"This is certainly the worst die-off that I’ve seen in my experience working
with honey bees. It may be the worst die-off that has ever occurred with honey bees
since they’ve been introduced into the United States since the 1620s."
– Maryann Frazier, Honey Bee Specialist, Penn State
Western honey bees, or European honey bees (Apis mellifera), gather nectar from
the blooms of fruits, vegetables, nuts, melons and many other food crops for the production
of honey in wax combs. Millions of honey bees in 22 American states, Spain and Poland
have been disappearing at an alarming rate with no explanation to date, threatening
pollination of one-third American food crops. Bee image © 2007 by

February 23, 2007 Pennsylvania – Most people don’t realize that honey bees pollinate about one-third of our food supply around the world. Honey bees pollinate apple trees and berry bushes, vegetables, melons, almonds and many other food sources. Honey bees were originally brought from Europe to the United States in 1620. Periodically since then, there have been occasional die-offs of honey bees, mostly attributed to mites.

honey bees in the past, but do not seem to be the answer to honey bee disappearances now.

But according to the scientists, beekeepers and government agency bee specialists I’ve talked to recently, there have never been so many empty, deserted honey bee hives as there are now. And no one knows why.
The past year in America, at least 22 states have reported honey bee disappearances. Government and science authorities are calling it "Colony Collapse Disorder (CCD)." Beekeepers have reported losses ranging from 60% to 100% of their bee colonies. As winter changes to spring and beekeepers in the colder Northeast can open their hives again, it's expected there will be many more empty hives.
Strangely, honey bees have also been disappearing in huge numbers in Spain and Poland. Adding to the European mystery is that Spain has very large commercial beekeeper operations with at least 3 million colonies of honey bees, similar to the United States. But Poland’s 400,000 hives are largely raised on individual farms where smaller bee colonies are separated from each other. If the answer were disease, you would not expect Poland’s separated hives to be plagued by large numbers of honey bee disappearances as in Spain and the United States.
The two European countries with the largest honey bee populations are France and Italy. It might be significant that those two countries banned certain pesticides in recent years because beekeepers there became convinced that systemic pesticides were killing off honey bees. And so far, neither France nor Italy has yet reported the collapse of honey bee hives.
One scientist who has been studying honey bees at Penn State University for the past eighteen years is Maryann Frazier. I asked her how serious she thinks the honey bee disappearances are.
Maryann Frazier, M. S., Honey Bee Extension Specialist, Dept. of Etymology, Penn State University, College Park, Pennsylvania: “I would say this is certainly the worst die-off that I’ve seen in my experience working with honey bees. It may be the worst die-off that has ever occurred with honey bees since they’ve been introduced into the United States since the 1620s.
It’s characterized by the bees being there in the colony quite healthy and strong on one day and then within a week to two weeks, the beekeeper goes back and the bees have disappeared from the colony. Sometimes (there will be) a queen and a small number of bees – often times there is brood, which is the young, developing bees. Some how the bees have just gone and we assume died outside the hive. There is no evidence that the bees have congregated anywhere, or tried to swarm – there is no evidence of that. The bees are just missing! A very unusual kind of situation.
WE’RE TALKING THEN ABOUT THE MYSTEROUS DISAPPEARANCE OF BEES IN THE MILLIONS AND THAT MUST PRESENT A PROBLEM IN DOING SOME KIND OF AUTOPSY TO FIND OUT WHAT IS HAPPENING?
That’s right. It is very difficult to find out what is happening. We do have some strong leads about what might be happening and that has come from beekeepers who we have interviewed at great length and tried to come up with common threads, things these beekeepers might have in common that might explain some of what is happening."
Beekeeper Suspects Systemic Pesticides
One of those large American beekeepers is David Hackenberg, owner of Hackenberg Apiaries in Lewisburg, Pennsylvania. Mr. Hackenberg has been raising honey bees for both commercial honey sales and for pollination in Florida and California crops over the past 45 years. He trucks his pollinating honey bees to farmers who hire his pollination services.
Hives of honey bees are loaded on to truck for transport up and down,
and between, American coasts as pollinators for hire.
But in October 2006, something hit his honey bees hard and by the beginning of 2007, he has lost at least 60% of his colonies. Dave Hackenberg suspects that the culprit in this unprecedented honey bee disappearance is systemic pesticides – poisons designed to stay inside plants and kill off insects that damage crops. Systemic pesticides are not supposed to kill off honey bees, but David Hackenberg explains why he thinks that’s the problem.
David Hackenberg, Owner, Hackenberg Apiaries, Lewisburg, Pennsylvania: “We move bees up and down the East Coast. We moved the last of our bees in October 2006. And a month later, in early November, we went out to look at some bees and the first location we found had disappeared. It had 400 hives of bees in it and in less than four weeks, they had just disappeared. Empty boxes. No dead bees on the ground. No dead bees anywhere.
