Varroa Resistant Colonies
What's Happening in the Hive Now
It has been a strong spring flow this year in the southeast of England. The sun has brought out the best blossom I have seen in a few years and allowed the bees to forage away, filling supers and driving strong brood nests.
Nearly all my hives have now been split and I'm hoping that the queen mating will go a lot better than last year's rain-affected struggles. There are certainly a lot more drones flying, and of course I've been encouraging them in my varroa resistant colonies as I look to flood the area with the varroa resistant genetics.
In my varroa resistant hives, I was seeing uncapping and chewing out (as evidenced by exoskeleton parts on the insert board) right up until I harvested surplus queen cells and left the hive alone for a couple of weeks to let the one remaining hatch and get mated. During this three-week brood break (the old queens were split out with stores and capped brood as artificial swarms into nucs a week before the queen cell harvesting), there has been an inevitable pause in uncapping and exoskeleton parts are no longer visible on the insert boards.
Sometimes a strong flow can also stop uncapping as the bees focus on nectar and pollen processing, but I saw it all the way through this spring flow despite its strength.
The brood break in mite susceptible hives can also lead to a spike in varroa mite numbers on the insert boards. Not so in my varroa resistant hives, where numbers remain very low despite the break - fewer than one a day in some colonies and about one a day in others. Remember, uncapping and chewing out will lead to low mite drop numbers and a high proportion of those will be infertile.
Last month, I wrote about planning my bee breeding, ensuring that I'm proliferating my best varroa resistant bees and re-queening mite susceptible colonies. I'm well under way with that process, the weather allowing some early grafting before my best colonies decided to start swarm preparations at which time I switched to queen cell harvesting - after all the bees know best and I'll use queen cells they produce over ones that I've forced them to produce. Queen cells and virgin queens have been introduced to nucs and apideas and the weather looks good for mating. They'll then either replace queens in mite susceptible colonies or be used for colony increase.
A year ago, I acquired some colonies that had previously been treated - mite breeding or mite farming colonies as I call them. This was an experiment for me - I wanted to see whether any were varroa resistant but had been treated anyway, and to make observations from varroa susceptible colonies so I could compare with my varroa resistant colonies. Out of the eight I acquired, two are showing varroa resistant traits. They are uncapping and chewing out and mite numbers are consistently seasonally low. Here's a picture I took last week showing exoskeleton parts on the insert tray and uncapping in the worker brood in one of those colonies:
I'll be keeping the queen lines in these two colonies and monitoring for a few seasons (three minimum) to make sure they do continue to manage mite numbers themselves before I consider making any sort of colony increase from them. But the signs are there, and it shows that there are potential varroa resistant colonies that are currently being treated.
The situation in the mite susceptible colonies was markedly different. Mite numbers were initially low, presumably because they were treated the winter before I acquired them, but they soon started to rise, and rise, and keep rising. There was no uncapping or chewing out at all - the frames covered in capped brood looked so perfect, but of course these colonies are doomed unless I step in and re-queen them from varroa resistant stock. During a brood break you could see lines of varroa mites that had dropped as the brood had emerged, something I never see in my varroa resistant colonies. This is shown in the picture.

Varroa on Board
Another colony that is showing great promise is a swarm I collected last year from a colony that has been living in the wall of a house for several years. These free-living colonies are a great potential source of varroa resistant genetics - how else could they be surviving for multiple seasons without any beekeeper intervention? During last week's inspection I managed to video the moment an almost intact pupa was pulled from its cell across the frame, bees coming over intermittently to pull it or to chew bits off. It's rare that you capture it in action, so here's a still from the video:

Removing Brood
Varroa resistant summary for May:
-
- Put your bee breeding plan into effect, raising new stock from your best varroa resistant colonies and using them for colony increase or to re-queen mite susceptible colonies.
-
- If you have performed swarm control on your colony and there's a resulting brood break, you will observe a pause in exoskeleton parts appearing on your insert boards. This should re-start when your new queen starts laying and worker brood again begins to be uncapped.
-
- There may be a very slight increase in mite drop numbers during the brood break too, but daily drop numbers should still be very low at this time of year. It's important to continue doing a mite drop count even though you may not be inspecting while the new queen emerges and gets mated.
-
- If you can collect a swarm from a free-living colony, then it could be a really good source of varroa resistant bees. Take the same precautions you would with any swarm colony initially to ensure they are disease free, but if you know they are from a free-living colony, do not treat them.
-
- Encourage drone proliferation in your varroa resistant colonies to flood the area with your drones carrying the right genetics
Every month through the season, we will publish an article detailing what's going on in varroa resistant apiaries, explaining our observations, to help those who may be starting their varroa resistant journey.
Messages from EBA and SICAMM on World Bee Day
John Greenaway, president of SICAMM (The International Association for the protection of the European Dark Bee) took the opportunity on World Bee Day to write to the Officers and all the MEP's at the European Parliament requesting support for stronger protection of the native honey bee. See his letter below;

