EDITORIAL Back
to top
And so we are three years old. Seems more like a
hundred actually, but then as all editors of monthly magazines
will know, it can be a close run thing getting everything together
in reasonable time, and time which of course is relative, speeds
up more and more as deadlines approach. It never seems to stop.
It is necessary therefore to foster a keen bunch of contributors
who are willing to share their knowledge of bees with us, on the
web in our case, and as you may have seen over the years, we have
just that, which makes my life considerably easier. Readers will
have noticed the same names appearing in numerous issues and to
these stalwarts I give my thanks. We need more. But any magazine
is nothing without its readers and your numbers are growing month
by month. It means I hope that we are not getting it all wrong,
but I must ask the question: ‘are we getting it all right?’ and
to know this I rely on you the reader to tell me. Please do so
and help us to improve and grow in the years to come as we move
slowly (very slowly I hope) towards ten.
In this issue, we again move around from pillar
to post looking at a wide variety of subjects from surprise genetics,
bee attacks and Kashmir Bee Virus, right through to the delightful
poem of the month which deals with the aristocracy of clover. It
is not often that our supposed mastery of a subject is shot to
bits, but a tiny weed has done just this in the case of our knowledge
of genetics. And we return to the unusual in the recipe section
with a Mayan recipe. The Maya were of course one of the ancient
powers of Cental America, rivalling the Inca and the Aztecs. Their
temples and civilisation are now marvelled at by modern day man.
They were however supreme beekeepers (of stingless bees) and they
were known as ‘The people of the land and the bee’.
They even had bee gods.
We learn in this issue (if you didn’t already
know) that Kashmir Bee Virus is now in the UK. This of course was
inevitable and I think not too worrying. I have kept bees commercially
in two countries that have it (Spain and New Zealand) and have
rarely even thought about it let alone worried about the beast.
I’m
no expert on the subject of virus particles but I reckon that if
you keep on top of their probable vector varroa, and maintain good
husbandry, there is little to worry about. If you don’t,
then you are going to have many more problems anyway and KBV could
seem like the least of your worries. Personally, I’m more
anxious about bee-eaters, forest fires and AFB – and of course
worrying about whether the local bar will still be open when I’ve
finished shifting bees for the night.
Have you ever wanted to date a bee? Probably not,
but in the US (where else) they have set up a bee dating service
on the net that marries up pollinators and orchardists. (See news
item below). The current drastic shortage of honey bees in the
US has brought about this move which it is hoped will enable a
better and more efficient use of the ever dwindling supply of bee
colonies available for pollination services. They really do seem
to have a problem over there.
As we approach Apimondia 2005, we feature in this
issue a photo article on an aspect of beekeeping in Ireland put
together and sent to us by the County of Dublin Beekeepers Association.
Now receiving this type of input truly delights me. It is interesting,
practical and an excellent example of the type of activity that
local associations get up to. We at Apis-UK are always interested
in what beekeepers get up to (with bees that is) and if you have
a story to tell in words and/or photos, please send it in.
The bee scene on the net is becoming more active.
The Dublin Beekeepers Association mentioned above now have a web
based beekeeping news letter as do one of the Melbourne Beekeeping
Associations. Do look them up. Each has a message board and
from each, you will learn something. This increase in the number
of web magazines/newsletters for beekeepers is good, and far from
being rivals to Apis-UK they are complementary. Any increase in
the number of organs that promote beekeeping and beekeeping knowledge
is welcome and I certainly learn something from every newsletter
that I read.
And the hero of Bees for Development finished his marathon. I
can only admire someone who can manage to run so far, especially
in a bee suit. I once tried a marathon many years ago and after
a few stiff gin and tonics to harden the spirit; I set off at the
gallop and lasted a mere eleven miles. I fell apart in a phone
box, was taken home and couldn’t move properly again for
weeks. So well done to Bill Turnbull. I know what it feels like.
And so may I welcome you to our third anniversary edition of
Apis-UK with the sincere hope that you will enjoy reading it. Keep
in touch.

CUBA INCREASES EXPORTS OF ECOLOGICAL
HONEY
As a producer of organic honey in Spain,
this news is especially interesting to me. (Ed).
Cuba’s
economy is increasing exports of ecological bee honey, as part
of a strategy aimed at meeting the growing demand for that product
in the international market. Experts said that production of
ecological honey increased last year, and new areas were certified
to produce that kind of honey. At present, a score of municipalities
in eastern Cuba have been certified to produce ecological bee
honey, since they meet international quality standards. Ecological
honey is highly demanded in Europe and prices are high in the
international market; that is why, Cuban agricultural authorities
have decided to increase production of that kind of honey. In
order to achieve that goal, Cuban apiculturists are gradually
increasing the value of production, since the price of one ton
of ecological honey is 300 dollars higher than that of regular
bee honey in the international market. The highly-demanding European
market, where there is a growing tendency to consume ecological
products, is the main target for Cuban exports of ecological
honey.
KASHMIR BEE VIRUS HITS THE UK
In an earlier edition
of Apis-UK we reported on the NBU’s
investigation into bee virus’s. This investigation has
now discovered the first known incidence of kashmire Bee Virus
in Manchester and Hull. The colonies were normal and this suggests
that the virus had been there for some time. (See fact File
in this issue for further information on this virus. Ed).
PHILIP MCCABE'S BEE BEARD
The Irish Development Aid organisation, Bóthar and Bees
for Development Trust are actively involved in providing
beekeeping programmes and advice to poor families struggling
to survive throughout the developing world. A unique world
record attempt is giving both organisations an opportunity
to raise much-needed funds. In June, Philip McCabe, Chairman
of Apimondia Ireland 2005 and President of the Federation of
Irish Beekeeping Associations, will attempt to wear a beard
of 500,000 bees in an effort to enter the Guinness Book of
World Records. The current world record is held by Mark Biancaniello,
who was covered by bees weighing an estimated 50 kg, calculated
at over 350,000 bees. This fund-raising opportunity has been
created to mark the fact that the 2005 Apimondia Congress is
taking place in Ireland (details on page 8 of the March BfDJ).
Please sponsor Philip in his record-breaking attempt: funds
raised will be shared equally between Bees for Development
Trust and Bóthar.

