- There are several identified problems with bees:
1. California almond orchards(biggest world producer) poisoned all their
bees indirectly through pesticides. Now bees are shipped in from all
over US. Almonds are only pollinated by bees - we're talking millions
2. Most of the devastation in the bees seems to be happening to
commercial bee keepers. Some think the stress of traveling and the
spread of disease due to mingling of bees from all of the country in
California may be a problem.
3. There is a mite that is causing serious problems with bees.

One should be very careful in attributing effects to EM-waves based on
the evidence cited below.
Homing pigeons: Placing magnets on the heads of the pigeons merely
introduces a (solely magnetic, not electro-magnetic) DC (constant) bias
to the external, uniform magnetic field of the earth that it is supposed
that the pigeon senses. Frequency is everything in these issues, and the
frequencies emitted by the antennas (100s of MHz to GHz) are quite
different from those "emitted" by magnets and the earth (zero Hz,
essentially, although technically the actually frequency of the earth
might be on the order of a FemtoHertz or so). The simplest explanation
of the pigeon experiments is that the magnets on the heads of the
pigeons are merely confusing the pigeon about the true direction of the
earth's magnetic field, just as a human relying on a compass would be
confused if his/her compass is too close to another magnetic or a
sufficiently large ferro-magnetic body. EM radiation has nothing to do
Cell phone radiation: I'm unfamiliar with the IEEE article on cell
phone EM radiation, but a number of years ago Physics Today (a magazine
that is to physicists what IEEE Spectrum is to electrical engineers)
discussed the supposed association between cancer and power line EM
radiation. The bottom line is that there was no known physical process
that might have an effect (for example, the energy of the radiation was
insufficient to induce molecular dissociation, from which an increased
rate mutations might result). I think this is true also, at least for
the 2nd paragraph below. If I read it correctly, the photoelectric
effect is cited as something " about which man has no explanation." Not
so; the PE effect was described by Einstein in 1905 and his paper doing
so was one of the seminal developments in the early 20th Century
breakthroughs in quantum mechanics. Again, the EM frequency is
important. Electrons are only dissociated from matter when the photon
energy (a linear function of EM frequency) is high enough to overcome
the work function of the material. I'm no expert in p hotovoltaic
response mentioned below, but again the photon energy (frequency) must
be sufficient to overcome the band gap in these devices. I believe that
typically the required frequencies are in the optical range or higher.
Cell phones, microwaves, etc. operate at much lower frequencies, and
make EM radiation as a mechanism highly unlikely. (Note that microwave
heating is not an ionization phenomenon; it is merely an efficient way
of heating material containing water).
The time signature is important -- Cell phones have been around for
years, and their coverage is extensive. The bee phenomenon, while
extremely alarming and potentially catastrophic, is very recent
(apparently). It is more reasonable to look for the reasons in recent
changes in the environment -- the supposedly harmless pesticides would
seem to be a more likely culprit than some yet-to-be-discovered
mechanism in EM radiation, the physics of which is probably much better
understood than is the chemistry of many pesticides.
The preliminary results for the gamma ray sterilization of hives is
consistent with the existence of a pathogen. Wait and see.

Bees Vanish, and Scientists Race for Reasons
By ALEXEI BARRIONUEVO
BELTSVILLE, Md., April 23 - What is happening to the
More than a quarter of the country's 2.4 million bee
colonies have been lost - tens of billions of bees, according to an
estimate from the Apiary Inspectors of America, a national group that
tracks beekeeping. So far, no one can say what is causing the bees to
become disoriented and fail to return to their hives.
As with any great mystery, a number of theories have
been posed, and many seem to researchers to be more science fiction than
science. People have blamed genetically modified crops, cellular phone
towers and high-voltage transmission lines for the disappearances. Or
was it a secret plot by Russia or Osama bin Laden
laden/index.html?inline=nyt-per> to bring down American agriculture?
Or, as some blogs have asserted, the rapture of the bees, in which God
recalled them to heaven? Researchers have heard it all.
The volume of theories "is totally mind-boggling," said
Diana Cox-Foster, an entomologist at Pennsylvania State University
nsylvania_state_university/index.html?inline=nyt-org> . With Jeffrey S.
Pettis, an entomologist from the United States Department of Agriculture
iculture_department/index.html?inline=nyt-org> , Dr. Cox-Foster is
leading a team of researchers who are trying to find answers to explain
"colony collapse disorder," the name given for the disappearing bee
"Clearly there is an urgency to solve this," Dr.
