    Bee Box Brander

    The branding plates are made of bronze (stays hot longer). Bit heavy for this kind of handle.

    lines of hybrid bees

    The local mongrel mix in Europe has Caucasian, one or two (out of 60+) lines of Carnica, few strains of Ligustica, Cypria, Carpathica, Anatoliaca, Armenian, Primorsky, Sahariensis, Monticola/Elgon + some relic genetics of native bees in it. And you dare claiming good genetic diversity for the NZ bees, holding only three sub-species of bees as a proof? WoW

    lines of hybrid bees

    Yes, introgressed genes always exist, even in the pure race "Nazi" Carnica line breeding programs in Austria and Germany. But even they rely on heterosis for their production hives. Ask a professional sports athlete IF he/she takes substances prohibited by the Anti-Doping Agency. - NO!, right. Is a Dingo dog a crossbred or a dog breed itself?

    Cell Spacings On Cell Bar

    Regarding preventing construction of brace comb over the cells, as mentioned above - having two foundations per batch of grafts in a finisher helps . Empty foundationless frame, even better, but still doesn't solve the problem completely. Things that work best are: Queenless finisher Putting the cell bars into a insulator frame (queen excluders) Hair roller cages over the capped cells (left open). Good for small scale queen rearing. Cells get ugly, but unaffected otherwise. About the spacing, believe this is the right one: Less space between cells does make them smaller, but more than this doesn't seem to make them any bigger.

    lines of hybrid bees

    Very interesting concept. Heterosis (invented term, standing for stimulated heterozygosis) is correlated with the level of heterogeneity. The degree of stability (homozygosity) is calculated by the inbreeding coefficient. Both are opposite and self excluding things. The only hybrid bees known to me are a result of the famous breeding program ran by Dadant for nearly half a century. Rest should be called (interracial/line) crosses (known parentage) or mongrels. Is it possible to stabilize a cross? - YES! Most dog breeds and todays non hybrid plant cultivars are created by crossing different dog strains and plant varieties (most of which do not exist anymore). Do they possess hybrid vigour? – NO. As for Buckfast, just like any other strain of bee, it gives best results when outcrossed. It is nothing more than a set of qualities/additive polygenic traits, holding on their dominance in open matings. Rest is heterosis. 439.full.pdf

    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)

    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.

    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.

    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.

    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.

    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)

    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.

    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.

    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?
  15. 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.
