Earth Life Threats -

Alarming Disappearance of Honey Bees

"This is certainly the worst die-off that Iíve seen in my experience working
with honey bees. It may be the worst die-off that has ever occurred with honey bees
since theyíve been introduced into the United States since the 1620s."

Western honey bees, or European honey bees (Apis mellifera), gather pollen 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.

February 23, 2007  Pennsylvania - Most people donít 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.

But according to the scientists, beekeepers and government agency bee specialists Iíve 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 Polandís 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 Polandís 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: 

 

ďI would say this is certainly the worst die-off that Iíve seen in my experience working with honey bees. It may be the worst die-off that has ever occurred with honey bees since theyíve been introduced into the United States since the 1620s.

 

Itís 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 Ė 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 Ė there is no evidence of that. The bees are just missing! A very unusual kind of situation.

 

We are talking then about the mysterious disappearance of bees in the millions and that must present a problem in doing some kind of autopsy to find out what is happening?

 

Thatís 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 Ė 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 thatís the problem.

 

David Hackenberg, Owner, Hackenberg Apiaries, Lewisburg, Pennsylvania:

ďWe 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?

Thatís absolutely right! The bees have died Ė I mean theyíve died some place, but nobody knows where they are Ė whether they flew off a mile or two miles or what to die. I mean, we just donít know how far out they are going.

 

In that first disappearance of all those bees from your hives, how many 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, youíre 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 weíre down to less than 1,000 now. So, weíve lost some 60% of them.

 

Have you ever had this happen before?

No, this is the worst thing thatís ever happened to us. Iíve seen a lot of things come down the pike. Iíve been through mites. Iíve been through fires. Iíve been through floods. Iíve had warehouses burn to the ground. Iíve 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 donít know Ė 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 thatís 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) donít come to take the honey out of the boxes; the beetles donít bother them; the wax moths donít bother them. So, itís just like there is something in there thatís 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.

 


Thereís something in the hive. Weíre 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, thereís some toxic odor, some other Ė 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 Ė 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. Itís probably a lot wider than most of us want to think about. Thereís a possibility that thereís 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 Ė that itís 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 itís probably going in the food that weíre 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 thatís the case.  Iíve 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 doesnít 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 Ė and actually the world Ė 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 weíre 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. Theyíve got to eat clover and alfalfa to produce milk. And if you go back and listen to what (Albert) Einstein told us Ė 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, itís not just humans not being able to get apples and carrots. Weíre 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 thought might be the problem?

 

They really donít know. That was in the preliminary stages, but thatís the first time in my 40 some years of beekeeping that anybody had ever said that to me. I mean that was something Iíd 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, thatís exactly right. And actually, weíre hearing from Europe now that Poland and Spain Ė they have lost astronomically large numbers of bees this past fall.

 

Even with the losses weíve got now, there are guys that are telling me thereís no way they are going to be able to replace the losses they have this year. So, if you canít replace the losses youíve got this year, and you have another loss on top of it next year, youíre headed down a bad, bad way,  thatís all!

 

And especially is it ironic, Dave, if the culprit is the chemicals in pesticides that have been developed to allow farmers to crow crops and it end up killing the pollinators. 

 

Thatís right.Ē

 


 

Disappearing Pollinators -
Could There Be Food Shortages in 2007?


I asked the Acting State Apiarist in Pennsylvaniaís 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: 

 

ďThis situation is unique because weíre not sure what the underlying cause is.

 

Would you say you might have an answer in March?

I think weíll 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 canít 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. Thatís terrible! There was one Pennsylvania beekeeper who spent $15,000 to move his colonies to California for almond pollination, and heís bringing nothing back but dead hives. And thatís worst case for him.Ē

 

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 ďthreatens the pollination industry and production of commercial honey in the United States.

 

Ē 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, itís possible that eventually there will be honey and other food shortages.
