1.      Editor's Notes

I spoke too soon in the last Newsletter. Instead of the final arrival of spring we have experienced, apart from a few days respite, a return to the low temperatures and biting winds of the winter. This poses a problem, which is what to do about helping the bees get through this extended cold patch. When the weather has briefly relented, the bees have immediately started flying and have been bringing in pollen. The queen will have been stimulated into laying but there is as yet no nectar flow to help with the feeding of any hatching pupae. While I have made sure that there is some sugar available to prevent starvation, I think that the bees now will need more than that. Accordingly I am starting to give them a 1:1 syrup feed with the expectation that it will help with colony development, which might otherwise be impeded.

Part of my thinking is that I want a vigorous colony ready for the flowering of the oilseed rape that has been planted in the fields nearby. The last time it was grown on these fields the bees missed out because flowering coincided with a bout of cold wet weather. This year, so far, growth has been very slow and there is no sign yet that that is about to change. I have read recently that some farmers are ploughing their oilseed plants back into the ground because they now have little chance of maturing properly. As beekeepers we must be eternally optimistic but there are times when that is very hard.

Elsewhere in this Newsletter I have included an article about the Bailey Comb Change. This is designed to give the bees a fresh start on a full brood chamber of new comb but without the ‘trauma’ of the shook swarm. If the rape doesn’t materialise I can use the vigour of the developing colony to carry out this manipulation instead, which will stand them in good stead for the rest of the season.

 

2.      Association Meetings

For our March meeting we once again hosted Celia Davis from Warwickshire. This year her theme was ‘Keeping on top of Varroa” and about 50 members were given a comprehensive account of the mite and the options for dealing with it. After a brief description of its physical appearance and the history of its gradual encroachment into Europe from the east, Celia focused on its life-cycle and the clues that that might contain as to effective intervention. The threats from varroa come from two directions. By feeding on the bees it directly shortens their lives and thus weakens the colony. This process is then greatly aggravated by making the bees more susceptible to the many viruses that they are prey to, including deformed wing virus, slow paralysis virus, acute paralysis virus, Israeli/Kashmir virus, sacbrood virus and so on.

Clearly we cannot ignore varroa because it will kill off colonies if not dealt with. While total elimination is unrealistic, varroa can be managed so as to keep it at sub-lethal levels. Celia talked about the history of treatments, including Bayvarol & Apistan, which were very effective when they first appeared but are now unreliable, as the mites have developed resistance to the synthetic pyrethroids they contain. She referred to the thymol based treatments such as Apiguard and ApiLifeVar. Oxalic acid got a mention as a ‘hive cleaner’ but other possible treatments such as formic or lactic acids were not included. However, attention was drawn to the less invasive techniques that can be very effective in controlling mite numbers if used regularly, such as mesh floors, icing sugar dusting, drone-brood culling and use of the shook swarm technique. Trapping the queen on a drawn frame so as to ensure that all varroa mites could be removed over a three-week period was explained in some detail. This is quite drastic as it means losing three weeks production of eggs/larvae but will clean up a badly infested colony that might otherwise succumb. As always, Celia gave us excellent ‘value for money’, and hopefully renewed our determination to do even better this season.

(* A detailed account of the queen trapping technique will appear in a future Newsletter -Ed.)

The next meeting is on Saturday April 10th and is the first of this season’s apiary meetings. It will be at Radbrook commencing 2.30 p.m. and will focus on ‘Starting the Season’.

The last of the indoor meetings for the time being will be on Wednesday 14th April, at Shirehall, beginning at 7.30 p.m. Geoff Critchley will advise us on “What to do or not to do on discovering a queen cell” in a talk called “Cut it Out?”

 

3.      2009 Queen Bee Imports

Taunton & District Beekeepers Newsletter reported that their Bee Inspector had provided the following figures for the KNOWN import of queens to this country in 2009.

From Europe
Greece 2085
Cyprus 778
Slovenia 2034
Italy 375
Austria 8
Poland 128
Denmark 44
Germany 113
Total 5565

From the Rest of World
Australia 30
Hawaii 4182
New Zealand 740
Total 5222

This produces a grand total of 10,787

The editor commented: I find this figure quite staggering when we are warned of the possibility of exotic species coming into the UK.

4.      New Farming Protocol Includes Beehives

Bird populations will enjoy a 33% boost in food supplies on some British farms next winter following a revision of Conservation Grade’s farming protocol, which enhances a range of animal and plant life by turning 10% of viable farming area into wildlife habitats. The protocol, which is the only one in the UK specifically designed to increase critical biodiverse species while focusing on efficient crop production in the other 90% of the land, is increasing the areas required to be sown with wild bird seed mixes such as cereals, quinoa, sunflower and millet, from 1.5% to 2%. It is also newly supporting the introduction of beehives on all its farms as a ’desirable option’, to go with the existing requirement for owl and bat boxes.

The wild bird mixes produce seed during the winter to provide food for birds such as the yellowhammer, linnet and corn bunting. Brin Hughes, agri-environment advisor with Conservation Grade, explained that "The new recommendation to include beehives is simply providing further opportunities for bees to utilise the food supplies from the wild flower and legume habitats required by the protocol."

5.     The Bailey Comb Change - replacing old brood comb

We are advised that old brood combs should be changed regularly as they become damaged, contain excessive amounts of drone comb, but mainly because they may contain the causative organisms of bee diseases, especially foul brood and Nosema. No brood comb should be used for more than 3 years and used comb should be rendered or burnt. Ideally these frames should be replaced with drawn comb but, if foundation is used, the bees will need to be fed with syrup in the absence of a nectar flow at this time of year. However, it seems more sensible to me to do a complete change so that all (possibly) diseased, deformed and grotty frames are changed at the same time. This can be achieved by doing a shook swarm, but this seems unnecessarily disruptive in the absence of proven European Foul Brood. An alternative is the Bailey Comb Exchange.