ATTACK ON BEES IN CAMBRIDGESHIRE
Thousands of bees have died after vandals set off a firework
inside a hive in Cambridgeshire last month. Rowena Guthrie and
her mother Caroline, have kept bees at a site in Caldecote for
the past 18 months. They described the damage as "horrendous".
Two of the hives were bombarded with bricks and a firework was
set off inside another during the attack. Cambridgeshire Police
are investigating the incident and plan to use the firework as
evidence.
FASTEST BEEKEEPER
Bill Turnbull completed
the London Marathon, wearing a beekeeper’s
suit complete with veil, on Sunday (17th April 2005) in just
over four and a half hours. According to Bill: ‘The beekeeping
suit was terrific - people cheering every step of the way -
many saying "Oh - Bees for Development -
what's that?"’ Bill has raised over £3,500
in sponsorship for the Bees for Development Trust!
As well as proving himself the fastest beekeeper in the London
Marathon. Thank
you, everyone that sponsored Bill. News from the BBKA

BEE 'DATING SERVICE' WEBSITE STARTS
A severe loss of beehives
in the Mid-Atlantic region over the past few years has led to
the Virginia Department of Agriculture and Consumer Services
setting up a special Web site to help farmers get in touch with
beekeepers.
“Yes, it is that bad,” said Keith Tignor, VDACS
state apiarist. “We’ve been getting a lot of calls
from farmers to help them find bees.” It’s particularly
difficult in early spring for apple growers, Tignor said, because
out-of-state beekeepers are less inclined to travel and there
are few Virginia beekeepers left who rent the use of their hives
to farmers.
“Most Virginia beekeepers are hobbyists, so they probably
don’t have more than 10 hives for their hobby and a little
honey production. Even so, we’re encouraging them to make
their hives available for pollination, working with other beekeepers
to help the farmers out.”
Tignor said most orchards or vegetable fields require at least
one bee hive for every 2 acres for effective pollination. So
a 100-acre orchard would need at least 50 bee hives, spread
throughout the property.
Bees are the primary pollinator of all fruit and vegetable
crops in the United States . A 2000 Cornell University study
estimated the value of honey production in that year to be about
$250 million, Tignor said. But the value of pollination by the
bees was about $14.5 billion.
Using the multiplier formula from the Cornell study, Tignor
said the $30.8 million in cash receipts the Virginia Agricultural
Statistics Service says Virginia apple growers received in 2002
would have shrunk by some $23 million without honey bees. Using
that same formula for other 2002 Virginia crop yields, he estimated
the value of bees to be $4.5 million for cucumbers, $2.2 million
for peaches and $1.5 million for watermelons.
Virtually all wild or feral bees in Virginia have been wiped
out by several pests over the past decade, Tignor said. Even
domesticated hives have been devastated by the varroa mite and
the trachea mite, and beekeepers have to buy new queens and
hives from out of state each season. If you keep bees and are
interested in renting them to a Virginia farmer, visit http://www.vdacs.virginia.gov/plant&pest/pollinator.html
WAX MOTH CHEMICAL CAUSES CHEMICAL SCARE IN GREECE
Fallout
grew in the northern Peloponnese area of Greece recently from
the latest health scare that involves tainted honey. Development
Ministry inspectors started overseeing the removal from shops
of local honey brands found to contain high levels of parabichlorobenzene
- a chemical used by beekeepers to kill off a kind of moth that
attacks hives during storage. A total of 21 brands have been
found to be over the limit. All tainted products are expected
to have been recalled by tomorrow.

THE YOGHURT MAKERS’ REVENGE
We received this letter from Roger White in Cyprus concerning
the parlous state of beekeeping on the island
- and indeed his wife's freedom. I’ve decided to put it
as a news item – as
it is indeed news. (Ed).
Hello Everyone, It's me again with my news from this part of
the world. We are slowly recovering from the antibiotics shock.
We still have to go to court and it could mean up to 2,000 pounds
in a fine and six months in jail. The honey was marketed under
my wife's name - imagine what will happen if she gets put inside...
anyone want to be a wife for six months? The scandal has continued
and is now affecting Greece. Greek beekeepers used a chemical
crystal called Paradichlorobenzene to protect their combs from
wax moth damage when the combs were stored away from the bees.
The PDB was absorbed by the wax and contaminated the honey.
The Greek government set a maximum limit of 40ppb. a couple
of years ago. Recently a dairy company was found to have mould
in 700,000 containers of yoghurt and EFET (the Greek food safety
agency) ordered the company to remove its product from the market.
They reacted by spilling the beans about the PDB in the honey
and the EU had to intervene by setting a limit of 10ppb. This
means that thousands of tons of Greek honey has to be disposed
of. All this started because of two Cypriots arguing in an office
in Nicosia. Don't you just love it! - one scandal after another
- The Electricity Authority/Foresty products/Cyprus Airways
pilots and several other organisations put their trust in a
certain stockbroker called Mr. Andronikou (Andrew the winner)
who in collaboration with another individual, who goes under
the even more unlikely name of Mr. Koumeras (Mr. Bridesmaid),
managed to ''misplace'' about 10 million pounds ($20,000,000)
worth of shares that they were managing for the pension funds
of the above organisations and as they had a valid power of
attorney it doesn't look like they are going to court over it.
Of course some high powered bright spark has come up with the
idea that the shortfall should be made up by a surcharge on
everyone’s'
electricity bill. It's a waste of time watching films here -
the news is much better entertainment!. Keep well all of you.

