  1. Robbing set in this afternoon so I've closed them down for good. Wrap and freeze boxes then wait for the results. The MPI expert sent me some info on a CBPV clinical trial. There's a note that says similar symptoms may be observed following low level exposure to fipronil. Food for thought.
  2. I was of a similar opinion. But reading suggests there are two distinct manifestations of CBPV. In young bees their morphology is changing and the virus interferes with development. They take on a hairless, greasy appearance, they tremble and die in or near the hive. Older bees tremble and their flight muscles are compromised. They display the k-wing symptom and typically die meters from the hive entrance while heading out to forage. The onset of the virus for individual bees is apparently very quick - hours rather than days. The k-wing bees may look healthy because they were healthy a short time previous. The last time I saw CBPV the majority of bees affected were younger bees. When I look back at photos I can find k-wing but only in small numbers. I didn't notice them at the time. This time I haven't noticed any hairless, greasy looking bees. Maybe this is a different variant of the virus that affects older bees. Indeed many of the bees crawling in the grass are very old with significant wear to the trailing edges of wings. Early afternoon, the entrance almost looked normal as younger, evidently unaffected, bees took orientation flights. Results of samples will be interesting.
  3. MPI agent came by this morning to collect samples. Indeed some are bound for Auckland for tracheal mite analysis. The others are bound for Wallaceville for virology analysis. There is now clear evidence of trembling which is symptomatic of CBPV. Much less pronounced than I recall it but trembling for sure. So another vote for CBPV and reduced likelihood of TM.
  4. Call back came within about 10min. Coming tomorrow morning to collect samples for analysis. I'll post follow up when available @john berry @David Yanke
  5. Neither do they exhibit the classic tremble that goes with CBPV. I've reported to MPI and expect a call back from a specialist in the next day or so.
  6. Hopefully this isn't what it looks like. I need to cast the net as wide as I can. A little less concerned now. The Beekeeper's Handbook By Diana Sammataro, Alphonse Avitabile, page 136, describes K-wing as a possible symptom of type I CPV and of tracheal mites independently.
  7. Would anyone care to share their experience of K-wing either locally or overseas? Large numbers of bees with splayed wings, unable to fly. In last 24hrs the degree of splay has increased to what you see in the photo. This matches photos I've seen from overseas that we're reported to be K-wing due to tracheal mites. Tracheal mites haven't been found in NZ so this may be some other disease. I've taken a sample of affected bees and will contact the agency for guidance. Meanwhile, I'm keen to understand more about what this might be.
  8. @M4tt I've seen this before. It'll be archived here somewhere. I came to understand that CBPV is passed from the queen to brood via the egg. Requeening with resource from outside the colony cleared it up within a few months. In spring the colony will require close monitoring as its foraging force will be greatly diminished. This one
  9. Feral bees? When managed bees evolve tolerance for varroa then we might see feral bees. I would focus on managed bees not feral.
  10. Yes, but the problem would be proving it. Linking the loss directly to the offender.
  11. I've trialled double queen hives as FD QE FD QE then supers. They don't appear to fight through a single excluder.
  12. I inspected one recently. Five frame FD NUC transfered into a ten frame box. Bees doing really well and no disease. I despaired at the state of the brood frames sold to this poor beginner. Munted comb, loads of drone brood. Clearly culled frames flogged off to the first sucker to come along. Clearly no pride taken in the quality of the NUC. Fortunately the beek has joined our club and will get support to cycle those frames out quickly.
  13. Just catching up on this. Great reporting. Very interesting reading. Just a thought regards robbing. You described these hives as strong and yet they were robbed. Strong hives don't tend to get robbed. If you were inexperienced I'd suggest you had over estimated their strength. You're not inexperienced so perhaps something else is going on. Maybe the defining trait in these bees is low aggression. If they are less inclined to rob other hives then their opportunity to bring varroa back to the colony is also less. With fewer new varroa arriving the viral load on the colony should be more stable and the bees' better able to fight off infection. Lower agression might also mean less likely to defend themselves and consequently more likely to be robbed. Just thoughts. Unqualified thoughts at that.
  14. Proximity to competing apiaries also has a massive effect on crop.
  15. Same as anything else that is abandoned on public land. Eventually the regional authority contracts someone to remove and dispose. They may seek cost recovery if the owners can be identified.
  16. The rule should apply differently when the hives are abandoned. Consider if someone establishes a maimai on your property with permission then abandons it later. You're not obliged to leave it there indefinitely until they come back to remove it. They cede ownership when they abandon it. You don't like it, you tear it down, end of. If the landowner has made reasonable attempt to have the hives maintained or removed but the owner refuses then they are abandoned. They become property of the landowner for destruction or disposal as they see fit. In law I expect there are some formal notifications but regardless you can't leave stuff on someone else's property indefinitely without permission.
  17. I don't aspire to be an AP2 because I don't expect to acquire the experience to be credible inspecting commercial hives. It shouldn't matter, but to me it does.
  18. It's all on the AFB website in the menu under policy documents. http://www.afb.org.nz/Websites/nzafb/images/AFB Policy 001A.pdf
  19. I'm not implying anything. I thought AP2s were few in number and usually semi-retired commercials. You suggested that "most commercials" are AP2s. That implies to me a much larger number drawn from a pool of very busy beekeepers. Although I'd be surprised if many AP2s hadn't done time as a commercial beekeeper at some point in their careers.
  20. I would have thought most commercials are too busy to be AP2s. Shows how little I know. Great news if they're finally getting AP2 numbers up.
  21. As you pull each brood frame give it a half-shake. Field bees will take flight while nurse bees will hang on.
  22. Is there an interesting back-story to this post?
  23. Welcome to NZBees Phyllis. That's an interesting article. Overseas, I know they use antibiotics in beehives to manage foulbrood. We're forbidden to do that in New Zealand. I don't think that anyone would be tempted to use glyphosate for that purpose here.
