A good report on Elgon bees

I have just returned home from the annual meeting of our local bee association. Susanna Kivling spoke about the Beescanning project, beescanning.com  We were also discussing to establish an Elgon mating place for queens of the members. The best report I got after the meeting from Arne Andersson who got two queens from me last year of the line H131. He treats all his colonies every year for varroa. So he treated these two Elgon colonies with sublimating oxalic acid (“heat-steaming”) some time ago. He decided to treat them again with trickling oxalic sugar solution as he got so few mites from the treatment. These two treatments gave together two mites each from the two Elgon colonies. Another type of colony close to them dropped altogether 1000 mites. Cellsize? 5.1. I hope the Elgon colonies survives the two tough treatments so I can consider grafting from them next year.:)