VARROA UPDATE
New Test for Detecting Pesticide-Resistant
Mites
Beekeepers
now have a fast new way to check Varroa mites for this honeybee
parasite's resistance to the pesticides coumaphos and fluvalinate.
Scientists at the Agricultural Research Service (ARS) entomologists
in Beltsville, USA have developed a "do-it-yourself" bioassay
that determines, within six hours, whether Varroa mites are
fully resistant to the pesticides, are approaching resistance,
or are still vulnerable.
ARS entomologists sought to devise a faster, cheaper and more
user-friendly alternative to current methods of checking for
pesticide-resistant Varroa mites. These methods are labour-intensive
affairs that require specialized equipment and the shipping
of mite-infested bees. The bioassay is intentionally low-tech.
Its main parts include glass canning jars in which to contain
honeybees, mesh lids through which mites on the bees can fall
out and be counted, and index cards that hold strips of either
coumaphous or fluvalinate.
A mathematical formula determines the mites’ resistance
levels or susceptibility to the pesticides. For example, if
the chemicals kill 25 percent of the mites, then the parasites
can be considered fully resistant. However, if more than 50
percent are killed, then the mites are still vulnerable to the
pesticides. This means the pesticide treatments should still
be effective against the mites.
In the USA some state bee inspectors have already used the
bioassay to document mite resistance in applying for emergency-use
exemptions on alternative control products. They're also using
it to monitor the spread of pesticide-resistant mite population.

WEED DEFIES GENETIC THEORY
Genetics is a subject
very dear to the average bee breeder’s
heart, but if you think you knew all about genetics, read this.
Gregor Mendel described our universally accepted laws of
inheritance in the mid 1800s and according to these ‘Mendelian’ laws,
our characteristics are determined by unique units of inheritance
that are passed on intact from one generation to another. Or
are they? Scientists at the Purdue University in the USA have
discovered that the classic rules do not apply to a tiny weed
called Arabidopsis thaliana which has bypassed genetic abnormalities
carried by both parents and reverted to normal traits from
the grandparents. One of the molecular geneticists at the university,
Robert Pruitt explained that this means that inheritance can
happen more flexibly than we thought in the past, and that
while our school lessons on mendel’s laws remain sound,
they are not absolutes.
They believe that if this mechanism is discovered in animals,
they may be able to use gene therapy to treat diseases in plants
and humans.
The scientists found that a mutant arabidopsis which has
two copies of the altered gene, let it seed and then plant
the seeds, 90% of the offspring will look like the plant but
10% will resemble the normal grandparents. They say that this
challenges everything that they believed in.
NEW STUDY FINDS THAT HONEY MAY AID IN ABSORPTION
OF CALCIUM
A new study conducted at Purdue University
showed that consuming honey along with supplemental calcium enhanced
calcium absorption in rats. In addition, the absorption of calcium
was increased as the amount of honey was increased. The study,
led by Dr. Berdine Martin of Purdue University, was presented
at the Federation of American Societies for Experimental Biology
meeting this month in San Diego.
“Many adults struggle to get the recommended amounts
of calcium in their daily diet,” said Dr. Katherine Beals,
nutrition consultant to the National Honey Board.
According to the recently released US Surgeon General’s
Report on Bone Health and Osteoporosis “By 2020, half
of all American citizens older than 50 will be at risk for
fractures from osteoporosis and low bone mass if no immediate
action is taken by individuals at risk, health care professionals,
health systems, and policymakers.”
Osteoporosis is often referred to as a “silent” disease
because many of those afflicted are completely unaware that
they suffer from it. In fact, four times as many men and three
times as many women have osteoporosis than report it.
One of the key strategies for reducing the likelihood of
developing low bone mass (and subsequent osteoporosis) is to
consume the recommended amounts of calcium. It is also important
that the calcium consumed be absorbed by the body.
Dietary factors that have been shown to enhance the absorption
of calcium include vitamin D and the sugars found in honey,
specifically glucose, fructose and raffinose, may enhance calcium
absorption. “Although this study was done with rats,
the preliminary results are very compelling,” said Dr.
Beals. “Of course we would have to replicate the experiment
in a human sample to see if the same holds true for people.”