SO IT IS REALLY A DISAPPEARANCE MORE THAN A DIE-OFF BECAUSE YOU DON’T HAVE BODIES?
That’s absolutely right! The bees have died – I mean they’ve died some place, but nobody knows where they are – whether they flew off a mile or two miles or what to die. I mean, we just don’t know how far out they are going.
IN THAT FIRST DISAPPEARANCE OF ALL THOSE BEES FROM YOUR HIVES, HOW MANY BEES DID YOU LOSE?
Those beehives would have had somewhere around 20,000 or 30,000 bees per hive and if you take that times roughly 400, you’re talking about millions of bees disappearing.
WHAT HAVE YOU SEEN DISAPPEARING SINCE THE FALL?
We had 2900 hives of bees here in October 2006, and we’re down to less than 1,000 now. So, we’ve lost some 60% of them.
HAVE YOU EVER HAD THIS HAPPEN BEFORE?
No, this is the worst thing that’s ever happened to us. I’ve seen a lot of things come down the pike. I’ve been through mites. I’ve been through fires. I’ve been through floods. I’ve had warehouses burn to the ground. I’ve had 10 feet of water in my warehouse. And I know what caused that! And I know what caused the fire. And I know what caused the problem we had with mites. But the problem here (now) is that we don’t know – I just shudder to think what things might look like next year.
In this case, the thing that is really amazing is that (normally) other bees will come in and rob out the honey that’s left and there are a few predators. Here in the south, we have a hive beetle that moves in and we have a wax moth that moves in and starts eating up comb and stuff. The interesting thing about this whole thing is that none of these (normal) things happen. The bees do not bother these (deserted) combs. They (honey combs) literally sit there for weeks and they (other bees and insects) don’t come to take the honey out of the boxes; the beetles don’t bother them; the wax moths don’t bother them. So, it’s just like there is something in there that’s repelling everything else.
AS IF THE HONEY ITSELF THAT WAS MADE BY ALL OF THE BEES THAT HAVE DISAPPEARED IS GIVING OFF SOMETHING THAT OTHER NORMAL PREDATORS AND BEES ARE STAYING AWAY FROM?
Honey bee comb filling up with honey processed from pollen the bees
have gathered from flowers. Normally, if honey bees disappear from a hive, beetle
and wax moth predators will move in to eat. But in the Colony Collapse Disorder syndrome,
beekeepers say even predators are staying away from the empty hives.
There’s something in the hive. We’re pretty sure the honey is not the problem because once you air out this hive for a day or so, they (other bees) will take the honey. And if you air the hive out, the beetles, wax moths and everything else will take over. So, there’s some toxic odor, some other – fortunately some of these colonies are still living and we found this here in Florida and we beat if back to Penn State with it – and thinking basically we had a new virus problems, but found out the bees are full of a fungus. And we think this fungus is giving off some toxins. Personally I think the fungus is probably secondary from something else – poisonous pollen or something that was gathered by the bees.
DAVE, WHAT WOULD IT MEAN IF THERE WAS SOME KIND OF CONTAMINATED POLLEN IN 22 STATES?
It actually means that there is probably a big problem out here. It’s probably a lot wider than most of us want to think about. There’s a possibility that there’s some new insecticide or some new something that is being applied to the crops or being used, but is being transferred into this pollen that bees are gathering and bringing back to the hive – that it’s coming up through the plant, remains to be seen. But it sure appears that way. There are new products out there that are systemic, which means they stay in the plant. So, not only staying in the plant, but it’s probably going in the food that we’re eating and the animals are eating and everybody else is eating with really serious ramifications to this thing.
THAT WE COULD BE JUST AT THE TIP OF AN ICEBERG HERE?
Personally, I think that’s the case. I’ve had several people in Washington, D. C., in the last several months telling me that honey bees are a canary for the human race. The canary is what was used in mines to see whether there was oxygen, or not enough oxygen, for the miners. If the canary fell over, why it was time to get out. And Penn State has already found it looks like the immune system has been broken down on these honey bees. So, if the immune system is broken down and this stuff is going into our food supply, how much does it take to take out humans?
You know, I hate to be pessimistic about the situation, but it just doesn’t appear good.
RIGHT, AND WHAT HAPPENS IF ALL THE HONEY BEES DISAPPEAR?
First of all, a third of the food supply in the United States – and actually the world – a third of the food supply is directly related to the honey bee: fruits, vegetables, nuts, just a lot\ of stuff that we eat, that we’re accustomed to have every day, the honey bee is directly responsible for it. And then, there is probably another 30% of what we consume that honey bees are indirectly responsible for. Take the milk we drink. The cows have to have hay. They’ve got to eat clover and alfalfa to produce milk. And if you go back and listen to what (Albert) Einstein told us – he said if the honey bees disappeared off the face of the Earth, within four years, all life would be gone. Even the wildlife depends on plants pollinated by the honey bees for berries and so on. So, it’s not just humans not being able to get apples and carrots. We’re talking about a real big, serious problem!
