I live in bush alaska on the yukon river where we have no cell phones or pesticides and no honeybees.this problem has motivated me to buy a beehive.we have some bees 250 miles east of me in fairbanks but i am to late in the year to purchase them .I would like to maintain a clean colony for my own use and to be able to be part of preserving our honeybees for the future.We do have hot summers and almost 24 hours a day sunshine in late june and would be willing to winter them over somehow when its dark and extremely cold.It has been done in alaska before.Where can I find some clean bees to start with ?ed sarten

Mobile phones and nerve poisoning pesticides may turn the honey bee into
a nervous wreck.

Colony collapse a new phenomenon
Bees worldwide have been involved in a disappearing act called “colony
collapse disorder” over the past two years [1] (Mystery of Disappearing
Honeybees, this series), with little sign of the disease or infestations
that have resulted in massive loss of colonies in the past. The bees
simply leave the hives and fail to return. Beekeepers and scientists
alike are stymied as to the cause of this strange phenomenon.

One likely culprit is a new class of systemic pesticides, which are not
only sprayed on crops, but also used universally to dress seeds in
conventional agriculture, and can confuse and disorientate bees at very
low concentrations [2] (Requiem for the Honeybee, this series). Another
candidate is radiation from mobile phone base stations that has become
nearly ubiquitous in Europe and North America where the bees are
vanishing; this possibility is considerably strengthened by preliminary
findings that bees fail to return to the hives if cordless phone base
stations are placed in them.

Simple experiment with dramatic results
Researchers at Landau University in Germany designed a simple experiment
for students on the Environmental Science course [3]. Eight mini-hives,
each with approximately 8 000 bees were set up for the experiment. Four
of them were equipped with a DECT (Digital Enhanced Cordless
Telecommunication)-station at the bottom of the hive, and the other four
without the DECT-station served as controls.

At the entrance of each hive, a transparent plastic tube enabled the
experimenters to watch the marked bees entering and leaving the hive, so
they can be counted and their time of return after release recorded for
a period of 45 minutes.

The experimenters also studied building behaviour by measuring the area
of the honeycomb and its weight.

In the course of the experiment, three colonies exposed to mobile phone
radiation and one non-exposed control colony broke down. The total
weights of the honeycombs in all colonies, including those at the time
of breakdown were compared. The controls weighed 1 326g, while those
exposed to the DECT-stations weighed only 1 045g, a difference of 21
percent. The total area of the honeycomb in the controls was 2 500,
compared to just 2050 in the exposed hives.

But it was the number of returning bees and their returning times that
were vastly different. For two control hives, 16 out of 25 bees returned
in 45 minutes. For the two microwave-exposed hives, however, no bees at
all returned to one hive, and only six returned to the other.

Cordless phone base station widely used in homes and offices
These dramatic results are of a preliminary nature, but one should bear
in mind that the DECT-station is a simple cordless phone base, widely
used in homes and offices.

It emits microwave radiation of about 1 900 MHz continuously, which is
frequency modulated at 100 Hz. The average power is 10 mW, with a peak
of 250 mW. It represents the exposure levels of perhaps tens of millions
worldwide living near mobile phone base stations, or have cordless
phones in their homes or offices.

The same scientists had carried out an earlier experiment with the
cordless phone base on a standby mode, in which the average power is 2.5
mW, and that appeared to have had no effect on the bees [4, 5].

Clearly the present findings need to be taken much further, but their
significance should not be downplayed for a number of reasons. The
findings are compatible with evidence accumulating from investigations
on many other species including humans, showing that mobile phone
radiation is associated with a range of health hazards including cancers
[6] (Drowning in a Sea of Microwaves, SiS 34). Furthermore, bees are
known to be extremely sensitive to magnetic and electromagnetic fields,
and there have been many suggestions that they could be used as an
indicator species for electromagnetic pollution.

Bees as indicator species for electromagnetic pollution
Experiments dating well back to the last century have documented the
phenomenal sensitivity of honeybees to electromagnetic fields. Bees use
the earth’s magnetic field to navigate. Free-flying honeybees are able
to detect static intensity fluctuations as weak as 26 nT against the
background earth-strength magnetic field (average 500 mT) [7]. This has
been demonstrated in experiments where individual honeybees have been
trained to discriminate between the presence and the absence of a small
static magnetic anomaly in the lab. Honeybees can also learn to
distinguish between two 360o panoramic patterns that are identical
except for the compass orientation. In this case, the difference was a
90o rotation about the vertical axis [8]. The most powerful cue to
direction for the honeybee comes from the sky, but discrimination
between patterns is possible in the absence of celestial information, as
when the sky is overcast. Under those conditions, bees can use a
magnetic direction to discriminate between patterns.

The bees’ waggle dance on the honeycomb, which tells hive mates where to
find food, can also be misdirected by anomalies in the earth’s magnetic
field or very weak pulsed magnetic fields at about 250 MHz applied in
the correct direction [9]. Bees can even learn to detect very low levels
of extremely low frequency alternating electromagnetic fields [10].

But mobile phones have been around for close to 20 years, so why now?
There has been a recent change in cell phone technology that coincides
with the current crisis. At the beginning of the present century, 3G
(third generation) mobile phone systems became publicly available,
leading to a surge in popularity of mobile phones, and many more phone
towers [11]. Bees are disappearing in North America, Europe and also
Australia, wherever mobile phones are greatly in use. Stay tuned.