Bees and Gravity (Part 1 of 3)
Although at first glance there seems
little reason why the alignment of natural comb should be governed
by gravity, a line of reasoning may be pursued that suggests bees
may find it an advantage to build comb parallel to the maximum gravitational
deviation experienced in a particular direction. If a piece of comb
is cut in half vertically and viewed end on, the back to back arrangement
of the cells is seen to have a downward slope.
Diagram and photo refer.
It seems reasonable to suppose that this
slight incline is provided to assist in containing the contents within
the cell by the aid of gravity. The comb itself must therefore require
to be vertical.
Gravity for all intents and purposes is taken as a single unvarying
downward force at right angles to the Earth's surface, but strictly
speaking this is not exactly the case. There are in fact minute variations
in the general East - West direction which may be detectable by the
bee and therefore influence comb construction.
Beekeepers who own small boats will be aware, even in the Mediterranean,
of their local tides and perhaps even the cause of 10 metre tides
in the Bristol Channel.
The U.K. has a unique tidal pattern where the tides sweep down
the East coast at the same time as they sweep up the West coast.
This causes a tidal tilt which further enhances the East - West gravitational
changes caused by the rotation of the Moon and Sun.
In short there is a small change in the angle of the vertical component
of gravity in the East - West direction which may be detectable by
the bee and cause the East - West comb alignment. This as a theory
may be tested. Ian Rumsey
Rock of Ages
One of the enduring giants of beekeeping
is the Rev Lorenzo Lorraine Langstroth whose moveable frame hive
did so much to revolutionize beekeeping that it is still in use
unfazed by later imitators, innovators and improvers 150 years
after he patented it.
I thought it might be of interest to look at some aspects of
his life that don’t usually appear when people are talking
about his hives. You can read his excellent book
“Langstroth’s Hive and the Honeybee,” which
will give you hours of enjoyment and impress upon you the man’s
great attention to detail, easy style of communicating and deep
religious conviction but is characteristically modest about his
own abilities outside of beekeeping. A paper on his life by Ophia
D Smith of the Ohio Historical Society gives many details of his
life and times in Oxford Ohio and is worth reading in full.
Langstroth was born the eldest son of John George Langstroth
in Philadelphia on Christmas Day, 1810. His parents already had
one child, a girl and he was to have six younger siblings. His
middle name is derived from his mother’s side of the family.
His grandmother was Elizabeth Lorraine Dunn and she was the granddaughter
of Count Louis Lorraine, a Huguenot refugee from France.
Lorenzo showed a great deal of curiosity towards the insect world
in his childhood and he showed early intelligence in the Classics,
reading Latin with great facility. It seems he did not show any
great interest in becoming a clergyman until 1831 after leaving
Yale College and joining Yale divinity school. Thus at the age
of 21 he started to fund his college years by tutoring in mathematics
at Yale and teaching female students at one of the New Haven schools
for girls.
He took up the ministry in Andover, Massachusetts in 1836 but
he did not enjoy good health and the parish was a very large one.
He then went on to be Principal of Abbot Academy in New Haven and
married a local teacher Anne Tucker. His poor health continued
and in 1840 he moved to Greenfield, Massachusetts where apart
from teaching at a girls’ school, he took the pulpit at the
local Congregational Church.
It was in Greenfield that he acquired his first colony of bees
in a log hive, increasing his apiary over the next few years.
He returned to Philadelphia in 1848 following more illness and
took up the post of Principal in another girls’ school for
the next six years. In his spare time he became deeply engrossed
in beekeeping. It was during this time after much study that he
invented his moveable frame hive. A local cabinetmaker Henry Bourquin
who was a fellow bee enthusiast made up his first hives for him
and by 1852 Langstroth had more than a hundred of these hives and
was selling them patented where he could. Later that year he fell
ill again and had to sell his bees. Returning to Greenfield he
offered Dr Joseph Beals a half-interest in the profits in return
for Beals supplying the money necessary for him to market the hives.
Langstroth had temporarily left his wife and two daughters in
Philadelphia where she kept the family going by teaching whilst
he went to Greenfield convinced that he could make a significant
impact on American beekeeping with his new hive. It was there that
he wrote his book which was published the following year. This
book was the first serious work in the English language to reach
a wide audience and apart from his very readable style of writing
was full of information and exactly what was needed by beekeepers.
New editions and many reprints were made over the next 35 years.
Langstroth became a man that commanded great respect amongst eminent
beekeepers like Root, Quinby and Dadant – who in Langstroth’s
fading years undertook a complete new revision on his behalf and
oversaw its translation into numerous languages.
Reunited, his family moved to Oxford, Ohio in 1858 and his widowed
mother joined them there.
Langstroth was a man of enormous charm as well as intellect and
much loved by small children, passing on bee knowledge to them
with great enthusiasm and energy despite his continued poor health.
|
Langstroth at the age of 80 |
He was very much at home in Oxford which prided itself on a genteel
and scholarly way of life. It was here that he imported Italian
bees from Jan Dzierzon in Silesia.
It will be of interest to BIBBA members that Langstroth made
an exhaustive study of native black bees and Italians over a period
of 20 years and considered that in the local conditions Italian
bees were superior. His results were published in the American
Bee Journaland in Gleanings in Bee Culture in
1881. He and his son sold Italian queens at 20 dollars each (a
considerable sum in Victorian times) and in one year sold 100 of
them, many being sent by post all over the United States and arriving
healthy and in excellent condition.
He had some tragedy in his life, his only son James dying at
an early age in 1870 from tuberculosis he had contracted during
the Civil War and his wife dying four years later.
Langstroth was not only a fervent Christian, though never sanctimonious,
but a man who had strong humanitarian beliefs. He was repelled
by the concept of slavery and so much in favour of the Union that
on one occasion when things were going badly for the North he interrupted
his reading of one of the psalms by inserting into it the words
of the Battle Hymn of the Republic.
In 1887 he moved to Dayton, Ohio to live with his daughter Mrs.
HC Cowan and her family. He died there in 1895 as no doubt he would
have wanted to, just as he was delivering a sermon in the Presbyterian
Church in Dayton. He is buried in Woodlawn Cemetery, Dayton where
his gravestone is inscribed:
‘To the Memory of the Rev. L.L.Langstroth, “Father
of American Beekeeping,” by his affectionate beneficiaries
who, in the remembrance of the services rendered by his persistent
and painstaking observations and experiments with the honeybee,
his improvements in the hive, and the literary ability shown
in the first scientific and popular book on the subject of
beekeeping in the Unites States gratefully erect this monument’

