Puttenham Common meeting Saturday 19th July at 2.30pm

Take a walk on the wildside to see some of Britain’s solitary bee species and other associated insects. Bee suits not required. The venue is Puttenham Common, which is outside our normal area but has the advantage of a large free car park and plenty of ragwort and heather flowers to attract bees. 

The venue is the Top Car Park (do not go to other car parks on the Common), off Suffield Lane, south of Puttenham village, GU3 1BE; What3words hazelnuts.title.year. There is usually a coffee stall in the car park, which will be the meeting point. No toilets. Bring refreshments for a social gathering after the meeting. 

If you are attending this meeting, you must let me know by emailing ahalstead44@btinternet.com If the weather forecast for Saturday is not good, the meeting will be postponed until the following day. If there is a large attendance it may be necessary to split the attendees into manageable sized groups for the guided tour.

This should be an unusual meeting of great interest, where we shall be introduced to bees other than our own with which they are said by some to be in competition – or are they? 

Are you familiar with Demaree hive manipulations? (George Demaree, 1832-1915) 

I first heard of this about 40 years ago as a method of Swarm Control. For some reason that has disappeared in the mists of my memory, I did not find it very successful. However, recently I have heard a number of beekeepers, new and old, quoting Demaree, so thought I had better re-acquaint myself with it, as some of what I have heard did not seem to tally with my faint recollections from the past. I found an excellent article by G.D. Morse in the Encyclopaedia of beekeeping (Roger Morse and Ted Hooper), but there are several others. My (hopefully) easy to follow presentation of this method follows: 

  • Move the brood box to one side 
  • Take a second empty brood box and put it in the position of the original brood box 
  • Find the queen and place her, on her frame, preferably with some eggs and unsealed brood in the second brood box 
  • Fill the queens’ box with frames containing foundation 
  • Put a queen excluder on the box containing the queen 
  • Place one or two supers on the queen excluder 
  • Place a second queen excluder on the top super 
  • Place the original brood box complete with the rest of the brood onto the second queen excluder, and add a frame to restore the full number of frames 
  • Destroy all of the queen cells in the top brood box 
  • After a week, check again and destroy any queen cells (if this is not done the colony may swarm) 
  • After another three weeks, the brood will have hatched out, and the box will act as a super 

It should be noted that there are many variations on this procedure, some of which seem to me to be not very easy to follow. A disadvantage of the method is that the hive can become very tall, and so the lifting of a heavy brood box through an uncomfortable height is involved, especially if it eventually becomes full of honey. 

Some beekeepers use Demaree, with some modifications, to raise queen cells and hence new queens. 

I must emphasise that this article is not intended to recommend or discourage the use of this manipulation. I just wanted to share some of my thoughts and knowledge of it. 

Norman Carreck’s Talk, The Future of Native Bees in Britain and Ireland, Didn’t Disappoint! 

Organised by the Croydon Division of the Surrey Beekeepers’ Association, the event was well attended, with an estimated 80 to 100 of us eagerly listening in. Before I go any further, I should emphasize that this report is neither peer-reviewed nor entirely accurate—just the enthusiastic recollections of a keen beekeeper who understood about 50% of the presentation but enjoyed the cakes and networking 100%! 

Following a lively introduction of the speaker, the audience settled in, relieved to have arrived at the correct venue (though I must admit, if not for the postcode, the rest of the address confused Google Maps more than it helped). One perk of the beekeeping community? It made me feel relatively young—even at 56! That said, we do need more beekeepers in their 20s and 30s. 

Norman’s main argument is that native bees—those indigenous to a specific geographical region rather than introduced by humans—tend to be more disease-resistant than imported ones. Two key graphs supported this claim: 

A study across 16 regions in Europe where 18 different bee strains were monitored over five years without varroa treatment. The survival rate was around 20% for native bees, compared to just 10% for non-native ones. 

A series of UK heatmaps from 2007 to 2021 showing shifting “hot zones” of disease outbreaks. The culprit is likely to be the importation of queens and colonies from abroad. 

While the natural spread of bees is limited by the distance drones can fly, a fascinating experiment on the Isles of Scilly demonstrated that, when lured by queen pheromones (and assisted by the wind), drones can travel farther than previously thought. 