Dear Member of the European Parliament,
On this World Bee Day, appointed by the United Nations (https://www.un.org/en/observances/bee-day), I am writing to you on behalf of the International Association of the European Dark Bee (SICAMM) and its Member Associations who are widely spread throughout Europe. I trust that you are aware of the vital roles of bees and other pollinators in ensuring global food security and nutrition. As concerned citizens passionate about conservation and the precious biodiversity of Europe, we are reaching out to inform you about the challenges facing our native subspecies of honey bees in Europe. We hope to enlist your support for stronger protection of these honey bees, natural European resources, to preserve biodiversity and to help to move beekeeping towards more sustainable methods.
The Dark European Honey Bee, Apis mellifera mellifera (Amm) has evolved, as have the other European honeybee subspecies, over millennia, to thrive in the climatic and environmental conditions in different parts of Europe. The Dark European Honey Bee was the dominant honey bee subspecies until recent decades in North West Europe. It is now under threat in its native geographical range primarily due to the importation of non-native honey bees and modern hybrids. Unlike other agricultural plants and animals, where hybridization can be used to advantage, the reproductive system of the honey bee, with queens mating freely with numerous drones in an area, quickly results in random hybridization of the local population, to no-one's advantage. Native species of honey bees thrive best in its original habitat. Recent scientific studies in Europe have shown that safeguarding the genetic purity of honey bees and promoting sustainable environments for their survival is crucial.
After 30 years of pioneering conservation work in different parts of Europe, we are now experiencing a genuine renewal of interest in the survival of native honey bees, and the number of beekeepers and other persons supporting it is increasing steadily. The time is ripe to highlight the conservation of threatened honey bee subspecies and to develop a more sustainable approach to beekeeping.
We would appreciate your support for the conservation efforts and the protection of our European native honey bees. i.e. the long-term survival of the native bees in their native geographical range. We would also be pleased to receive information on any upcoming initiatives that could assist our efforts. Please send your response and any information via email to info@sicamm.org.
We look forward to your cooperation on this important issue. We are at your disposal should further clarification be required.
Yours sincerely,
John Greenaway
President of SICAMM, on behalf of the SICAMM Main Board and Member Associations
Boštjan Noč, President of the EBA (European Beekeeping Association) also took the opportunity to highlight the unfair competition from fake honey that threatens beekeeping and misleads consumers. See his letter below;

The Eighth World Bee Day - unfair competition from fake honey threatens beekeeping and, above all, misleads consumers!
World Bee Day was declared by the United Nations in New York on December 20, 2017, following a 2014 initiative by the Slovenian Beekeepers' Association and with great effort from the whole of Slovenia, receiving unanimous support from the global political community. The first celebration was held on May 20, 2018, in Žirovnica, the birthplace of Anton Janša-May 20 is his birthday and the date on which we celebrate World Bee Day. The goal of World Bee Day is to protect bees and other pollinators.
As the initiator of World Bee Day, am I satisfied?
In terms of promotional efforts, I am more than satisfied - beyond expectations. But when it comes to supporting beekeepers and protecting consumers, I am definitely not!
Unfortunately, the world is barely-if at all-aware that bees can no longer survive without the help of beekeepers. Without bees and other pollinators, there would be even more HUNGRY people in the world!
That is why it is high time to support beekeepers. Beekeepers are losing the motivation to continue, and if they begin to abandon beekeeping, we are facing a catastrophe in the very near future. There will simply be fewer bees each year, and as a result, the free pollination service they provide will disappear-something that will have a serious impact on food production… So, Europe-it's now or never! This is about bees, beekeepers, and consumers!
First and foremost, fake, counterfeit honey must be immediately removed from the market. It is essential that Europe adopts concrete measures to support beekeepers and protect consumers in this matter before the year is out. Until concrete long-term measures are adopted, Europe should, in the meantime, ban the import of honey from those countries that are most problematic in terms of counterfeit honey. Control over honey must be GUARANTEED at entry points into Europe, as this honey can under no circumstances reach store shelves. This must be done to protect consumers so they can still enjoy real honey-honey that strengthens their health-and not "fake" honey, which can even be harmful to our health.
Europe must also urgently and immediately ensure direct payments for each beehive through agricultural and environmental measures as compensation for the free pollination service provided by bees. This year alone, approximately 50% of bee colonies in Europe died over the winter, and without immediate financial support to beekeepers for hive management, we face a catastrophe both in food production and in preserving biodiversity! Importing honey is possible (fake honey), but pollination simply cannot be imported!
On this year's World Bee Day, I wish for clear and definite protection of consumers and support for beekeepers. Europeans do not deserve to enjoy honey that isn't really honey and therefore should not be labeled as honey at all. Let's not forget: "A spoonful of real honey a day keeps the doctor away!" There is no food security in Europe without bees! Immediate support for beekeepers is essential to preserve the bees and, with them, the pollination service they provide!
I thank all beekeepers for continuing to engage in beekeeping during these difficult times, for caring for the production of high-quality bee products, for maintaining the pollination service of bees, and consequently for supporting the production of more than one-third of the world's food.
Special thanks go to everyone who helps beekeepers preserve bees by planting nectar-producing plants, by using harmful FFS products only when absolutely necessary and correctly, and by deciding to buy bee products from local beekeepers, thereby ensuring the best bee products that strengthen your health!
Let us be aware that the one playing the leading role in everything is the bee - the bee, we say - and once again, we say it: the bee! Without the bee, there are no bee products; without the bee, there is no pollination; without the bee, there is no food production - and also, UNFORTUNATELY, without beekeepers, there will be no bees.

President of the European Beekeeping Association and
President of the Slovenian Beekeepers' Association

Call for Volunteers
Do you have basic video editing skills, or an interest in video editing, and can spare a little time to help BIBBA optimize its videos? We are looking for volunteer members who might be able to do some basic video editing, including time stamping, cutting, and adding cards and stills.
Our videos get thousands or even tens of thousands of views each and are a key part of our mission to help educate beekeepers of all levels, but we need some extra help to ensure that they are as impactful and reach as wide an audience as possible. If you have the skills already then you'll be ready to go, but if you have an interest then training can be provided! Please let us know if you are interested at .
BIBBA supports the banning of honey bees imports.
At a recent BIBBA trustees meeting it was agreed to support a ban on honey bee importation as policy. This is in response to the known threat of tropilaelaps being introduced to our shores via bees from Europe. Although BIBBA has previously not supported an outright ban for some time, this increasing threat leads us to adopt a stronger position for the good of the craft, the bees and our members.