Bees by Ship
In a previous issue of Apis-UK we
reported on the movement of bees from the UK to New
Zealand by the Rev WC Cotton. Unfortunately Cotton left
no notes on how the bees fared whilst on ship an indeed we learn that they
may have had to have been thrown overboard. In this article however sent
to us by Trevor Weatherhead, we learn much more about the bees on board
ship. Trevor is the author of ‘Boxes to Bar Hives’,
a beekeeping history of Queensland which
was published in 1986. (Ed).
In the Australian Bee Bulletin of 23 September, 1893, is an article by
Angus Mackay who was an Instructor in Agriculture in the Technical College
in New South Wales. He was also at one time Editor of the Town and Country
Journal. The following is his account of bringing Ligurian bees from America.
“In 1877, it was my good fortune to bring from California the first
lot of Ligurian bees, so far as I know, that have reached this section of
Australia. I got them from Harbison, of the Santa Clara Valley ! They were
in a Harbison hive, about 20” square at sides and about 3½ feet
high. There were millions in it! The Pacific Mail Company very considerably
gave me the use of a cabin forward on deck of the fine ship City of New York.
Captain Cobb, a grand old American salt, was in command. We had heavy, muggy,
hot weather, after leaving the America coast.
The bees suffered fearfully. During several days I took out fully a ¼ of
them daily, assuming they would all perish, as 3 or 4 previous lots sent out
as freight had done. I got up early in the morning, very early, before daybreak
and edged the big hive out on deck, to give the bees air. The sailors noted
quietly what I was about, but said little. But the news spread, and was noted
that some of the passengers located where the bees were, and I was asked if
anything serious would happen to the ship if they got loose! If they would
slaughter all hands! Captain Cobb somehow, was interviewed, and with his first
officer he came to see about it.
“It’s a big, big job you’ve on hand,” he said. “I
hope it’s alright and there’s no fear of a rampage from them insects,
as you say. It’s the first time, though, I’ve run such a livestock
farm on this ship, and I do hope nobody will get hurt. Though some of the
folks are mighty scared. I tell you that’s so.”
The poor bees were having a fearful time. It’s really a cruel procedure
sending or taking them on a big journey. They suffer so badly from want of
water and from their dead. It was then I learnt how short is bee life, and
how confinement kills them. I made a cage promenade for them by wiring in
the top, and it was a sight to see the little maiden workers come up in the
mornings and drink the water sprinkled on them. The weather was hot as we
approached the Sandwich Islands, and the bees able to come up, soon as drops
of water are sprinkled on them, ran below the God given fluid to the suffering
hosts. From under the cage attached to the bottom board in the hive I took
away the dead and dying several times daily, as the workers carried them out.
Interest soon began to be taken by the ships company in the bees, and some
days before reaching Honolulu ring bolts were fixed in various parts of the
deck for fastening the hive in favourable places for air and shade, and the
livestock had become the biggest attraction on the ship. Even the Chief Engineer,
who for a time had doubts on the subject, became convinced that, should a
lot of bees get loose at any time, they would not make the engine room and
machinery room first thing!
Captain Cobb was a man; his first officer, engineer, cabin room bosun were
men also. To this day I believe it was arranged amongst them to reach Honolulu
at daybreak, and leave before nightfall, to give the bees a chance. Perhaps
the ship might have got in during the night, and left the next day. The City
of New York was tied up at the wharf about 4.30am. The bees were then located
up on the promenade deck. I knew the ship would not leave till after nightfall.
The bees were let loose! Poor things! Thousands of them had been born at sea,
and they fell sprawling on the deck in masses, ejecting matter which their
bodies were gored, for want of exercise. But, within a half hour of arrival,
they were streaming back to the hive loaded with pollen and honey! Very few
were picked up dead. After a short struggle for a few minutes, they got wing
and were off.
The town visited in Honolulu was a garden then! It may still be so still.
How the bees worked that day! I tried to keep the proceedings as quiet as
possible, and comparatively few knew of the livestock farm on the upper deck.
I was asked seriously, “Now are these bees likely to come off from such
a glorious shore, and into the box again at night? They look as though they
had more sense.” Well, by the time the word “Let’s go!” was
given it was dark then. I do not think there was an absent bee that was able
to fly back. The good old City got all her passengers that trip.
The remainder of the voyage was easier upon the livestock. They had a spell
in Sydney of a week, and landed safely in Brisbane. What a delighted man
was Jas Carroll to get the first lot of Ligurian bees, and the bees were then
as full, to all appearance, as when Bee Master Harbison put them up.”
In this fairly wide ranging review, John
Yates takes a look at the state of ‘the bee’ in the UK at
the moment.
All is not sweet and honey
In the early part of the
last century the majority of colonies in the UK were decimated by the
Isle of Wight disease now called Acarine. It was wrongly diagnosed,
according to Dr. Bailey who suggested that the colonies died out due
to viral infections. The situation was so dire that the Ministry of
Agriculture, or whatever it was called in those far off days, realised
the importance of honeybees for pollination purposes and set up a scheme
to subsidise beekeepers to import bees into the UK. The races of bees
came from all over Europe and a nation of mongrels was born.
It is now well known that there is no pure race of bee in the UK and
the whole population is one of mongrels derived from many pure races,
inter-breeding by natural means. Such natural selection favours the
ultimate survival of the bee in its particular environment accompanied
by a loss in heterosis and vitality. Nowhere in the country, except
in a few isolated instances, is there any attempt to eliminate bad tempered
bees which is in so much evidence today. BIBBA, The Bee Improvement
and Bee Breeders Association, formerly The British Isles Bee Breeders
Association (same acronym) has been endeavouring, over many years, to
engineer the renaissance of the Old English Bee with little apparent
success. Perhaps the most doubtful part of the breeding programme is
the small number of colonies of these bees which eventually must lead
to inbreeding which is denied by many proponents of the BIBBA objectives.
A few individuals bring in New Zealand queen bees for breeding purposes
and sell a first cross mated with the local riff-raff of drones; mostly
they are satisfactory queens but are useless for further breeding by
crossing with the mongrel drones. We know of Carniolan queens being
available as a private venture and also the Buckfast strain imported
from Scandinavia but overall it makes little impression on improving
the strain of bee in the UK. Bro.Adam, who died in 1996, stated that
the bees at Buckfast Abbey 80 years ago (ie. about 1920) were positively
ferocious compared to the Abbey bees of today. He also stated that swarming
and bad temper should have no place in the modern apiary devoted to
honey production. Unfortunately bad temper leads to leave alone beekeeping
and hence to swarming thereby propagating both undesirable traits. The
picture is one of considerable gloom. I wrote some years ago that one
can only hope that it will improve as a result of the incompetent beekeepers
giving up due to Varroosis leaving an elite who may put things right.
This is not proving to be correct.
"To keep a stock of honeybees pure is beyond the capabilities
of most beekeepers", stated H.H.Laidaw Jr. in 1979 when he published
'Contemporary Queen Rearing'; the position today remains much the same.
In the United Kingdom 95% of beekeepers are hobbyists and this could
be true in many other countries of the world. It is necessary to maintain
hundreds of colonies to select successfully the genetic material for
raising new queens and drones to mate with them. The hobbyist beekeeper
generally owns and manages no more than 20 stocks and this is insufficient
for producing consistent quality queens with known characteristics.
Taking a closer look at the United Kingdom, the economics of beekeeping
do not permit a living to be made unless the enterprise is augmented
with another sideline activity. In a commercial undertaking, the work
involved managing the large number of stocks required for honey production
is so great that many do not have time to rear queens and have to resort
to crude methods of swarm control or use no control at all, allowing
colonies to requeen naturally by swarming or supersedure. This is not
meant to be a criticism of these commercial bee farmers, they have to
resort to all sorts of short cuts in order to survive and most of them
would agree that were the economics different they would manage their
bees differently.
Years ago, when labour costs were low compared with equipment costs,
these bee farmers augmented their income by rearing and supplying queens
to the hobbyist beekeeper in addition to those queens required for their
own needs. Sadly the days are gone when it was possible to buy a queen
in the UK or from abroad with reliable characteristics (virgins at 1
shilling, mated at 1 shilling and six pence and a mated and tested queen
for 2 shillings and sixpence). Nowadays labour costs predominate in
all aspects of life. The reduction in the number of commercial bee farmers
rearing queens in large numbers for sale, or in many cases for their
own use, has materially affected the quality of the strains of bee in
the United Kingdom. It will therefore be apparent that we have reached
the stage where the hobbyist cannot rely on the queens offered for sale
and hasn't material of his own to improve his strain in a short timescale.
This has been a gradual process with the strains of bee becoming progressively
worse. This deterioration in the quality of our bees has been blamed
(by BIBBA) on the import of foreign strains crossing with our original
Old English Bee; it will be clear that this is not the complete story.
Strains of honeybee if left to their own devices eventually will never
produce massive crops of honey. For good crops, superior pollination
services, good temper, etc. it is necessary to breed in order to produce
progeny with these desirable characteristics. It has been done in other
aspects of animal husbandry and with plants; bees are no different.
The only bee breeding programme of any stature must be that left by
Bro.Adam breeding the Buckfast Bee which was a lifetime work introducing
gradually over a long period all the little refinements which make the
bee we know today. No one else has achieved the equivalent of his work
and, unfortunately, it now appears that his secrets went with him to
the grave.
There have been instances where the strain of bee has been changed
on a national basis and the two shining examples of this are Israel
and Germany where it has taken a considerable number of years. Israel
changed from the Apis mellifera syriaca to the Apis mellifera
ligustica and only achieved this completely when the feral colonies
of Syrian bees died out due to Varroosis. Germany changed from Apis
mellifera mongrels to Apis mellifera carnica. Both programmes
involved a detailed introduction system which was thoroughly planned
and on a very large scale. Government organisation and funding were
necessary to achieve success; a fact that is continually overlooked
by BIBBA probably because of DEFRA’s pathetic track record in
recent times ranging from the varroa debacle and on to that more recently
of foot and mouth disease.
The cataclysmic change was in Brazil and other countries as a result
of an experiment going wrong and ending up with the AHB (Africanised
Honey Bee).
Where does this leave the average beekeeper in the UK? On his own
and up the creek must be the only conclusion one can draw. However,
he still has his paddle and it is possible to produce a low swarming
bee of good temper by simple kitchen technology. Cull the bad tempered
queens and rear from the best colonies. We know it works as we have
done it for many years. The real problem is the vast majority of beekeepers
who will not bother to try but now there is one overwhelming problem
and that is Varroosis.
DEFRA and its national bee unit are banging on about IPM (integrated
pest management) which among other things includes destroying drone
brood. I said this was madness some 8 or 10 years ago on the basis that
the energies of the colony would be wasted. Unfortunately, those that
postulate these theories do not think them through sufficiently. We
now have a situation where it very difficult to get virgin queens mated
due to the shortage of drones which I attribute directly to the destruction
of drone brood as a method of varroa control. Remove large slabs of
drone brood and varroa mites will inhabit every remaining drone cell
in the colony; the drones that do actually survive are not much use
for queen mating because they are physically small and inferior on the
wing. I am not alone in noting this phenomenon; Paterson in Sussex recently
wrote on much the same lines.
There is slight evidence that some bees are resistant naturally to
varroa. We have two colonies in one of our apiaries which are grossly
bad tempered and the only reason we allow them to persist is that they
could have a natural resistance to varroa. We have no intention of breeding
from them because of their poor behaviour. The outlook seems to be very
gloomy and there are indications that it will get very much worse before
it gets better. Apis-UK could start an interesting survey asking beekeepers
how many virgins they managed to get successfully mated this year. Last
year all ours turned out to be drone layers. Results in the October
or November issue. How about that Ed? JDY. April 2005.
I think we may take you up on that John for the next issue.
On the subject of removing drone brood, I have always regarded this
as a dangerous move. Surely the internal dynamic of the hive must
in some way be disturbed by this. I haven’t seen any research
on it so if anyone out there has, please let us know. Ed.
Soon we will be converging on Ireland for the World jamboree of beekeeping,
Apimomdia 2005 and so it is appropriate that we include in this issue
news of Irish beekeepers. It is always a pleasure to receive interesting
articles about what beekeeping groups get up to and we invite anyone
to send us an idea of what your association does in words and pictures.