Cox-Foster said. "We are trying to move as quickly as we can."
Dr. Cox-Foster and fellow scientists who are here at a
two-day meeting to discuss early findings and future plans with
government officials have been focusing on the most likely suspects: a
virus, a fungus or a pesticide.
About 60 researchers from North America sifted the
possibilities at the meeting today. Some expressed concern about the
speed at which adult bees are disappearing from their hives; some
colonies have collapsed in as little as two days. Others noted that
countries in Europe, as well as Guatemala and parts of Brazil, are also
struggling for answers.
"There are losses around the world that may or not be
linked," Dr. Pettis said.
The investigation is now entering a critical phase. The
researchers have collected samples in several states and have begun
doing bee autopsies and genetic analysis.
So far, known enemies of the bee world, like the varroa
mite, on their own at least, do not appear to be responsible for the
unusually high losses.
Genetic testing at Columbia University
umbia_university/index.html?inline=nyt-org> has revealed the presence
of multiple micro-organisms in bees from hives or colonies that are in
decline, suggesting that something is weakening their immune system. The
researchers have found some fungi in the affected bees that are found in
humans whose immune systems have been suppressed by the Acquired Immune
Deficiency Syndrome or cancer
"That is extremely unusual," Dr. Cox-Foster said.
Meanwhile, samples were sent to an Agriculture
Department laboratory in North Carolina this month to screen for 117
chemicals. Particular suspicion falls on a pesticide that France banned
out of concern that it may have been decimating bee colonies. Concern
has also mounted among public officials.
"There are so many of our crops that require
pollinators," said Representative Dennis Cardoza, a California Democrat
whose district includes that state's central agricultural valley, and
who presided last month at a Congressional hearing on the bee issue. "We
need an urgent call to arms to try to ascertain what is really going on
here with the bees, and bring as much science as we possibly can to bear
on the problem."
So far, colony collapse disorder has been found in 27
states, according to Bee Alert Technology Inc., a company monitoring the
problem. A recent survey of 13 states by the Apiary Inspectors of
America showed that 26 percent of beekeepers had lost half of their bee
colonies between September and March.
Honeybees are arguably the insects that are most
important to the human food chain. They are the principal pollinators of
hundreds of fruits, vegetables, flowers and nuts. The number of bee
colonies has been declining since the 1940s, even as the crops that rely
on them, such as California almonds, have grown. In October, at about
the time that beekeepers were experiencing huge bee losses, a study by
the National Academy of Sciences
ional_academy_of_sciences/index.html?inline=nyt-org> questioned whether
American agriculture was relying too heavily on one type of pollinator,
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
pics/diet/index.html?inline=nyt-classifier> that includes artificial
supplements, concoctions akin to energy drinks and power bars. In
several states, suburban sprawl has limited the bees' natural forage
So far, the researchers have discounted the possibility
that poor diet alone could be responsible for the widespread losses.
They have also set aside for now the possibility that the cause could be
bees feeding from a commonly used genetically modified crop, Bt corn,
because the symptoms typically associated with toxins, such as blood
poisoning, are not showing up in the affected bees. But researchers
emphasized today that feeding supplements produced from genetically
modified crops, such as high-fructose corn syrup, need to be studied.
The scientists say that definitive answers for the
colony collapses could be months away. But recent advances in biology
and genetic sequencing are speeding the search.
Computers can decipher information from DNA
pics/geneticsandheredity/index.html?inline=nyt-classifier> and match
pieces of genetic code with particular organisms. Luckily, a project to
sequence some 11,000 genes of the honeybee was completed late last year
at Baylor University
lor_university/index.html?inline=nyt-org> , giving scientists a huge
head start on identifying any unknown pathogens in the bee tissue.
"Otherwise, we would be looking for the needle in the
haystack," Dr. Cox-Foster said.
Large bee losses are not unheard of. They have been
reported at several points in the past century. But researchers think
they are dealing with something new - or at least with something
"There could be a number of factors that are weakening
the bees or speeding up things that shorten their lives," said Dr. W.
Steve Sheppard, a professor of entomology at Washington State University
hington_state_university/index.html?inline=nyt-org> . "The answer may
already be with us."
Scientists first learned of the bee disappearances in
November, when David Hackenberg, a Pennsylvania beekeeper, told Dr.