One reason bee imports are increasing is that we’re not rearing enough queens domestically. Requeening hives is common practice, but in the UK, unpredictable weather often sabotages queen rearing. Norman joked that there are four reasons we struggle to raise queens: weather, weather, weather, and weather! When a newly raised queen is ready to mate, a cold spell or rain can ruin the entire process. It’s much easier (and more profitable) to rear queens in France, Spain, or Romania. 

Interestingly, statistics show that bee imports declined slightly post-Brexit—one rare silver lining of that self-inflicted arm! However, it turns out many imported bees now enter Britain via Ireland and Northern Ireland, bypassing direct restrictions. 

Not everyone agrees that preserving native bees is crucial. Personally, I do not feel like becoming an activist for the cause. Some argue that bees evolve naturally over time and that economic realities must be considered—after all, 900 professional beekeepers depend on imports to sustain their businesses. (Franck’s note) 

A prime example is the Buckfast bee, which isn’t native but is widely praised. Developed by Brother Adam in the early 20th century (in response to the Isle of Wight disease), Buckfast bees remain commercially popular today. However, Norman pointed out that despite claims of a consistent lineage, Buckfast bees now vary significantly in appearance and genetics. 

The Q&A session featured some highly technical discussions, much of which went over my head. Wanting to make Weybridge proud, I managed to ask a question—even if the only thing I have in common with Norman is that I started beekeeping 40 years ago! 

One thing I don’t share with Norman, however, is his enthusiasm for laser pointers. While his use of it was effective, I found myself getting dizzy watching the red dot dart across the slides like a fly trapped behind a window. 

Eventually, we moved on to networking, where the conversations were engaging, and the cakes were absolutely amazing (all for a small donation). I wish you had been there!

Talk by David Rudland: Varroa and other bee health problems in bee colonies, 24th March 

This talk by David Rudland is a regular feature in our Division’s yearly programme, mainly organised for our beginners’ group but to which all the members are invited. Although an annual event, this certainly does not mean that there is no need to attend it more than once: indeed, we all need to be reminded of the importance of revising our knowledge of the recognition of bee diseases and the ways to deal with them, before we have the misfortune of finding them in our own colonies. And it is very important to be reminded to be on the alert for them, and how to recognise them when they are in the colonies. So, it has to be said that that it was disappointing that so few of our members that came along to join our students to hear yet another excellent presentation. 

David began by telling us that he runs between 250 and 300 honey-producing colonies. He also produces nucleus colonies and queens. His other activities include the organisation and running of beekeeping and other related courses. 

He devoted the first half of his talk to dealing with what he described as our biggest problem as beekeepers, namely varroa. After describing its life-cycle, he went on to describe some of the damaging effects that varroa has on honeybee colonies: reduced body weight, smaller hypopharyngeal glands (resulting in a reduction of brood food production and hence impaired brood development), reduced wax production, shorter life span and eventual collapse of the colony. But perhaps the most serious is that they act as carriers of very many damaging viruses which seriously affect bees, perhaps the most serious being deformed wing virus). He drew our attention to the importance of monitoring the varroa levels in our hives, and be aware of the population levels at which controlling action should be taken. 

David went on to describe various chemical and non-chemical ways of controlling varroa, and emphasised the importance of being aware of the risk of breeding mites that are resistant to the chemicals that we use, due to their overuse. Beekeepers are obliged by law to keep a detailed record of any chemicals they use in their hives; in particular the batch number of the chemical. In his own apiaries he makes extensive use of the ‘Shook- Swarm’ method as an effective non-chemical way of controlling varroa. He stressed the need to include a frame of drawn comb when setting up a shook swarm operation to trap and destroy the mites that will be produced in the comb, with the queen in full lay. 

In the second part of his talk, David dealt particularly with AFB and EFB, these being the most serious diseases after varroa, and he emphasised the legal obligation of a beekeeper to report suspicion of this in a hive to the NBU via the local Bee Inspector. He outlined a number of less serious problems including chalk brood, ‘pepper pot brood’, bald brood resulting from wax moth larvae activities, although uncapping cells is currently thought to be bees learning to recognise varroa mites under capped brood, and uncapping them to stop the development of the mites. David stressed the importance of learning the appearance of healthy brood (sealed and unsealed) so that diseased brood can be easily recognised. 

We were grateful to David Rudland for another excellent presentation on very this important subject.
