LOCAL BEE INITIATIVE
As a new initiative for 2021, SDBKA is supporting BIBBA's National Bee Improvement Plan (actually in a slightly stronger form). The simple message is "please do not import bees" into our Salisbury area, but instead use locally-raised bees. There are a number of positive reasons why this is strongly advisable, and also reasons why importing bees and most purchases from commercial suppliers are damaging:
Since at least the last ice age, about 10,000 years ago, the European honey bee Apis mellifera has been evolving to adapt to local conditions. This has resulted in different subspecies native to and adapted to the conditions in different parts of Europe, with Apis mellifera mellifera the native bee in northern Europe, including the UK and Ireland. Imports of bees over the last 100-150 years have been considerable, with over 20,000 queens imported into the UK this year from the EU alone — almost all of which are not of our native, adapted bee.
Bees have reproductive behaviour which causes their genes to spread over a distance. A queen typically mates with 10–20 drones, and can mate with drones from colonies over 9mi distant and is likely to mate with at least one drone from a colony half this distance away. From this we can see one beekeeper's bees are likely to affect the genetics of every other colony within a few miles whenver it requeens by open mating.
Commercial producers typically don't supply bees that are locally adapted, and often not even of a stable strain. It is well known that Buckfast bees, a hybrid of subspecies, are docile and productive initially, but their temperament one generation later after open-mating is typically much poorer, and often unworkable a generation later. This is due to heterozygosity when interbreeding with local drones. Some beekeepers attempt to solve this for themselves by continually buying new queens, but this perpetuates the damage that their drones impact on characteristics of other local colonies as they requeen.
In addition, importing of bees to an area can present a biosecurity risk. Varroa was almost certainly introduced into the UK via imported bees.
A.m.m. genes are estimated now to represent about 40% of honey bee genes in the UK. Despite the large amount of hybridisation, particularly in much of England, fairly pure A.m.m. colonies are known to persist, particularly in the harsher climates of Wales, N England and Scotland and Ireland where they're better able to survive. This gives hope that if importation of bees stops then locally adapted, genetically stable populations can establish themselves again, and the heritage of these native bees preserved.
With a stable population of bees in our area, undisturbed by continual imports of bees with non-local adaptations, it should become easier for beekeepers to select for desirable characteristics, such as good temper or varroa resistance, within the local strain.
I hope you will agree that all of this is worth working for, and hope you will show your support by filling in the form here.
To help support this initiative, we are starting a programme to make Association-produced nucleus colonies of bees available to our members, and particularly to our new members. These will be colonies on 5 or 6 National-sized frames, either standard (14'' x 8.5'') or extra deep (14'' x 12''), and will be priced very competitively, essentially to cover costs. The queens that head them will have been raised and locally open-mated from colonies of known good temperament and with a number of generations of pedigree of local open mating. Usual good beekeeping practices mean that the colonies will have been monitored for varroa and other diseases. All of this makes them suitable for beginners in a way that swarms may not be: a swarm may harbour disease, and it may show very defensive behaviour. Members can sign up for these nuc colonies in the member pages here.
For more experienced beekeepers who want to increase the number of colonies they run, there really is no need to import or buy bees from outside our area. There are many options for making increase within your own apiary — such as the increase that naturally comes with managing swarming. The Association may be able to help with this too by providing queen cells for good local queens. Even if you have just bought a colony of bees, and now wish they were local bees instead, it's possible to requeen them with a local queen. Again, please see the member-only page here.
