Very interesting to hear about your similar experiences. It might actually be, by both of us, that it is just what happens according to Mendel laws: variation opens up!You mention that his bees seem to have a different mechanism for mite resistance. Can you describe the difference?
I've experienced problems when combining genetics from two different parental lines with different mechanisms for resistance. In one instance, the first cross was highly susceptible to mites. Later generations stabilized and developed better mite resistance than either parental line. For reference, this was when I crossed queens raised from my first mite resistant queen with drones from Purvis queens.
+1........ I understand the fascination with massive hives, but I don’t share it. I’m fascinated by small, healthy colonies that require little work other than adding supers and harvesting.
I have had thoughts about my location. In the old days, when I treated, I got max. 150 kg honey from my home yard, I considered it so poor that I usually kept only 4 hives on it. In comparison I usually had 6 hives on my other yards and I could get 400 kg or more from one place.“Pure Lundén Resistant Queens make smaller than average brood area, but of course not treating must have an effect.“
Sharp observation. Location makes so much difference in what works.
Thanks!I am subscribing to this thread in hopes to glean from your experience as you have time to share
https://www.beesource.com/forums/sh...are-the-real-treatment-free-beekeepers/page13Thank you for the update- I am laughing about the Mensa candidate comment and I am sure there is a good back story to this one- I've seen the quotation in your signature...