Cox-Foster that more than 50 percent of his bee colonies had collapsed
in Florida, where he had taken them for the winter.
Dr. Cox-Foster, a 20-year veteran of studying bees, soon
teamed with Dennis vanEngelsdorp, the Pennsylvania apiary inspector, to
look into the losses.
In December, she approached W. Ian Lipkin, director of
the Greene Infectious Disease Laboratory at Columbia University, about
doing genetic sequencing of tissue from bees in the colonies that
experienced losses. The laboratory uses a recently developed technique
for reading and amplifying short sequences of DNA that has
revolutionized the science. Dr. Lipkin, who typically works on human
diseases, agreed to do the analysis, despite not knowing who would
ultimately pay for it. His laboratory is known for its work in finding
the West Nile
pics/westnilevirus/index.html?inline=nyt-classifier> disease in the
Dr. Cox-Foster ultimately sent samples of bee tissue to
researchers at Columbia, to the Agriculture Department laboratory in
Maryland, and to Gene Robinson, an entomologist at the University of
versity_of_illinois/index.html?inline=nyt-org> . Fortuitously, she had
frozen bee samples from healthy colonies dating to 2004 to use for
After receiving the first bee samples from Dr.
Cox-Foster on March 6, Dr. Lipkin's team amplified the genetic material
and started sequencing to separate virus, fungus and parasite DNA from
"This is like C.S.I. for agriculture," Dr. Lipkin said.
"It is painstaking, gumshoe detective work."
Dr. Lipkin sent his first set of results to Dr.
Cox-Foster, showing that several unknown micro-organisms were present in
the bees from collapsing colonies. Meanwhile, Mr. vanEngelsdorp and
researchers at the Agriculture Department lab here began an autopsy of
bees from collapsing colonies in California, Florida, Georgia and
Pennsylvania to search for any known bee pathogens.
At the University of Illinois, using knowledge gained
from the sequencing of the bee genome, Dr. Robinson's team will try to
find which genes in the collapsing colonies are particularly active,
perhaps indicating stress from exposure to a toxin or pathogen.
The national research team also quietly began a parallel
study in January, financed in part by the National Honey Board, to
further determine if something pathogenic could be causing colonies to
Mr. Hackenberg, the beekeeper, agreed to take his empty
bee boxes and other equipment to Food Technology Service, a company in
Mulberry, Fla., that uses gamma rays to kill bacteria on medical
equipment and some fruits. In early results, the irradiated bee boxes
seem to have shown a return to health for colonies repopulated with
"This supports the idea that there is a pathogen there,"
Dr. Cox-Foster said. "It would be hard to explain the irradiation
getting rid of a chemical."
Still, some environmental substances remain suspicious.
Chris Mullin, a Pennsylvania State University professor
and insect toxicologist, recently sent a set of samples to a federal
laboratory in Raleigh, N.C., that will screen for 117 chemicals. Of
greatest interest are the "systemic" chemicals that are able to pass
through a plant's circulatory system and move to the new leaves or the
flowers, where they would come in contact with bees.
One such group of compounds is called neonicotinoids,
commonly used pesticides that are used to treat corn and other seeds
against pests. One of the neonicotinoids, imidacloprid, is commonly used
in Europe and the United States to treat seeds, to protect residential
foundations against termites and to help keep golf courses and home
In the late 1990s, French beekeepers reported large
losses of their bees and complained about the use of imidacloprid, sold
under the brand name Gaucho. The chemical, while not killing the bees
outright, was causing them to be disoriented and stay away from their
hives, leading them to die of exposure to the cold, French researchers
later found. The beekeepers labeled the syndrome "mad bee disease."
The French government banned the pesticide in 1999 for
use on sunflowers, and later for corn, despite protests by the German
chemical giant Bayer, which has said its internal research showed the
pesticide was not toxic to bees. Subsequent studies by independent
French researchers have disagreed with Bayer. Alison Chalmers, an
eco-toxicologist for Bayer CropScience, said at the meeting today that
bee colonies had not recovered in France as beekeepers had expected.
"These chemicals are not being used anymore," she said of imidacloprid,
"so they certainly were not the only cause."
Among the pesticides being tested in the American bee
investigation, the neonicotinoids group "is the number-one suspect," Dr.
Mullin said. He hoped results of the toxicology screening will be ready
within a month.
