  1. The problem with the Queen Introductions into those 20 splits was almost certainly candy issue, and that places the blame with person who supplied the Queens. Candy should not go rock hard. Probably, there wasn't enough Inverted Sugar in the Candy. There is an art to making Candy, and it is important to get it right. Honey Candy is the most fool proof, you can err on the side of being too firm, and it will still pull enough moisture to keep it soft enough so as not to slow down the release of the Queen. Honey is so good because almost all the sugars in Honey have been inverted by the bees, and it is these simple sugars that give the Candy their hygroscopic properties which keep the Candy from going rock hard. Some people worry about the AFB risk from Honey Candy, but it is negligible, if not zero. The potential of getting an infective dose of AFB from the amount of Honey in the Candy must be close to zero, and in the candy making process if I am using Honey, I take the Honey to boiling point in the microwave(Carefully), and the boiling point of Honey would be well above the boiling point of water. When using Inverted Sugar, it is more important to get the Candy right, even though it is called Inverted Sugar Syrup, all the sugars are not completely Inverted, and because it is 67% Syrup, you are adding more icing sugar to get the firmness right, so the final percentage of Inverted Sugars is less than with Honey Candy, and therefore more prone to hardening. A little added Glycerine also helps keep the Candy soft. Candy that goes hard is a disaster for Queen Introductions. I always Introduce Queens as soon as I make the Unit Queenless, saves a second trip. With making up Splits, if they are going on top, introduce them straightaway, if you are transporting them, introduce straightaway after you drop them on their new site.
  2. Mostly it was one man, not NZ, and he was a transplanted Welshman, who did all the work, and I remember one Conference many moons ago when there was fierce opposition to a Remit at the AGM to approve a 25 cent per hive levy to to fund fund his research and the marketing around it. Up until that point you rarely heard the word Manuka used in NZ as well, Manuka and Kanuka were just referred to as Teatree or scrub.
  3. Nice try at putting a positive spin on the News Story, and your involvement in it. You were either very foolish, or very self-serving to let yourself get involved. There can be no positive spin put on that story- it was damaging, and has come at a time when we can least afford Own Goals.
  4. Those were the bad ole' days. Now most operators are very professional, and almost paranoid when it comes to spray drift because they know their business is at risk if they stuff up. They spend small fortunes on spray rigs and nozzles that control droplet size to help ensure that that the spray only goes where it is meant to go. Their GPS guidance shows exactly where they have sprayed and is accurate of less than a meter, and all that information is kept in case there is a complaint. I am only sticking up for them because they are not the problem here. Testing, and the people responsible for that News Item are the problem.
  5. There is proof that the contamination was intentional, but the culprits and the motives can only be guessed at.
  6. The problem isn't the 'Muppets' or 'Monkeys' carrying out the aerial spraying operations. They are professional contractors carrying out legit spraying operations on nearby farms to where the positive tests have been recorded. They are the same guys that lift your hives onto Heli sites, they certainly are not Muppets or Monkeys. In another incident a rival beekeeper/landowner in a territorial conflict lifted lids and contaminated honey boxes with glyphosate because they knew they tested for it. Except for that last instance, this is not a health issue, the levels being found are far below levels that could cause a risk to health, even if you ate several kilos of the contaminated honey at a sitting. The Problem is the Testing. The Testing Regime we are inflicted with now is insane. What's next- Tordon, Metsulfuron, the potential list is endless.
  7. I own red bands, and I know that glyphosate is a very good gorse killer. It is an amazing broad spectrum herbicide, but it is a useless insecticide. It is harmless to honey bees, and as has been stated it is the penetrant used with it that is hard on bees if they get hit directly by the spray. As I just said in another post, ironically, it is Glyphosate that is used with other chemicals to inhibit germination when establishing Manuka Plantations. The Glyphosate takes out the grasses, the Kanuka, the Manuka, and every other tree growing in the area pre-planting.
  8. One exception being the establishment of Manuka Plantations! Ironic
  9. CourierPost are all care and no responsibility. We have used them for decades, and generally they are an amazing service. We meet the Courier, most days during the shipping season, at Taipa in the Far North at 16:00, and 99% of the time they are with our Customers the next morning. But, if there is an issue, the most you can expect is a Replacement CourierPost Ticket, they never cover the cost of the Queens lost. We value the service, and understand if Beekeepers rock the boat too much, and demand them to cover the cost of the Queens lost(which they won't), then they will just stop carrying live bees. It is a very tiny part of their business, and they don't need the hassle. To help the Queens get through, safely and on time, make sure that they are packaged properly, and clearly identified as Live Bees. Do not stick them in Courier Bags or Envelopes.
  10. We have 3 Groups of Cell Builders, We graft every 3 Days, We work(move open brood above the excluder) the Group of Cell Builders 24 hours before the Graft. That means that for any particular Group, we get back to work it 8 Days after the previous Graft. It is just the most convenient time to have the Cells come out and go into the Incubator. I don't know this, but it might be best to leave the Cells alone after they are just sealed because there is a lot going on. The prepupa is busy spinning her cocoon, then stretching out and pupating. Might not be the best time to be bothering them with a move into the Incubator.
  11. Gets them out of the Cell Builders, gets them away from Rogue Virgins, actually saves having another group of cells builders. There is quite a bit of resonance from the fan! You can manipulate emergence time with temperature setting.
  12. With our Cell Building System, we graft every 3 days, cells go into the Incubator on Day 8 from grafting, and go out late on Day 10. We use Caricells to put cells out, but they are only plugged in on the way to the Nuc yards, don't mind the temp. dropping away as we put out cells, even if it takes an hour or so. We sometimes put cells out on the morning of Day 11, but sometimes during the season, or depending on the incubator setting, you can have the odd virgin hatch after lunch on Day 11. As for Incubator accuracy, Honey Bees have evolved to have very precise thermal regulation within the Brood Nest, there must be a reason, and if it is important to them, it is important to me.
  13. Sadly, I think Contherm might have closed down. Tried to also post a pic of the Incubator itself, but was told I had breached my 2Mb limit. Will try again
