp was one of the researchers who conducted the survey. He says the rates of honeybee die-offs threaten the beekeeping business – and that’s important because honeybees pollinate about a third of the foods we eat:

“If we want to produce fruits and vegetables in this country, we need to have honeybees and we need a pollination force. And without those, we won’t be able to produce those in this country. So we’re not going to starve, but certainly the variety in our diet will change.”

Most of the beekeepers blamed the latest deaths on bad weather in the fall and winter. VanEngelsdorp says you can add to that habitat destruction that hurts the bees’ food supplies; invasive mites that spread disease – and the still unexplained problem of Colony Collapse Disorder.

Africanized Honeybees – also known
as killer bees – are moving farther
north. The hybridized bees escaped
from a lab in Brazil in the 1950s.
Mark Brush reports:

These bees have established themselves in a number of states throughout the southern U.S. They spread naturally and they are spread through trade. The bees can hide out in shipping containers. One swarm was found inside the engine compartment of a new car.

Now, despite the nick name “killer bee” – experts say, yes they’ll defend their nest with more gusto – but the killer bee name is just hype.

Gloria DeGrandi-Hoffman is a bee expert with the USDA. She says it’s likely that the bees will keep spreading – but beekeeping is an important line of defense against Africanized honeybees.

“You know, beekeepers, whether they’re small or large, are really the buffer between African bees and the public, because they keep pure European bees.”

DeGrandi-Hoffman says – Africanized or not – bees are still a critical part of our food system because they pollinate so many of our food crops.

Beekeeping is a growing hobby – there
are even a couple of hives on the White
House lawn. And beekeeping is even getting
popular in America’s largest, most urban
city – New York. The only problem is,
beekeeping is actually illegal in New York.
Samara Freemark went to find
out why some New Yorkers are doing it anyway:

When I first got in touch with the Gotham City Honey Co-op and told them I wanted to do a story on beekeeping in New York, they were a little nervous about talking with me. They were worried about a New York City health code that makes urban beekeeping illegal. The city’s worried about people getting stung. The Honey Co-op didn’t want to blow anyone’s cover, but eventually they did hook me up with John Howe.

Howe keeps bees on the roof of his Brooklyn townhouse – which means every day – several times a day, actually – he climbs four flights of stairs and one shaky ladder to get up to his hives.

“I gotta go up the ladder. I’m getting tired of it.”

(sound of roof opening)

“Turned out to be a nice day.”

Howe keeps two hives. He says there could be up to 150,000 bees in them.

“You can see them all going in and out. Lot of bees, yeah.”

Honey bees can fly up to three miles from their hives, looking for flowers to pollinate. Howe’s bees probably buzz by thousands of his neighbors every day. I asked him if anyone ever complained about them or called authorities to turn him in for illegal beekeeping. Howe said his neighbors are actually pretty cool with the bees.

“I give them free honey, so that helps. People just raise their eyebrow or shrug and say, ‘that’s neat.’ They call me bee man. I walk down the street, they say, ‘hey bee man, you got any honey?’”

Across town, Roger Repahl raises honeybees in the garden of a church in the South Bronx. He started beekeeping ten years ago, when local gardeners noticed that their vegetables weren’t getting pollinated.

“The community gardeners were complaining that they were getting a lot of flowers but very little fruit. So Greenthumb – that’s the community gardening wing of the parks department – Greenthumb said that’s because you don’t have enough pollinators in the South Bronx.”

So Repahl trucked some hives down from Vermont, and he says the bees pretty much solved the neighborhood’s pollination problem.

Now, this is the kind of story that gets beekeepers like John Howe pretty steamed up about New York’s anti-beekeeping laws. Like a lot of cities, New York is doing just about everything it can to encourage community gardening. But to grow your own food, you need insects to pollinate your plants. John Howe says banning honeybees is like banning local food.

“The best reason for making bees legal is that they pollinate so many plants. The more bees that we can raise and keep, the more chance we have of having food.”

It’s not quite that clear cut. At least, that’s what James Danoff Burg says. He studies insects at Columbia University. He says there are native bugs that do plenty of pollinating. Beetles, for example, and other kinds of bees like honeybees. And those native species are being driven out by honey bees, which are originally from Europe.