The Dublin Study Group’s queen rearing diary
By
Eamon Magee, Joe Kelly, Liam McGarry and Simon Rees
Introduction
We
four are a study group for the FIBKA Senior exams and have chosen to
rear queen as a co-operative group. We decided to choose the apiary
of Eamon Magee in Derrybawn as the location, as it has strong stocks,
plenty of space and a building with spare equipment etc, nearby.
7th
May: selection of breeder / cell raiser colony
Colony no.5 at
Derrybawn was chosen as the best breeding stock because of good showing
in the colony records and because it has a Mac Giolla Coda queen.
21st May: put Cupularve kit into breeder colony
We
met at Derrybawn to insert the Cupularve kit into the breeder colony.
We discovered that the breeder colony had swarmed, and so chose a different
colony (no. 4) as breeder / cell raiser.
While 2
of us inspected the colony and found the queen, marked bright yellow, the
other 2 attached the Cupularve to a brood frame.
We inserted the frame with the Cupularve kit into the hive in order
that it acquire the colony (or, according to Bro. Adam, hive) odour.
We took
the opportunity to harvest a queen cell from the swarmed colony and
to insert it in an Apidea box with a scoopful of bees. Simon will
use this F1 Mac Giolla Coda descendent in another colony.
Update Oct 04: This queen mated successfully in her Apidea mini-nuc box
then absconded into a bait hive on the garage roof - see below. The colony
is now fully established.
29th May: Queen confined to Cupularve
In the morning
we inspected the colony again, found the queen, and confined her to
the Cupularve. In the picture below the queen (marked yellow) can be
clearly seen confined to the Cupularve.
That evening we checked the colony to ensure that all was well with
the queen. She was settled in the kit and accompanied by workers.
30th May: Transfer eggs onto cell bars
The big day.
We saw to our delight that the queen had laid eggs in the Cupularve
cells. An egg can be seen in the middle of the cup pictured below.
Each charged cup was gently removed from the Cupularve frame and fixed
to a cell cap cup.
Each of these is in turn fixed to a cell bar fixture (dark brown,
below) that has been nailed to the cell bar (see picture below). We
transferred twenty charged cells to the cell bars prepared earlier
(see picture) and inserted them into a brood box above the queen excluder,
which had been prepared for this purpose. The queen was released – gently – and
the Cupularve removed and packed away.
2nd June: check progress
Eamon
checked on the progress of the queen cell building and larva feeding.
As you can see from the picture here, wax building has begun.
9th June: distribute queen cells
We met at Derrybawn with Apidea boxes
charged with grumpy bees all ready to receive the queen cells. We ended up
with eight viable – looking
cells, which we distributed into the Apidea boxes.
Early July: progress report
This mini-nuc is doing
well – as you can see below, the bees
have built comb. She’s laying well and ready to be united with
a queenless colony. This mini-nuc is not one of the standard Apidea
types that you can see in the picture above, but it seems to work well.
October: final update
Our queen rearing efforts have
yielded about half a dozen mated queens (Eamon reports that one virgin
queen was mistreated in its nuc and had to be fostered in an Apidea,
where she thrived).. We've also acquired a heck of a lot of learning!

