  1. Had thought of this but hadn't really checked it out as an option as I am pretty sure it won't fall into the cheap category - penny pinching dutch genes kicking in.
  2. PS. Are you advertising these stencils on the forum? If not, you should.
  3. Printed and laminated numbers sound straight forward and simple. I'm not a smart phone user (and hope never to be) so just numbers and record keeping on paper will do me fine. Thanks for sharing.
  4. Thanks Trevor - have one of those. Sorry should have been more specific. I want unique identifiers on all my hives/boxes as I want to easily collect and collate data for all my hives regarding performance and varroa monitoring.
  5. I'm looking for a cheap, permanent system for numbering my hives/boxes. I've had a quick hunt around but haven't found anything useful as yet. If anyone has a good system in place could they please share some details?
  6. Happy to help. I have taken a few people thinking about getting some bees out and they have all loved actually going through beehives. Keen people in Dunedin are welcome to get in touch via a forum conversation.
  7. There can be many nests in not that big an area. I remember one year (around 20 years ago) I spent a bit of time tracking them down during the summer holidays. Around our house and surrounding farmland in the Western Bay of Plenty (within a radius of a kilometer or so) I found more than 50 nests. With bush around your only option is really bait stations of some sort.
  8. I remember reading somewhere that wasps are apparently pretty good at detecting carbaryl in food and won't take it back to the nest. DOC or Landcare (I think) did a decent trial a little over a decade ago using fipronil in cat food. Is supposed to be extremely effective. Apparently they neglected to get permission from Bayer to use Fipronil for killing a Hymenopteran species though and Bayer were very unhappy as wasps are too closely related to bees (Fipronil being a neonicotinoid). You might of course be morally opposed to using an insecticide of this class or a Bayer product... If y
  9. I was under the impression that as well as a bee colony getting robbed out as they collapse from varroa, the last bees from the dying hive are quite likely to bail and find another hive. If this does happen it is quite likely this would be where your hives on the ends pick up the extra mites (e.g. swarm or poorly managed beehive on a neighbouring property). Thanks again for sharing your data - really interesting stuff! Enjoy the conference.
  10. Hi Tony, First of all - pretty encouraging results! The oxalic is obviously doing a good job. Given that only the odd hive has brood I don't think it matters too much when you put a post-treatment in (probably the sooner the better - just in case you have some mites coming in from an external source). You are doing this to get an idea of the percentage of mites killed by oxalic. Given your numbers (bigger average mite drop in the oxalic treated hives) I'd be very tempted to give the ones that got bayvarol in the test some oxalic as a post-treatment (to test how well Bayvarol is working)
  11. Might be a good idea (with regards to refresher training) if commercial beekeepers who find a hive with AFB can then get in contact with a local club and offer to show whoever is interested the positive hive. I realise it would be short notice but I find it hard to imagine no one would have time. Actually seeing AFB is a whole lot better than photos.
  12. I can have a go at this. Might be a few days before I have time though.
  13. Bayvarol should work pretty well as a positive control. That might be the best way to do the experiment if there is brood in the hives. Both treatments only target phoretic mites so counts at 24hr/48hr post treatment for oxalic, bayvarol and just sugar syrup should give a reasonable idea as to how effective the treatment is. If you can split the treatment groups a little more evenly (eg 4 pallets oxalic, and 3 each of Bayvarol and sugar syrup) it would give more robust results. Will you have a look through the hives to see roughly how much brood is in each? Would be useful data to have wh
  14. That's exactly right. It's all about seeing how well it works and if that equates to well enough to make it a regular part of your treatment regime. I think how long you leave the Bayvarol in for is your call. You know much better where your hives are at. The main thing is to have sticky boards in place when you put the strips in so that you can compare counts between the test and control hives. When it comes down to it I what I know comes mainly from reading and talking to others. I found varroa in my hives for the first time around 2 months ago. You have been dealing with it for ye
  15. Hi Tony, I've just spent a bit of time reading back through this forum thread and having a look at some of the European data. Became quite a heated debate for a while there! I think Finman did his best to tell us that oxalic acid works well as a winter treatment. I would take his advice over anyone else's as he has experience on his side (and this almost always trumps a well read but inexperienced point of view). I hope he is still a member of our forum. In terms of this experiment, I would certainly include all the hives. What I described above was an ideal set of conditions for doing
  16. Couldn't agree more Tony. The great thing about science is that anyone, anywhere can do it. Oxalic acid has been used in Europe for a long time already and is a preferred choice, especially during the winter break. I highly doubt they'd still be using it if it didn't work. From a scientists point of view - we do have to set up experiments in such a way that results are reliable and reproducible in order to stand up to peer review and get them published. I don't know what our Bee scientists did in the way of experiments with Oxalic acid but my assumption would be they couldn't get consiste
  17. Unfortunately I think it is a very long way off. Breeding for varroa tolerance while treating with miticides is very hard work and progress will only ever be very slow. The same can be said for breeding for varroa tolerance without the use of miticides when the beekeeper down the road is using them. I'd settle for bees that only need treating say once a year...
  18. I have a pdf copy of the paper. I won't post it on the forum as that might cause a few copyright issues... If anyone really wants to read it I can email them a copy as long as it goes no further.
  19. PS. They should probably send some of their honey to AsureQuality for testing (TutinTesting Honey - AsureQuality Limited). Does cost a little...
  20. I would also think Tutu is the more likely culprit. Karaka is problematic for bees (see attached file) and every beekeeper should be well aware of the problems with Tutu honeydew. karakahoney.pdf
  21. I asked Margaret Roper of Asure Quality about the bee database not that long ago when I registered another apiary. She told me it is limited to beekeepers with 50+ hives at the moment but will become available to all registered beekeepers in the near future. I agree with Greywulff - as much as I'd like to know exactly who has bees and where it would expose everyone to the few dishonest beekeepers that are out there. It is more difficult to keep bees in good shape with Varroa and with Manuka honey prices a year with good weather at the right time can make beekeeping very lucrative. This comb
  22. I also got this letter. Frans (Laas) told me this was in North East Valley somewhere. He knows of all goings on with respect to AFB so is a good person to get hold of if you want more information. I believe there have been at least 4 AFB hives found in Leith Valley (where I live:() and a couple in NEV too over the last couple of seasons. The Leith Valley had apparently been clear of AFB for around 20 years prior to this little outbreak. It certainly makes me a little more nervous knowing AFB is close by. All we can do is check our hives thoroughly and frequently so that if it crops up again
  23. I would say there is no excuse for the AFB.org website to be out of date. It really needs to show up to date information and details on courses to come rather than ones that are in the past. I think the best thing to do is take it up with the Management Agency. I imagine many of these things are done by beekeepers who are elected representatives and that things will be up to date again soon as they have some downtime during the winter break. If this is the case then it could perhaps be an area where the Management Agency and NBA could enlist the help of some willing hobby beekeepers who are no
  24. It is exciting to hear that there are beekeepers that actually have a large number of hives doing this. I certainly look forward to hearing all about it. Do you know of any other commercial outfits doing this level of monitoring with an eye to being able to select the most varroa tolerant bees to breed from?
  25. Hi Alastair, Just wondering how these are going?