WHEN YOU TALKED WITH THE PEOPLE IN THE GOVERNMENT AND THEY SAID THE HONEY BEES WERE LIKE A CANARY DOWN IN THE COAL MINE WARNING THAT IF THE BIRD DIED, THEN THE MINERS MIGHT DIE – WHAT DID THE GOVERNMENT PEOPLE SAY THAT THEY THOUGHT MIGHT BE THE PROBLEM?
They really don’t know. That was in the preliminary stages, but that’s the first time in my 40 some years of beekeeping that anybody had ever said that to me. I mean that was something I’d never heard before.
WHAT YOU MEAN IS THAT OUR ENTIRE FOOD SUPPLY, NOT ONLY IN THIS COUNTRY, BUT ALSO IN OTHER PARTS OF THE WORLD, COULD BE THREATENED AS THE HONEY BEES AND OTHER BEES ARE THREATENED BY WHATEVER IS KILLING THEM?
Yes, that’s exactly right. And actually, we’re hearing from Europe now that Poland and Spain – they have lost astronomically large numbers of bees this past fall.
Even with the losses we’ve got now, there are guys that are telling me there’s no way they are going to be able to replace the losses they have this year. So, if you can’t replace the losses you’ve got this year, and you have another loss on top of it next year, you’re headed down a bad, bad way, that’s all!
AND ESPECIALLY IS IT IRONIC, DAVE, IF THE CULPRIT IS THE CHEMICALS IN PESTICIDES THAT HAVE BEEN DEVELOPED TO ALLOW FARMERS TO GROW CROPS AND IT ENDS UP KILLING THE POLLINATORS.
Disappearing Pollinators –
Could There Be Food Shortages in 2007?
I asked the Acting State Apiarist in Pennsylvania’s Department of Agriculture if he expects any food shortages this year because of the honey bee crisis and what he thinks worst case might be in 2007?
Dennis vanEngelsdorp, M. S., Acting State Apiarist, Pennsylvania Department of Agriculture, Harrisburg, Pennsylvania: “This situation is unique because we’re not sure what the underlying cause is.
WOULD YOU SAY YOU MIGHT HAVE AN ANSWER IN MARCH?
I think we’ll be able to rule some things out by March. I would be very surprised right now if there was a very large shortage to meet East Coast needs this year. However, if we can’t figure out how to identify this problem, or solve this problem, we could not sustain a loss like this again. That is what differentiates this loss from past losses from the Verroa mite and Honeybee Tracheal mite losses because there is not that number of bees to fill in the void anymore.
AND SO WHAT IS WORST CASE AND WORST CASE CONSEQUENCES?
I think this is a worst case for the beekeepers who experience 80% to 90% loss. That’s terrible! There was one Pennsylvania beekeeper who spent $15,000 to move his colonies to California for almond pollination, and he’s bringing nothing back but dead hives. And that’s worst case for him.”
Mr. van Engelsdorp at the Pennsylvania Dept. of Agriculture has joined up with Penn State researchers, the U. S. Department of Agriculture, the Florida Dept. of Agriculture, and organizations such as Bee Alert affiliated with the University of Montana, to study what is happening to honey bees. The study group recently wrote that the honey bee Colony Collapse Disorder “threatens the pollination industry and production of commercial honey in the United States.” Even honey bees brought here from Australia – to fill in for the disappearing American honey bees – have also disappeared.
Until there is an answer to what is causing the honey bees to leave their hives and never return, it’s possible that eventually there will be honey and other food shortages.

Wikipedia Background: Honey bees (Apis mellifera) are a subset of bees which represent a far smaller fraction of bee diversity than most people suspect; of the approximately 20,000 known species of bees, there are only seven presently-recognized species with a total of 44 subspecies historically, anywhere from six to eleven species have been recognized). These bees are the only living members of the tribe Apini, all in the genus Apis, and all of which produce and store liquefied sugar ("honey") to some degree, and construct colonial nests out of wax secreted by the workers in the colony. Other types of related bees produce and store honey, but only members of the genus Apis are considered true honey bees.
Apis mellifera, the most commonly domesticated species, is the third insect to have its genome mapped. It originated in Tropical Africa and spread from there to Northern Europe and East into Asia. It is also called the Western honey bee. There are many sub-species that have adapted to the environment of their geographic and climatic area. Behavior, color and anatomy can be quite different from one sub-species or race to another.
In 1622, first European colonists brought the sub-species Apis mellifera mellifera to the Americas. Many of the crops that depend on honey bees for pollination have also been imported since colonial times. Escaped swarms (known as wild bees, but actually feral) spread rapidly as far as the Great Plains, usually preceding the colonists. The Native Americans called the honey bee "the white man's fly." Honey bees did not naturally cross the Rocky Mountains; they were carried by ship to California in the early 1850s. The so-called "killer bee" is a strain of this species, with ancestral stock of African origin (thus often called "Africanized").