“I think it’s a mixed bag. They have benefits to people, for certain. And from a human perspective, if all you’re concerned about is that your plants get pollinated and you can get the fruits that come from that, it’s a pure positive bag. The negative part of that mixed bag comes when you start to think about native biodiversity.”

But Danoff Burg says preserving native biodiversity maybe doesn’t matter so much in a place like New York. The city’s ecosystem has already been changed so much, and there are other, more wild places where native insects can thrive.

So even though NY is America’s biggest city, it might also be the best place in the country to raise bees. As long as you keep them out of sight of the law.

Hard Times for Honeybees

Beekeepers are continuing to lose their honeybees. About a third of many beekeepers’ colonies have been dying mysteriously each year for the past several years. Rebecca Williams reports researchers think they’re getting closer to an answer:

Honeybees have had some bad luck.

Researchers think there are a couple of things hurting the bees all at once.

They think bees’ immune systems are being weakened.

Maybe because of pesticides. And maybe because bees aren’t getting the variety of food sources they need.

Bees normally collect pollen and nectar from many different plants. But when they’re used on farms, they’re just visiting one kind of plant.

And then on top of that, bees appear to be getting hit by a virus.

Maryann Frazier is a honeybee expert at Penn State University.

She says, until researchers can figure out exactly what’s going on, she expects beekeepers to keep losing a lot of their bees.

“I think what we’re at risk of, more so than the bees dying out, is the beekeepers giving up and not continuing to truck their bees all over the country.”

Beekeepers use honeybees to pollinate about a third of our food supply.

Honeybees are dying at an alarming rate.
Some beekeepers have lost their entire hives.
It’s been tough for food growers too. That’s
because honeybees pollinate up to a third of
the foods we eat. Mark Brush checked in with
a commercial beekeeper to see how pollinating
is going this year:

“Well, there’s twelve months on the calendar and I think we’re busy for thirteen of ’em.”

That’s Dave Hackenburg. He trucks his bees year-round all over the country to pollinate
crops. He says, so far, there have been enough bees to cover most of the crops. But with
bees continuing to die – he’s not sure how much longer beekeepers can keep up.

Hackenburg is convinced that pesticides – known as nicotinoids – are behind the loss in
honeybees.

“I can lay down a road map where bees have been – that have been on these crops where
these products are used – within two to three months afterwards – we start to see the
colonies collapse. Bees that didn’t go to these crops, set out in the woods, away from pesticides, are doing fine.”

Researchers are investigating pesticides as one possible cause. They’re also looking at
viruses, stress, and a lack of genetic diversity as other possibilities.

Urban Beekeepers Creating a Buzz

Honeybees are dying. Sometimes entire hives
are dying and scientists can’t figure out exactly why.
Some people are trying to help, and one of the ways
they’re helping is by becoming beekeepers. Rebecca
Williams reports there are some beekeepers who actually
raise bees in big cities:

Some people call them guerrilla beekeepers. They like to keep their hive locations a secret. That’s
so the neighbors won’t get worried about 60,000 bees living next door.

There are white beehive boxes on rooftops in Paris, Chicago, Manhattan. And there are beehives
tucked into open lots in the middle of downtown Detroit.

(traffic and other neighborhood sounds)

Rich Wieske has been raising bees here for eight years.

“You think of cities as buildings. Detroit’s a little different because there’s been a lot of homes
bulldozed and torn down so there’s a lot of open fields – great for bees!”

Bees have a lot to eat in the city. They love the pollen and nectar from backyard gardens.

Rich Wieske’s just gotten a shipment of bees from California. Today he’s installing new worker
bees and queens into his hives in the corner of an empty lot. He’s one of the people trying to
replace the bees that are mysteriously dying.

This shipment of bees comes packed in wooden boxes – sort of like big shoeboxes – and there are
about 9,000 bees to a box.

(Buzzing)

“Don’t move fast but be warned okay?”

Wieske gives the box a big shake. No kidding – he’s shaking the box of 9,000 bees. They pour
into the hive in a bright orange stream. The bees buzz by our heads, and land in my hair, and fly
up my sleeves.

(buzzing)

But Rich Wieske promises the honeybees are not out to get us. They’d actually rather not sting,
because then they die.