How to do it? There is an account in February BBKA News p 4, but it is unnecessarily complicated. Here is a simpler version which works. It can be performed between March and June, but the earlier the better. Prepare a clean brood chamber filled with frames of foundation, using narrow spacing, and place it over the existing brood chamber. Unless there is a strong nectar flow on, feed with thick syrup (1kg of white sugar to half litre water). When the bees have drawn some of the foundation, find the queen and place her on this comb, putting a queen excluder between the old and new brood chambers, thus trapping the queen in the top new one. Keep feeding, so that the bees continue to draw the foundation. After three weeks, when all the brood in the old brood chamber will have emerged, the old chamber is removed and the new one is placed on the floor with the queen excluder above ready for supering The old comb should be rendered or burnt.

NB Foundation should be fresh as, when old it becomes brittle and the bees are reluctant to draw it out, preferring to chew holes in it! Old foundation can be restored in part by warming, in the airing cupboard for instance, which releases the oils.

Combs at the ends of the brood box tend not to be well drawn especially on the outer face, as the bees cannot cluster there to make wax. Turn it around and/or move it nearer to the brood nest.

6.     "Explosive" Honey

Authorities shut down a California airport on Tuesday after a suspicious amber liquid in a passenger's bag tested positive for explosives -- only to ultimately determine that the substance was honey. Francisco Ramirez, a 31-year-old gardener who had been visiting family in the central California city of Bakersfield, was allowed to return home to Milwaukee. "The substances in the bottles did turn out to be honey. They tested negative for all explosives and narcotics. It is nothing but honey," FBI spokesman Steve Dupre told Reuters. The security scare came as jitters gripped the U.S. travel industry in the aftermath of an unsuccessful Christmas Day attempt to blow up a Detroit-bound commercial flight.

Meadows Field Airport in Bakersfield, about 100 miles north of Los Angeles, was shut down and evacuated for hours and flights diverted after the incident, which began when Ramirez' bag set off an alarm in a luggage screening machine. U.S. Transportation and Security administration screeners turned up five Gatorade bottles full of what they called a "suspicious-looking liquid." Swabs of the bag and bottles tested positive for the explosives TNT and TATP. When the bottles were opened, two of the screeners smelled a strong chemical odour, complained of nausea and were rushed to a local hospital, where they were treated and released, Kern County Sheriff's spokesman Michael Whorf said. Kern County Sheriffs’ deputies, fire crews, FBI agents and members of a "joint terrorism task force" responded to the scene and spent the day questioning Ramirez before further tests showed that the liquid was honey.

After the all clear was given, officials said they were trying to determine why the honey tested positive for explosives and made the screeners so ill that they would need medical attention. "There are some questions I think are going to have to be followed up on," Dupre said.

7.      TED HOOPER MBE NDB. (1918 – 2010)

A message from Geoff Mills, Hon. Life Member, Essex BKA

It is with great sadness that I have to inform you that Ted passed away in hospital last Friday. Ted was born in Devon over 90 years ago and spent most of his lifetime working with bees and instructing others in the art of beekeeping. He was the County Beekeeping Instructor for Essex for over twenty years, was Chairman of the National Diploma in Beekeeping and Chairman of the BBKA Examination board for many years. In 1976 his book “A Guide to Bees and Honey” was published and it became the “Bible” of many beekeepers throughout Britain and the world. It has been translated into over twelve languages and has sold over 100,000 copies worldwide.

Ted will be sorely missed and our condolences and good wishes go to his wife Joy and their family.

 

8.      News Items

Reports of Thefts
Already this season there have been several reports of thefts of colonies of bees from various places around the country. The relative scarcity of honeybees has put up the price of buying them quite considerably. Sadly there are always those who would try to make an illegal profit from this situation. Although some reports of unsuccessful attempts to remove hives have suggested that the thieves have not known what they were taking on, others suggest that experienced beekeepers were involved. Keep an eye on your own hives. If they are in an out apiary, you are advised to brand all your hive parts so that they can be readily identified. At all times keep an eye open for suspicious activity and report any concerns to the police immediately.

Adopt a Beehive
The British Beekeepers Association has announced its response to the widespread public concern over the country’s disappearing honey bees, by launching Adopt a Beehive – the first public fundraising campaign in its 136-year history. Sponsored by the Saga Group and supported also by Michelin-starred chef Raymond Blanc, the new campaign is aimed at the many thousands of people who are concerned over the appalling loss of honey bees but who are unable to have a hive themselves.
Andrew Goodsell, the Executive Chairman of Saga, said, ”I am delighted that Saga has been able to help create the Adopt a Beehive campaign. Many people are deeply concerned about the environmental and other problems facing the honey bee. This scheme enables people who do not have time to keep bees personally to play an active part in helping to saving the British bee.”
To Adopt a Beehive for a year costs £29.50 and each person will receive a welcome pack including a jar of British honey or a jar of honey mustard, a fridge magnet, a wooden honey dipper, postcards, facts sheet and certificate. The seasonal newsletter will provide a link to the hives of a network of beekeepers from around the UK and the latest news of bee health research.
For further details, and to sign up for Adopt a Beehive visit this website and meet the colony of 14 beekeepers whose progress can be followed online.
