Winter oxalic necessary if bees treated with oxalic in autumn?

[Finman]

It is, bees like sugar syrup, there is research to see the harm done to the internal organs by oxalic ingestion, which also reduces their life span.

one hundred research about trickling tell that trickling does not affect on spring build up and do not violate queens.

You are wrong. They do not like oxalic acid syrup. From where you have got idea that trickling reduces workers life span?

How do you explain that in Finland hives are alive even if 100% of beekeepers trickle their hives???

It is not so difficult to see what bees do with trickling syrup.

It is mite whick kills. Not trickling. But if guys do not need help in their beekeeping, do as you like. YOur hives.

You are wrong. They do not like oxalic acid syrup.

Bees take oxalic orally through syrup, it is an observable fact.

Oh yes they do, tip a half a pint out in the back of your truck when their in robbing mode, it's gone in minutes, and they don't just come and roll in it.

You know nothing about scientific. I have seen them all.

But when I have linked those new researched to this forum, you have emerged at once to play Tarzan into chain. yeah... last few years

such science...

of course they take. How they could avoid it. There are research about it how bees burn labeled oxalic acid to carbon oxice.

How can bees avoid digesting gasified oxalic acid? Bees tolerate some amount of oxalic acid. Researcher group made 6 years work to reviele out, how much. How many of your have read, or at least seen those studies?

Japanese have gasified oxalic acid againts varroa 50 years. Nothing new in it.

So are you now saying that bees do drink oxalic syrup?

This one is from August 2017, there are also lots of older ones that you have not seen.

This was in small laboratory cage. Not in natural hive.

As you know, assistant bees start to die after a week in queen cage.

I trickled my hives a moth ago. What do you think, how many weeks my bees will leave since now?

Do you know what is sublethal effect?

The British trickling method

Fill the 50 ml syringe with treatment solution (oxalic acid).
Remove the roof.
Remove the top box (shallow or deep) with cover board in place and rest it on the upturned roof.
Treat the lower box with about 5 ml solution/occupied seam of bees.
Replace upper box.
Remove cover board and treat any seams of bees as for the lower box (the upper box will often have no bees, especially if the weather is cold).
Replace the cover board and roof.

---First of all.

50 ml is meant to double brood langstroth, where boath boxes are full of bees.

If the colony has one brood over winter, then trickle 30 ml.

You are not very sharp with your advices.

Where you need science?

Glad you agree with us - so why are you arguing with yourself - obviously you also agree with us that you talk utter bllox

You may have three degrees won off the back of a cornflake packet But I have Gladys knight and the pips on my side

heh heh. I have read trickling researches 20 years. Do I now tell all what I know because British beekeepers do not know what they do.

I am not here learning. I am teaching.

If I need information, read it directly from researches.

 

[Hivemaker.]

This was in small laboratory cage.

The ones that come to drink it out the back of the truck were not in a small cage, and no one forced them to come and drink it, but they did.

Here is another one for you, they tested using a higher dose.

Short term negative effect of oxalic acid
in Apis mellifera iberiensis

Nanetti,
2001). These negative effects seem to appear when the most effective solution of 4.2% OA is used, but 3.6%OA is also not well tolerated by bees when 50 mL are trickled on.

Negative long-term effects on bee colonies treated with oxalic acid against Varroa jacobsoni Oud.

Abstract - Two oxalic acid treatments were given to five colonies in autumn and five colonies in spring. ..................... A long-term study of the colonies for 3-4 months after the last application of oxalic acid showed a statistically significant negative effect of the acid on brood development. In addition, three queens died in the treated colonies. © Inra/DIB/AGIB/Elsevier, Paris

​

Funny European varroa group reseached all necessary in the years 1998 -2003.

USA has come 10 years after Europe.

What Britain has learned in 20 years. It want to buy oxalic acid 400 €/kg. You cannot use 10€/kg stuff.

I wonder what Jenkins is trying?

That is the problem, you are reading old out of date research, move on and get up to date.

That study has been done with oxalic acid water spray in the year 1999.

I can read what I want.

The treating methods are exactly the same what they were published in the year 2003.

Very common "English Intellectual poking". I have got used to it. A good joke can be told only once but not every week.

NOw it was a big idea to help Britain and France to treat properly mites.

But you really love to shoot messenger.

Your super talent Jenkins does not even read texts what he offers to others.