Wieske has a hive he suspects is a little worked up. So he gets out the smoker. It looks like the
love child of a watering can and a miniature accordion. It sends out little puffs of white smoke.

(puffing noises)

“I use lavender, sage, any dried herbs. Also those
chips you find in the bottom of a gerbil cage.”

He waves the smoker around the hive before he lifts the cover off. He says the puffs of smoke
calm the bees down. It covers up the alarm pheromone bees give off, which apparently smells like
bananas if you’re unlucky enough to smell it.

Wieske got into beekeeping with two hives, and now he’s got more than a hundred.

“You’ve got to watch beekeepers. A lot of them become missionaries. You can tell a beekeeper because they love talking about bees, and they’ll talk to anybody about bees
and try to get them to become beekeepers.”

Wieske has a lot of apprentices.

(goose honking)

The next stop on our bee tour is a working farm – right in the middle of downtown Detroit.

Rich Wieske is helping his understudies install new bees in the hives. He’s giving Adam Verville
the same lesson he gave me earlier.

“This is the sort-of scary part.”

(shaking box and buzzing)

Verville says a lot of his friends keep bees in the city.

“People don’t have much money. These projects supplement our incomes essentially by giving us
food and honey.”

There is a lot of honey in beekeeping. Not a whole lot of money though. But the beekeepers say
they feel like they’re part of something bigger.

Stephen Buchmann is a bee expert. He coordinates the group Pollinator Partnership. He says
honeybees pollinate a third of the food grown in the United States. So every beekeeper replacing
disappearing bees helps.

“By having
thousands of people all over the country doing this they have a significant impact on pollinator
declines.”

Buchmann says you don’t have to raise bees in your backyard to help out. He says you can plant
flowers that bees like – like sunflowers and lavender. You can cut down on pesticides in your
yard or use none at all. And you can support your own urban beekeepers by buying local honey.

Life Not So Sweet for Honeybees

For the second year in a row, honeybees are dying at a startling rate. Mark Brush reports
beekeepers are asking the public for help:

Farmers rely on honeybees to pollinate a lot of the food we eat – apples, blueberries,
almonds, soybeans – the list goes on and on.

Beekeepers are losing about a third of their hives each year. The sudden die-off is
known as Colony Collapse Disorder. Researchers are still trying to figure out what’s
making the bees sick.

Dennis vanEngelsdorp is the President of the Apiary Inspectors of America. He says
when the bees get sick, they fly away from the hive to die because they’re social
creatures.

“If you belong to a social group, you don’t want to infect your sisters. And so what we
think is happening. Is these bees somehow are aware that they’re ill, and so they’re flying
away from the colony to die away from the colony.”

vanEngelsdorp says you can help the honeybees by growing plants that bees like in your
backyard, by supporting local beekeepers by buying their honey, or by becoming a
beekeeper yourself.

Bee Colony Collapse Mystery

Scientists are scrambling to find out why honey bee populations are
collapsing. Lester Graham reports, there are a lot of theories. Some
of them are getting more attention than others:


Recently, beekeepers have seen entire colonies of worker bees leave and
never come back to the hive. It’s called Colony Collapse Disorder.
Some news reports have suggested wireless phones or cell phone towers
might be throwing off bees’ navigation.


Barry O’Connor is Curator of Insects at the University of Michigan’s
Museum of Zoology. He says so far, that’s just a theory:


“This phenomenon has been seen in a lot of places where there aren’t
cell phone towers. And so it’s not the whole story if it’s even a part
of the story.”


Other theories for the collapse include stress from moving bees around
to pollinate crops, a newer class of nicotine-based pesticides, a
genetically modified corn with a built-in insecticide, or a combination
of environmental problems.


Growers say food production could drop a lot without honeybees to
pollinate crops.

Bee Keepers Struggle With Declining Markets

Its estimated that the U.S. honeybee industry generates about $8
million in annual revenue. But the industry has taken a serious
financial hit from a mite infestation. Honey bees are being killed and
honey production is down. You might think that would mean higher
prices for honey. But as the Great Lakes Radio Consortium’s Lester
Graham reports, the price of honey has actually gone down:
