Advice re varroa treatment

[charlievictorbravo]

You may be on the right lines there - just looked through my notes from the talk again on Sunday and found one line which may say just that - they were just bullet points so can't be 100% sure of what I meant when writing up (I'll have to get a sustificit in note taking) but I think the gist was that the chemical matching that made them invisible may be affected by DWV B.
Interesting note I saw again was that Varroa destructor can no longer co-exist with Apis ceranae - so things are always shifting.

If this were the case, and I think it could be (no evidence, just a suspicion), the next question that arises is "is the type B virus that it transmits affecting the mite also, such that it cannot hide its scent" or "is the type B virus in the bees conferring on them the ability detect the hitherto scent-camouflaged mite".

How the bees deal with the mite, once detected, is dependent on which trait their colony has developed - entombment, ankle-biting, brood-culling, mutual grooming, etc..

To summarise, the hypothesis is that the Type B virus somehow allows the bees to detect the mites and the bees then use a variety of hygienic behaviours to deal with the intruders. The type B virus comes first; the hygienic behaviours follow.

That sounds truly good. You spray virus on the bees and then bees kill the mites. If that is true, it would here and there miteless colonies.
.then you feed healty hive's honey to another hive and it gets vaccination.

And Nobel prize is yours...

Yes, but the times they are a-changing .....

Why don't you phone to some old fart?
.at least you get a right answer.

The bees may be detecting and removing the diseased larvae thereby disrupting the mite's reproductive cycle. This would be indirect detection of mites in the brood, but would produce the known sequence of events.

How the bees deal with the mite, once detected, is dependent on which trait their colony has developed - entombment, ankle-biting, brood-culling, mutual grooming, etc..

There is near certainty that more mite tolerance traits exist but have not yet been described. I have seen mite tolerance in africanized bees that did not appear to correlate with the known resistance traits.

But there's one thing we're forgetting - The findings so far is that DWV B infected colonies are not showing some phenomenal hygienic tendencies in fact the whole hygiene thing seems to be a smokescreen that's distracting everyone.
DWV B colonies are thriving, bringing in a good yield and happily existing with a very heavy mite load and have no need for hygienic behaviours.
Prof Martin was of the opinion that in Ron Hoskins' case it was just sheer coincidence that of the massive colony losses he'd sustained the survivors had hygienic tendencies.

Given the population prevalence between 1 and 2 percent for hygienic behavior and given that RH's bees expressed a high level of hygienic behavior, the probability it was coincidence is near zero. It is like the odds of opening an oyster and finding a 1 ounce pearl... except that Ron Hoskins found a bunch of 1 ounce pearls. Some things are not coincidence.

 

[jenkinsbrynmair]

loads of colonies died with him (he will never admit how many) - his records are in disarray, every one of his surviving colonies has DWV B there is strong evidence from all over the Southern hemisphere that DWV B colonies can coexist with a heavy mite population yet you're pinning all your hopes on the suppositions of an elderly backyard beekeeper with a handful of hives.

I suppose you're voting Trump as well?

That loads of colonies died tells me the survivors had something the dead colonies did not. It was probably associated with hygienic behavior given that the resulting colonies are hygienic. How many colonies died is irrelevant, how many survive and that it is repeatable is what counts. You have to give RH credit for doing something the university professors didn't or couldn't.

You're off your game JBM, I'm not relying on anything re RH's bees. Is your job serving tea at the pink tea party pavillion causing mental confusion?

 

[jenkinsbrynmair]

That's one definite for the inbred redneck republican vote then.
Hope your bees are immune to nuclear (sorry, nookular) holocaust as well as everything else................

Ah gaht mah edication frum the man what sales em online. Says I gradicated from a real fancy collage. Whar'd you buy your'n, it might be be better'n mine. I mought ned to upgraid.

Go back to serving tea, happiness awaits.

When this chain begun, the members did not have basic knowledge about oxalic acid or about treatment. On next step we are inside virus things and mite resistant bees.

The more difficult the issue, the more easier the answers.

The best treatment method is 30 y old. Found this year.

......what is going on ....

JBM - I expect you've already mentioned it, but when and where did you hear/see Prof Martin? Is his research linked with the chap from Exeter, whose name I can't recall.

There are grooming videos in YouTube. Many of them guard bees on entrance and they inspect robber bees. Need to be imagination included.

Stupid bees. Why they so not clean inside the mites.
