Selection and no chemicals but a too close to treatment bees In 2019, Sibylle and Wolfgang bought 3 Elgon colonies from me. They were all treated for varroa with half a dose of thymol that year. Since then, they have
More treatment free Elgon bees
Treatment-free bees – one loss March 20
Finally! No treatment! One loss! I have had a long journey to achieve treatment-free bees. I’m obviously thinking of the varroa mite. In 1989, breeding material was retrieved in Kenya: https://www.beesource.com/threads/exploring-monticola-efforts-to-find-an-acceptable-varroa-resistant-honey-bee.365571/#post-1843973 It took until 2007 before the varroa mite was
Breeding varroa-resistant bees pays off!
Breed varroa-resistant bees! The study of EurBeST states that varroa-resistant bees are important for beekeeping. In 2017, the European Commission appointed an international group of bee researchers led by the German Bee Institute in Kirchhain to find out more about
Can resistant colonies give a good crop?
Strong Varroa resistant bee colonies Some suggest that one important trait for varroa resistance is smaller brood nest and less brood rearing. That may be so for some stock resulting in lower growth rate of varroa mites. It’s also resulting
Varroa resistance – the two traits
Traits for Varroa resistance We have found in our Varroa resistant project in our local bee club that when you begin a project like this, checking the varroa level is the most important tool, if you plan to treat colonies
Help for varroa resistance
Resistance against intruders One of my bee colonies (Elgon, combinationof Buckfast and Monticola) started to superseed their queen, but the new queen evidently got lost. The colony ended up with egg-laying workers. I discovered that in August. It had several
Right time for monitoring varroa in spring
Spring cleaning of varroa The most important time for monitoring the varroa levelis in spring. (Other times can also be important!) Last year I realized that the varroa level can differ quite a lot for the same colony just a week
Varroa Resistant Bees In Norway
Varroa Resistant Bees Get $1 Million In Norway Published in Bee Culture, May 2020, pages 75 – 77 Dr Melissa Oddie, a Canadian researcher, will continue her research for at least two years based on the Varroa resistant bees with
Cooperation in the Elgon area
Some years ago, varroa resistance had risen noticeably on my Elgon bees. Then I started to give away some breeder queens to the neighboring beekeepers. And they promised to graft from them to make new queens. In particular, Stig-Åke Gerdvall
Varroa resistant bees
– African bees are resistant to Varroa mites, or become resistant in about 5 years after the mite has come to their hives, in Africa and Americas – Italian bees on an isolated island close to the cost of Brazil
