That was the subject of an attempted study here in Ireland some years ago, I communicated with the author, he like me, was of the opinion, that the breeding efforts of VSH breeders (like B+) would result in more and more resistant bees (meaning they don't need treated - at all) coming onto...

Yes, I've heard mentioned (I think it was Seeley at the last UBKA Conference?) 85% of total varroa in the hive is left behind when the swarm leaves; so it would stand to reason that swarming could extend the lifespan of a queens' colony - as it moves with the queen from tree to tree (in the...

I've read this paper (and the papers it cites) and had missed the section about the Arnot forest bees and the Japanese haplotype. "A pairwise comparison of colonies established by Arnot Forest queens from the bait hives and colonies of unrelated mite-susceptible bees did not reveal differences...

Ok, so there is a lot to unpack there, but as I think emotion may be affecting this discussion somewhat lets focus on one statement at a time. You have stated -while referring to my above statement- of "virus resistance ... is theoretical" (amongst honey bees, within a local context) "is not...

Have you read the finished published paper? An average annual 55% death rate seems to suggest that the "free living" bees of Ireland are not even adapting to Ireland! Let alone varroa!

Unless you can explain the reason for the survival, we can only say they are lucky! Of course the survivors have low disease, etc. otherwise they'd be dead! The west coast of Ireland has less DWV in their bees than the rest, they appear to have less varroa, their longer overwintering period...

I've heard this said before about the Amm, until I see research to back the claim up, I'm more inclined to use Occam's razor (the simpler explanation is preferred) to explain supercedure - in that, IF seen in ANY other bee it is simply said that there is something wrong with the queen, ie: low...

The vast majority of varroa are actually IN the cells, so yes, the colony leaves most of them behind. When a new varroa leaves it's cell mum goes of to reproduce (I think she can do this a few times) while the kids need to feed off a bee for a couple of days, it's likely these mites that will...

That's what I would expect, with or without 'tolerance genetics' etc. Swarms have very few varroa, they've left them behind! Hives which have swarmed have a prolonged brood break inhibiting the reproduction of varroa. There is Survivorship Bias here (Google it); you could take ten hives, half...

"innovative and interesting" I merely referenced newer DNA research, that has upturned previously thinking on Apis mellifera relatedness, if that's not "innovative and interesting" I don't know what is? By the way, now that you have brought up the subject of "innovative and interesting", can...

So you clarified in Posting #363, that your claims were based on wing morphometrics, fair enough I can see from where the misunderstandings ocurred; but now you are saying the claims (in part) are what was said to you by an expert on bee genetics and iberiensis (did he also tell you the...

Troll! Excuse me ! What?!?! Do you have a short term, or selective memory problem or something??? YOU brought up the subject of A. m. iberiensis, and it's relationship to A. m. mellifera, YOU said "...and the close relationship between mellifera and iberiensis..." I merely pointed out there was...

Sorry, didn't make myself clear: The figures are my own and other beekeepers here in Ireland - there are a few exceptions as low as 20% and as high as 90%, but they seem to be one offs. What results do you get, for introducing a sealed queen cell in a apidea / mating nuc, etc. and then six...

Can you give us all a link or some more info. on this NEW discovery by researchers? Here is the link to the paper I based my statement on, that A. m. iberiensis is not in the M lineage. "...A. m. iberiensis from Spain and Portugal (Fig. 1). The Iberian honey bee was nested within the A lineage...

If natural selection will do the breeding then we should have seen it in the Primorsky (Russian) bees, and on closer examination these bees are no more tolerant than standard bees after several years of non-treatment; in fact that's what has consistently happened... beekeepers claim their bees...

Table 1 of the paper you have cited makes reference to "spatial distribution of colonies" which obtains this information from Seeleys Arnot Forest Research, and further research which follows up on it. I have read most of the papers cited in that paper, I wish the authors would have as they...

https://zoologicalletters.biomedcentral.com/articles/10.1186/s40851-020-00158-4 This previously cited paper identifies three traits which are closely related or dependant on each other, Hygienic behavior, VSH, Suppressed Reproduction; it also includes Grooming - long discredited and better...

Yes, that's why it's so difficult to breed for, because of the different genes involved. For example the A. m. intermissa removes the capping on their brood when they detect a reproducing varroa mite, but Do Not remove the pupa! The mother mite leaves the cell and surprisingly becomes infertile...

Bear in mind that if an organic type / treatment free beekeeper manages their hives by killing of 85% of the mites in May of each year, one would expect few deaths from Varroa ... that's what's happening with your observed swarms, it's not that they are varroa resistant it's that they are...

Studies I've read have found that within the hive the likelihood of a capped brood being opened and emptied increases with multiple factors, the presence of a mite, a reproducing mite especially, the presence of virus', especially lethal ones - this increases with the presence of mites, etc. And...