Heated Water Drinking Station
at Home Apiary
Gregory Boon www.wholesomehoney.co.uk
I keep my bees in ancient WBC hives, bought from Wilfred Stanbridge,
a semi-commercial beekeeper who used to have over a hundred of them,
all filled with quite aggressive bees. I always have something on which
to place the supers while I look at the bees and I don't lose queen-right
colonies in the winter; I've always thought that this must be due to
the extra insulation and dryness. The brood chambers are too small though.
At Stoneleigh this year I was told that 80% of continental hives use
polystyrene, and the extra insulating effect really helps the bees (ok,
so I was told it by someone selling them, but as they also have 2000
hives, they should know what they're talking about).
I really hated seeing dead water gatherers and so I made this little drinking
trough. The pipe is connected to a hot water tap. It spirals to the centre
under the mossy bricks. No more dead bees, at least at water source, maybe
not all of them make it back to the hives, but their chances are greatly
enhanced on those cold spring days when the colony must have water.
RECIPE OF THE MONTH Back
to Top
This is a recipe used by the ancient Maya civilisation of Central America.
Honey and bees (stingless) were central to Mayan life; indeed, the Mayan people
called themselves the people of the land and the bee. Bees were messengers
of the gods and were revered. Stingless bee honey was used in ritual, as a
drink and as a medicine. Its medicinal properties have never been fully investigated
and herein may lie a great future for this declining type of production. When
the European bee arrived Mayan authors likened the decline of their own type
of beekeeping to the decline of their people in the face of the sting and
industry of the white man’s bee and the sting of the white man’s
sword. In this recipe you can use ordinary honey. For some of you in Australia
where stingless beekeeping appears to be enjoying a renaissance, try using
the real thing!
Pumpkin Soup
In early pumpkin soup recipes, the pumpkin would have been baked whole in
hot ashes. Peeled and chopped pumpkin would then have been thinned with broth
from wildfowl or game.
1 small pumpkin, about 12".
2 tbs palm oil.
3 tbs honey.
1/2 tsp ground allspice.
4 c turkey broth.
Salt to taste.
Thinly sliced wild onions.
Roasted pumpkin seeds, for garnish.
Preheat oven to 350 degrees. Place pumpkin in a baking dish and roast until
easily pierced with a knife, about 1 hour. Allow pumpkin to cool, slice off
top and scoop out seeds. Clean pumpkin fibers from seeds and discard. Toss
seeds with oil and salt to taste. Spread out on a baking sheet and return
to oven 15-20 minutes, until crisp and golden. Reserve for garnish. Scrape
the pumpkin flesh from shell and mash, or puree if a smoother mixture is desired.
Place the pumpkin in a large saucepan and season with salt, honey and allspice.
Gradually stir in enough broth to make soup with thin or thick consistency,
as desired. Simmer over medium heat about 5 minutes, until hot. If desired,
serve soup in small pumpkin or squash shells. Garnish with onions and pumpkin
seeds.
FACT
FILE Back

