  1. Honey bees are tuned in to the social culture of the hive as larvae, becoming more or less aggressive depending on who raises them, researchers have found. University of Illinois entomology professor and Carl R Woese institute for genomic biology director Gene Robinson, who led the research with postdoctoral researcher Clare Rittschof and Pennsylvania state university professor Christina Grozinger studied very young bees that were weeks away from adulthood. "In a previous study, we cross-fostered adult bees from gentle colonies into more aggressive colonies and vice versa, and then we
  2. I think they are actually putting something on to the surface. I have a few hive boxes which have not been painted and after the bees wash board them water does not stick to that area when it rains. I think its a way of keeping the entrance clear of water. Maybe useful when bees live in tree trunks and other areas.
  3. Do they show any difference in hive size or behavior between the slim ones and fat ones? Any difference in propolis use etc?
  4. Couple of Black Carniolan queens. You could still end up with a bit of bronze color in the daughter queens when grafting from these queens and you can get a pure black queen also when grafting from a Bronze Carniolan queen.
  5. One of the best queens I had was a small one. Looked rather slim too. But was able to lay an excellent pattern and fill the brood nest up. I think queen size and shape has a lot to do with genetics too.
  6. I have heard that AMM drones produce more Sperm per drone. I am not sure if that is a proven fact. There is some research o suggest that Queens do select on which sperms to use at what time. https://www.cals.ncsu.edu/entomology/apiculture/pdfs/DeGrandi-Hoffman_et.al.2003 copy.pdf DeGrandi-Hoffman_et.al.2003 copy.pdf DeGrandi-Hoffman_et.al.2003 copy.pdf
  7. Would it not be good to find out if we can actually select for lines of queens to actually mate with more drones which increases diversity in the colony there by improving general health of the colony? @Dave Black Weather conditions might play a part in how well the queen is mated but if we can get queens which mate with more than average drones in good weather then that could be a bonus.
  8. Was thinking if we can actually find out that one ecotype or a few lines of queens from certain breed of bees do actually mate with higher number of drones, then with some selection work and breeding we may be able to produce queens which will mate with higher than average number of drones in any weather condition. This could lead to a healthier bee population overall. I guess this could be a bit harder to find out than most other things though especially to determine sperm volume (queen has to die I think) and to get DNA from the paternal side in a hive to find out how many drones the que
  9. Do we know of any breed of bees which actually mate with more drones than the average number? As far as I know Italian and Carniolans mate with around 15 to 20 drones.

  15. No bumble bees were seen under this hive. I think its just the evening sun making the hive a bit too warm. [doublepost=1450219474,1450219364][/doublepost]The queen is uniform black color. The drones are also black. Just the bees show the black and white stripes.
  16. Some pictures of Carniolans bearding at the entrance. Not very clear ones though.
  17. I do buy a couple of queens from different sources every couple of years to add some diversity and to see how they differ from the other bees I have. I think 60 - 70 dollars are normal for a good queen from a reputable source. I use them as breeder queens once they have produced a few brood cycles. I also use a few of my own queens from previous season as breeder queens. So in a season I may graft and make between 50 to 75 queens from maybe 5 or 6 breeder queens. If the queen is reared properly and mated in a closed mating station which is saturated with drones of the breeders choice,
  18. If you keep young queens of any breed, they don't seem to swarm that year. But if the colony is crowded with no room they will swarm regardless of it being Carniolans or Italians. Personally I think both Italian and Carniolan queens do very well on their second year and don't usually have an issue with swarming even in the second year. Just that the management can be a bit different for both breeds and their hybrids. Some queens lay very well into their third year but they could become more inclined to swarm regardless of them being either race due to lower production of queen pheromon

  20. 2 swarms in Huntly and 3 swarms in Hamilton this week. All hived and doing well. One of the swarms was from my own hive and it had capped cells in it. While inspecting the hive the cells started hatching out. I have made six 3 frame nucs with them. Nice big virgin queens. Hope they get good weather to mate properly. Original queen had swarmed the day before which has been hived. Was a bit late to get to the hives this year due to being away on holidays.
  21. Nuc and Hive prices have definitely increased. I do sell a few nucs on trade me every year in spring and early summer(10 - 25 nucs) and I get a very good price for them. If I want to I could make up around 50 to 100 nucs in a season but that would take a lot more time and effort from me and all the nucs may not be at a standard I like them to be when I sell them. Hence I only make up a small number and make sure they are in very good condition when I sell them. The way I look at it is, market dictates the price for the nucs. If the price for honey stays this high (God knows for how l
  22. The way I see it we pretty much have every disease and pest in NZ except a few like EFB and Small hive beetle. Any new disease discovered in any part of the world seems to show up in NZ within a couple of year time. So we are either getting it into the country as an accident or somebody is bringing in bees or bee products or used equipments without permission. Thought we would have learnt from our mistakes when varroa got to NZ, but obviously not. What bee pest or bee disease has been found in NZ which was detected early enough to be eradicated by our so called biosecurity? With ille
  23. Is there any way of finding out if its a new illegal import? Like looking at the mitochondrial DNA or anything else? And if people are actually importing bees illegally and out bio security can do nothing about it, would it not be better to let people import bees with proper checks and quarantine procedures? It might help to stop illegal imports and at least we would be able to stop known diseases from entering the country.
