Advice re varroa treatment

[B+.]

even without the burden of viruses, at what point do the mites themselves impose a meaningful burden on the colony.

I don't think anyone can really answer this question.
If, as appears to be the case, it is the virus load that does the damage and the varroa are merely the vector, then, it follows that we need to investivate the varroa more closely to determine what viri they carry.
It has been assumed for a long time that the varroa do the damage and, I think, this is why so much energy has been put into managing varroa. Well, IMHO, it is still useful to control the vector, but, we may not be getting the root cause of the problem.

Outside university no one has afford to to identyfy viruses. And, what then., if you know the viruses?


Only what you can do is to treat varroa. over 90% of UK beekeepers are 2 hive owners. It is good if they know couple of methods what to do with mites.

Varroa is the basic reason. If you treat them well, you do not have extra proplems.

Disease problems were before varroa.

Root cause problem? It is university problem. That is why they have beekeeping line and a professor. Yeah. They have one degree or more.

No one has given virus control advices, - so far. Not even hobby beekeepers.

When Nosema cerana started to spread, spesialists told that it will kill all hives. Now most of nosema cases are cerana and nothing has happened.

Our researcher took from my hives brood pieces from 10 hives 20 years ago. Excamples went to France. They researched viruses from them. And what has happened?

You may repeat some reports, but it helps nothing.

But how many angels can fit on a bee mite?

Reindeers sre 600 km to North from me. Most of those people live on Norway.
Reindeer has been tamed about 1000 y ago. Quite young farming as semi domestic animal.

Work on varroa surviving strains showed that removing Varroa (with treatments) they gave you nearly 2x as much honey as the untreated colonies.
Might be difficult to separate the effects of the viral load from the parasite load.
It doesn't take a genius to work out that a sick bee with a heavy parasite load will not be as an effective forager as a healthy unparasitized bee.

What's interesting about the French paper cited above, which is only 9 years old, is that there is no mention whatsoever about any virus contribution to the outcomes recorded.
It shows, I think, that the knowledge about Varroa destructor is expanding very quickly and in a year or two we may be able to answer some of the difficult questions that we are currently struggling with. It's only just over a year ago that we found out about DWV type B. There's a lot more to come on the viruses but "the hounds are on the scent"

Given finman's predilection, I was going for prion disease.

+ type, I hope. It sounds so positive.

prion disease = mad cow disease

It is one of those topics still very sensitive in the UK.