KASHMIR BEE VIRUS (KBV)
Last year we reported on the investigation undertaken by
the UK National Bee Unit into viral infections in honey bees.
The study used the TaqMan PCR technique. This is a molecular
based diagnostic technology often used for the detection of
plant health pests and pathogens, but in this study used exclusively
on honey bees.
Of 458 colonies tested, three proved positive for KBV. As
you read in the news section, all the colonies appeared normal
for the time of year and the results indicated that the virus
is likely to have been present for some time and not related
to imports or migratory beekeeping. CSL say that the results
tend to confirm what they have considered a possibility for
many years that KBV is not necessarily an exotic bee virus.
Within Europe findings have been reported in Spain, Germany
and France. So what exactly is this KBV.
KBV is a natural disease of the eastern honey bee Apis cerana.
When Apis mellifera was introduced to the area, the virus jumped
over and began to parasitise its new host. For the technically
minded it is an RNA virus in the family Dicistroviridae. These
RNA viruses are small in comparison to DNA viruses and are
associated with the mitochondria of host cells.
KBV’s virulence is made possible by the association
with varroa mites. Mites carry the virus internally and externally
and can spread the virus not only from mite to bee but also
from mite to mite. By piercing the bees cuticle, they transfer
viral particles into the host’s tissue. The pupal stage
seems to be the most vulnerable to infection.
The causes that trigger virulence are still not fully understood.
During the 80s in Canada, the presence of KBV in colonies was ‘an
academic curiosity’ and virulence may only be caused
by a high number of virus carrying varroa mites, causing stress
and an increased vulnerability, but other studies have found
that KBV virulence can also occur when varroa infestation is
low.
Symptoms
Few if any in the field. Laboratory
diagnosis is required. Unexplained weakening of the colony
may be a sign, as would signs similar to virus paralysis disease – dark
hairless bees; uncoordinated bees; dead and dying bees on the
alighting board and inner cover; bees with a dark and greasy
appearance. Be careful however, the only real test is the lab.
Treatment
There is no treatment. The best way
to prevent an occurrence is to keep varroa well under control;
i.e., control the vector and keep mite levels below damage thresholds.
In common with many bee ailments, if you run your apiary
well, keep a tight grip on varroa and ensure that your bees
are not stressed, the chances of your bees suffering from KBV
will be reduced.
I have kept bees in Spain for
many years and have never noticed this problem. To be quite
honest, I never really thought about it. Perhaps it has been
around for many years and has only now been discovered because
of improved detection techniques. If you want to know more,
you can find information on the NBU website www.nationalbeeunit.com Ed).
HISTORICAL
NOTE Back to top
The uses of wax and honey have always been of interest to beekeepers
and The Rev WC Cotton writing in the 1840s in his manual
for New Zealand Beekeepers gave some advice on the use of wax as
a medicinal substance. The book was published in Wellington in
1848 after Cotton’s return to the UK and was found of great
value in the rough and primitive conditions of the very young colony.
‘…But there are many smaller articles that the
careful housekeeper will like to have at hand. Lip salve and
cerate are no bad thing to have in the house; the latter is
made by heating an ounce of wax and heating an ounce of sweet
oil, not boiling either. Pour them together at about the same
temperature, and keep stirring steadily until they leave the
fluid for the buttery state. If you leave off stirring just
at the setting point, the wax and oil will separate and you
will have to melt again. But if you stir steadily all the time,
you will have a substance as soft as butter and as smooth as
oil; of such excellent healing powers, that I have sometimes
wished to have a sore place to test its virtues. The cerate
may be made harder or softer by altering the proportion of
oil to the wax.’
POEM OF THE MONTH Back
to top
This month’s poem comes from that marvellous American
poet of the 1800s, Emily Dickinson. (1830 – 1886). The
vast majority of Emily’s poems were rejected by publishers
during her life time and in common with many artists, only
after her death did her true worth become known. She had written
over 1700 poems.
Pedigree
The pedigree of honey
Does not concern the bee;
A clover, anytime to him
Is aristocracy.

Dear Mr. Cramp,
My brother, who lives in Ohio,
USA, is the owner of two volumes of the books "Beekeeping
New and Old" by W. Herrod

signed by the author, the second volume is unsigned. He bought
them a number of years ago from another beekeeper, who now is
quite insistent about wanting them back. I have done searches
on Amazon used books and on Book Finders and come up with nothing.
In you capacity as editor at BeeData have you any idea where
on might find information on these books. A Google got two hits

Tuesday 26th, Wednesday 27th and Thursday
28th July - Bees & Honey
at the New Forest & Hampshire County Show is held at
New Park, Brockenhurst. Preparations for the Honey and Bee Marquee
are in full swing with the schedule for classes now available. The
New Forest & Hampshire
County Show holds a large open honey show and welcomes competitors
from across the country, with a variety of 30 classes to choose from
in the large honey and bee marquee. Expertise is not necessary to
enter, just enthusiasm for the craft. The Show is a charity, whose
purpose is to support countryside activities and try to ensure that
our rural heritage is protected. As a result of this all the marquees
run by the Show have a theme that is provided to hopefully educate
the public in an entertaining way. The Honey and Bee marquee fulfils
this by having not only a whole range of activities for children,
including beeswax candle making, demonstrations of live bees and
a glass wall observation hive; but for those interested in the history
of honey-making and the lifecycle of the bee there are knowledgeable
enthusiasts on hand with microscopes, display cabinets and literature.
Honey tasting is a popular pastime during the Show and bee keepers
who exhibit can sell their wares to the 100,000 visitors the Show
attracts.
For details of the schedule or any other enquiries please
contact the Chairman of the Honey and Bees Section, Margaret Davies
on 01202 526077 or by E-mail on marg @ jdavies.freeserve.co.uk.
Tickets for the Show will be available from June 1 st on the Show’s

QUOTE OF THE MONTH Back
to top
Quote last month
The quote for last month of course came from Francoise
Huber the blind Swiss scientist who with the aid of his servant Bernand
and wife Maria, managed to find so much out about the honey bee that
our knowledge of this creature advanced immensely.
Quote of this month
There have been many descriptions of honey bees. This one
comes from a well know book and I have no doubt that many beekeepers
will know the source of this quote:
‘The bee is small among the
fowles, yet doth its fruite passe in sweetnesse.’
