  1. The Queen in this image, while not one of mine, looks identical to the daughters reared from from our F1 Hybrid Breeders. The Queen in the image is 50% Carniolan, 50% Italian. What the colony looks like depends on what she mates with. The sub families resulting from her mating with a carniolan drone will look like the worker directly above her, and matings with more yellow drones will sire workers like the rest of those in the image, ranging through to very yellow.
  2. Yea, I have got some good ones on my work computer. I will post them later tomorrow.
  3. Are you guys all trying to flush me out with all this anti-carnica fire?! You succeeded. Of course Carniolans are still being sold. There are far more carniolan and F1 carniolan X italian Hybrids being raised and sold commercially than there are so called 'pure' italian Queens. Every single Queen exported to Canada is either carniolan or F1 Hybrids. Every production Queen produced by the Kiwi Bee Queen units, Apiflora, and most of those produced by the big King's Queen units are F1 Hybrids. It would be just as ignorant for me to label all yellow bees rubbish, or claim that yellow bees swarm more than carniolans, or claim that italians are responsible for nasty hybrids. The truth is that both carniolans and italians are good commercial bees. I can't say the same for mellifera. Crosses between the races can be savage, but you can't blame one of the races involved, it is because they are racial hybrids. Most of you carni bashers, either have little experience working with them and manage them the same as you manage your yellow bees, or have never even tried them. If I managed my yellow bees the same way that I managed my carniolans, then my yellow bees would starve before spring. This year has been a particularly swarmy year up north, even though the spring has been crap, and we have had more swarming in our yellow bees than in our carniolans. Any way, back to the original Question- the answer, as I said is yes, the Kiwi Bee Breeding Unit is maintaining and improving two Closed Populations, one yellow, and one carnica. Each season, we cross the two populations, inseminating yellow virgins with carnica semen, the resulting F1 crosses, are utility Breeders from which we rear all of our production Queens, these Queens are very uniform, very vigorous, very productive, and a pleasure to work with. In a trial last year, they performed significantly better than the straight BB's stock in the trial. We sell these F1 Utility Breeders to anyone that is interested in giving them a go.
  4. It would still be rubbish honey here if not for the research of one man, a Welsh migrant, Dr. Peter Molan. We have had SO much as an industry to thank him for. I remember a Conference many moons ago, when the conference was asked to approve what I remember to be a 25 cent per hive levy to help fund Peter's research, there was not a lot of support for the levy, and very strong, vocal argument against it. As for the program tonight, I don't think we made a strong case. Remember, Leptospermum scoparium is probably an Aussie immigrant from Tasmania, its' nectar is collected to produce Manuka Honey by European Honey Bees which were first introduced into NZ from Australia.
  5. I was only sounding a note of caution. I think you have done a great job further developing this new delivery system for OA which appears to be a cheap, effective varroa management tool, and as you say this system could be used to deliver other Varroa Killers. Good on ya. I certainly wasn't trying to stop people using it to manage varroa, just flashing a warning about using it exclusively. For decades OA has been used to managed Varroa with no solid evidence of mite resistance, but, until recently, it was always used in a Shock and Awe treatment of Broodless Colonies(either natural or induced broodlessness) with an OA syrup dribble or spray with treatment being repeated twice at the most because of the toxicity to Bees, and then no more OA until the same time next season. Now what you are doing is totally different, and the risk of mite resistance is very much higher.
  6. I guess with your dismissal of 'synthetics', you are including amitraz strips as well. I haven't been following this forum much lately, but in a quick glance now, everyone seems 'staple' obsessed. I just want to voice some caution. This is a relatively new way of administering OA. It seems to rely on almost constant treatment. While to date there is no known evidence of mite resistance to OA, that will change. Beekeepers cling to the hope that because the mechanism of toxicity to mites of OA is different to the 'synthetics' then somehow this will protect us from mite resistance. It won't, constant exposure will just see mites find a different pathway to resistance. It is just as stupid to constantly treat with OA, as it is to constantly treat with fluvalinate, flumethrin, or amitraz. Remember as well, OA is toxic to both bees and mites, just more toxic to mites, there is not a lot of margin there- don't treat it like it is a Bee Vitamin. As well, best case, no resistance, you 'Staple' guys seem to spend most of your time with the nuisance of a brood nest full of staples(damaging a lot of brood comb), and constantly monitoring mite levels, doesn't sound like enjoyable beekeeping to me. Having all your eggs in one basket is never a good idea.
  7. That would be more likely labelled MGO 40, very low quality "Manuka", shouldn't be allowed to be labelled Manuka, would be NPA(UMF) about 2 plus. Genuine UMF 40 plus would be priceless!
  8. @Philbee The Staples can't take all the credit- there is a LOT of Carnica in those mongrels of yours!!
  9. So sorry, what I meant was that you looked older and wiser than expected- or is that just digging a deeper hole for myself!
  10. I don't understand the mechanism, but I think it is almost certain that some high C4 sugar results in Manuka have little to do with sugar syrup feeding, and most high C4 for sugar results in Kanuka have little to do with feeding sugar syrup. For us in the Far North Kanuka is a second, totally separate crop. Manuka boxes come off, and the Kanuka boxes go on, yet some years, like this year, when we had an amazing Kanuka flow in our area, and ended up with a very big crop, of very pure Kanuka- had a 3-PLA level of 3100mg/kg(3-PLA is an amazing Kanuka marker making it worse than useless as a Manuka Marker IMHO), yet, virtually everyone had highish C4 sugar results, and it is almost impossible for those results to have had anything to do with sugar syrup feeding.
  11. Not sure where Gino worked, but I think in most places, best commercial practice is to dust across the top bars with an icing sugar/oxytetracycline(OTC) mix every time you go into the hive before the honey boxes go on, and then for good measure, some still use extender patties, which are a vegetable shortening, sugar and OTC delight that is thought to give you antibiotic cover during the honey flow. The problem, with only treating in the spring, is that the colonies break down with AFB during the honey flow once the levels of OTC fall below levels which inhibit AFB infection, and whole lot of AFB scale is produced which creates the AFB problem you'll face and treat for next season. That is the slippery slope you fall down, once you start trying to control AFB with antibiotics. This is an ailing industry. It might not be obvious to honey marketers, but it is painfully obvious to beekeepers. We did enjoy booming growth, and now we are experiencing the beginnings of a very unenjoyable bust. The reason is because that growth was rampant and uncontrolled. The industry was overwhelmed with a 'gold fever', and in our madness, colony numbers grew far beyond what was sustainable, beekeeper behaviour degraded to the point where the 'wild west' analogies were totally accurate, and all of us should have been totally embarrassed by our behaviours when it came to the ruthless way we hunted down sites- we could only sleep at night because we told ourselves that others have done the same to us, so we can do it to them. The industry isn't in it's death throws, it will survive, but a lot of beekeepers won't.
  12. It is a madness- that is almost twice as many colonies as there are in Australia, and 200,000 more colonies then there are in all of Canada!
  13. We all knew things were unsustainable, and we all knew that the crazy, unregulated, rampant increase in hive numbers was leading us to disaster, but the speed and severity of the downfall is eye-watering! Day by day it feels more and more apocalyptic.
  14. Any word back from MPI on those results???
