  1. DWV seen 3 months after Apivar came out

    Assuming the hive has low varroa numbers. Then is a good idea to requeen with a more virus tolerant queen. Nowadays is best if the varroa numbers are kept at low levels at all times. DWV can accumulate in the combs (and evolve. Every replication is inexact copy) to the point that ones varroa do it's job , it may no longer needs it to cause clinical symptoms. There already may be enough nosema and other opportunistic infections to cause crawling bees. If a hive for some reason becomes too infested, I find it necessary to do nosema treatment alongside the varroa knockdown. The miticides are not a cure and should be applied only when necessary. They have an impact to the bee health as well. (Flumetrin and fluvalinate residues increase the DWV titers in non infested larvae)
  2. Mated queens disappearing

    I've came across this problem for a first time seven years ago. My advise is to use different breeder queen for grafting. The antibiotics doesn't help, neither shookswarming. Good record keeping is essential. Bees and brood taken from some hives constantly gave problems if used for making nucs (slow build up, missing queens, defective queens - usually crippled leg etc). I've had one occasion the queen being supersceded 3 times for one season. The first few years was most contageous (a jar of honey could knock down a whole apiary), then it became less of nuisance The most prolific queens (pale yellow) were the ones having defects (missing or ceasing laying) most often.
  3. Newly marked Q being balled

    The fact that the queen is mated and laying is not equal to fully sexually mature queen. Up to 3 weeks after the mating the estrogen levels are still rising ( similar to puberty in humans) and the egg laying rate gradually increases. The newly mated queens are still nervous and they are the ones who initiate the fight. Sometimes upon harvesting they fall into a cataleptic shock. Never seen a "tested" queen or virgin to do that. There was an Aussie paper investigating the correlation between the age of the queen upon harvesting and the introduction success rate. Somehow got covered in dust.
  4. Lyson gear

    From one Chinese manufacturer YES, to both first two questions. Back in 2010 for the first time. But the good product market and sells itself and if I am lying, my opinion of a forum troll won't matter anyway.
  5. Breeder queens

    Thanks for the participation. Anybody thought about the invention of the sugar? "Survival of the fittest" have different meaning now, having nothing to do with things like climate adapted or high vitality. If I didn't knew that conservation is often difficult even with Artificial insemination and island matings, maybe I would also believe in the open mating way.
  6. Carniolan queen, bees and brood

    I don't know all the answers, but when two lines are crossed (which is done once in every 3 Gen) that creates variation. The extreme yellow ones tend to make more brood ( like Italians) The extreme dark ones are usually thrifty and hot ( resembling other ancestor - Cecropia)
  7. Carniolan queen, bees and brood

    Nah, they are all different. US Italians, South American Italians, Scandinavian Italians, Chinese Italians, Italian Italians.... and so on. One of the best pure ligustica (if such thing exists) I had, was foraging in light rain and were always the first go out in the morning. One winter they were bringing in pollen during snowing day. Nothing like the typical WWII bomber aircrafts like some of the Italians.
  8. Carniolan queen, bees and brood

    According to some, there are four carniolan types: Black (Germany and Austria) Grey (Slovenia, Slovakia, Croatia, etc) Yellow (the Banat bee, some parts of Albania) Brown (Cecropia/Macedonica) The external uniformity is not a natural state but a result of the selection. Sklenar still has high frequency of one orange tergite on the workers.
  9. Breeder queens

    I don't think anyone in the world would disagree with a statement that said. We all argue about the details. But it is easier to say than actually do it. BTW. Does anybody knows the single turning point event in the honey bee evolution?
  10. Hi Paul, A1) Silly question. Yes, of course. A2) quick googling. Found this: Haven't read all the posts (too lazy for that). A3) Can't think of any. A4) YES. Absolutely necessary. All the supers should be placed in between ( until someone disproves otherwise) A5) I don't know. But keep in mind that after the last flow one of the queens usually disappear. And the amount of honey to my experience is less than what you would get from 2 separate hives, but more than one queen hive. Useful for early flows, with bees with slow spring development.
  11. Carniolan queen, bees and brood

    Ever heard of genetic linkage? Simple answer is YES. http://www.pedigreeapis.org/biblio/artcl/JHacarABJ91en.html In Buckfast breeding we see genetic linkages every day and sometimes the gut feeling saves time.
  12. Which to buy - Jenter or Nicot

    I suppose you used saliva for the #000 brush. It is said that the saliva increase the rejected grafts. The best grafting tool I am aware of is the Swiss one (not it's Chinese imitation) The Chinese grafting tool (with the bamboo pusher) is also good, doesn't require a sharp eye, but it is much slower than the Swiss one. I have an issues with the authority persons. Even the most erudite one sometimes speaks complete nonsense (don't ask me how I know that) As far as I know there are two models of Jenter. The one allows to pick up every second bottom in the row at once. So which one your mentor has in mind? The idea of Jenter is stolen from a plastic fondation with some removable bottoms from the Balkans in the middle of the '80s, whereas the idea for the removable cups, as far as I've been told, is a Russian patent. Nicot has one Turkish replicate ( same for eziqueen) and I hear now - one Chinese as well, and at least one imitation (45 cups). They all work differently. I've had such experience with carniolan type of bees. When the cups were not had been placed in a hive before the grafting - complete disaster. Never had the same issues with Italian type of bees. In the European countries where the queen rearer has a choice, Carnica is seldom used in the queen rearing. It makes it more difficult.
  13. Musings on waxed hive interiors

    Apart from the above-mentioned reasons, the beeswax is a organic fat and is still a medium for fungi (doesn't stop rotting), whereas the paraffin is non organic fat. Paraffin wax has much shallow penetration than the beeswax, so it is usually mixed with the more expensive microcrystalline wax at 50:50 ratio
  14. Breeder queens

    I no longer want to save the whole world, most people like it the way it is. I've never sold a single breeder queen. Fist, I find it EXTREMELY dumb idea. Second, it makes the queen rearers lazy, always relying on somebody else to do the hard work for them. Both sides lose in a long run. One of the 4 inbred lines used in the Starline program was actually a Carnica, bred for yellow colour (acording to Larry Connor, the successor of G. Cale) . Used to counterbalance the extreme brooding of the Italians. Practically “stability" is nothing more than certain level of homozygosity. Everything with inbr coefficient around 0,5 and above is considered “stable”. Stable hybrid is one thing, but making it a a productive one requires also modulating the allelic frequencies It is a common obstacle of ALL controlled mating programs. The bee no matter what still is a wild animal. I will keep my mouth shut on this. The only way to get the best results is to have: 1)good forage 2)bee a good beekeeper 3)use superior bees ( without bees, the hive is just a box) Bees are just animals controlled by instincts. We can change those instincts and even silence them. It is a way to make them doing what we want without the need to do it ourselves. Yes, we can skip the selection. We can use crappy bees and still be profitable. We can achieve the same results by applying more human hours. And we can also get the same net profits by having a higher number of hives. Some people prefer the NASA suits rather wearing a T-shirt and flip-flops. That’s another way of solving the same problems, which also works.
  15. Which to buy - Jenter or Nicot

    Why not Eziqueen? It is NZ made and has 4x more beds than either of the two. Very usefull for royal jelly production. But from the two I would say Nicot. Less parts, plus the cells (disposable) and the cell holders can still be used for grafting if you change your mind. The flipside is that one cassete is needed for each breeder ( e.g. for 500 hives about 10 breeders should be used) and is not very sanitary to move the cassete from one breeder to another ( those queens are expensive)
