Perone Hive?

So nowt do with hygienic bees.

Not necessarily, and not the same sort of 'hygienic action' as tested by LASI when they kill larvae with liquid nitrogen (is it liquid nitrogen?).

Ron Hoskins bees are noted to chew at mites, the same as A cerana seems to http://www.sciencedirect.com/science/article/pii/002220118790125X

That happened 5 years ago. Where are those resistant bees now?

There is more 5 years old information

Those actual worker bees will be dead by now, as bees do not live for five years, but their descendants will be in his beehives.

Are those descendants bees too, or are they turned Zombies?
Zombi honey?

Yes, i would imagine they are bees.

Was it Ron's bees they used for this study!!!!? As it states the European bee failed to remove the mites from brood and adult.

Serious question is that somebody "invents" a hive like that, a hollow cavitys and many thinks that bees can survive there by their own.
On another hand, many talks about abandoned hives. No difference with those two cases.

When varroa arrived to Finland 35-40 years ago, there were lots of hive holders, which did not nurse bees, but they kept some hives on their home ground. They opened the hive first time when swarms left in the middle of summer. Normal swarmin date was 26.6. They captured swarms and took some honey from hives, 5-10 kg. Many sold those swarms.

Same was with skeps. You cannot open it and you cannot do anything to stop swarming or breeding bees. Just in summer a small 10 kg Super with excluder on top.

Yes. Varroa killed the whole this system in couple of years when mite arrived to the district.

And a human generation later, beekeepers think that nature will heal the wounds and kill the bad mites from earth.


Perone hive has no difference with the style 50 years ago, or 200 years ago.
Diffrence is that modern colonies are 3-4 times bigger than 200 y ago.

[For want of a better word]

Diffrence is that modern colonies are 3-4 times bigger than 200 y ago

and... the bees are mostly today non endemic imports
the varroa mite was not known as it had not traveled across the English Channell
Polystyrene hives with open mesh floors were unavailable... as were removable frames etc etc etc

The bees' ability to hold the winter cluster temperature is independent of whether there is space above, below or around the cluster. The cluster is where the warmth is, and it doesn't matter how much space is above the cluster.

One might think that since heat rises, there must be a zone of warm air above the cluster, but there isn't really. In winter, the temperature of the area more than 2 inches away from the cluster (including the area above the cluster) is the same as the outside temperature.

No, and he doesn't keep A cerana either. There's nothing to gain from my trying to paraphrase or précis what Ron says on his site http://www.swindonhoneybeeconservation.org.uk/about-us/

It's worth trying to get him to speak to your BKA, but he's quite a busy man so you may have to wait a while.
