Bees needed for research trial

Recommended Posts

apistan/bayvarol was tested by mark years ago.

only one of interest would be apivar (Amitraz).

if thats what they are testing would it not be better to send a jar of mites?

 

We take the bees and wash the mites off them. We need the sample to be of bees so that we can use the same laboratory method on all of them and keep it scientifically accurate.

Resistance changes over time and because insect lifecycles are very quick these resistances could alter.

So there isn't any point in tracking its spread across the country?

 

We would like to gather samples from all over NZ to try and see where (if any) resistance is

Would it not be Varroa resistance but then is it viruses? which ones? i assume varroa as they don't want to have them treated. I would then be curious why they don't go back to no spring treatment either.

 

Bees and varroa breed very quickly. Mites from spring last year would be dead and a new generation would be in the beehive. We want to test these and see if they were bred from resistant mites that survived the spring treatment

Kinda does to me, resistance to varroa to me would be if they haven't been treated since at least winter last year a five six month break without treatment i would not call resistance but 8 to 12 months beyond well then you really got something to work with. But i'm only surmising i'm no scientist and don't know all the info. but if they wanted hives not treated for that long some advance notice could be given I would not treat selected hives now and get them though winter they can have samples of the survivors. I've done it before for myself out of 40 hives no autumn treatment and last spring treatment was thymol I had 6 survive and of those six four were good strong hives they went though to my drone yard for drone production, to me thats what i'd be looking at, but again some more detail about research be good.

 

We are testing the VARROA's resistance to chemical strips - not the bees themselves. Therefore we require varroa that has survived in the colony and has then bred and perhaps passed on this resistance

Yes I was hoping she might too :)@Sarah Cross are you there?

I still have some hives I have not treated for varroa and would be happy to send a sample if you would let me know, do I get my results?

 

The results will come from the overall organiser of the trial and will probably be in a report form so not for each specific beekeeper but more in geographic area

My email is in the original posting

Not sure why they need to be treatment free - if indeed resistant. Send the varroa to us @tristan if you can sugar shake them off and chuck in a small tube of water - we have developed some prototype tests for those resistant markers. Just checking a new assay currently

 

Where do you work John?

Just to get the requirements straight. You would like 300 bees from a hive that have not been treated with commercially purchased strips since spring?

Hi Sarah,

 

Could you be interested in post treatment? If I find a hive/s appearing to not respond positively to treatment and then wash some bees- then find some mites?

yes i would like only one sample from each beekeeper from one hive. Results would be given in a report so possibly not for each specific person but just the overall findings

If I'm going to kill 300 bees I think I should be notified what is found on my own bees, I understand the amount of effort in notifying everyone who takes part in what is probably a very large study.

 

But it just seems strange to offer a sample and not get a result..

It doesn't make me want to go out of my way to get a sample.

I don't exactly like putting bees in the freezer.

It's a bit like donating blood. One day you might need transfusion but will not get back what you gave.:)

That's a good way of putting it I suppose.

 

I don't know, maybe it's just me.

correct. If you email me your address i will send you a container and instructions. sarah.cross@plantandfood.co.nz

If that's the case then I have several that have only had formic or oxalic acid since about April 2016. Most of them have low mite levels but if you'd like a sample I'd be happy to provide. We are urban fringe, Hawkes Bay.

With all due respect to you both, it appears that the right hand isn't aware of what the left hand is doing ?

Independent researchers coming up with answers instead of colluded results.:)

We are neither the left hand, right hand or even the little bone in the inner ear of Plant and Food. Also, as a company many of our things stay under the radar until we think we have something useful. And we think we have a couple of useful things coming soon . . .

Oh good .... it just seems that if one is doing research, then why not communicate with other researchers?

Maybe for the same reason if one is beekeeping, they don't always communicate with other beekeepers . . .

Which brings up back to 'collegiality'.

Surely it is all about intellectual property. Then of course, who would own the information after it has been discussed.
