[QUOTE="John B, post: 13318, member: 207"] Melissa's presentation was fascinating. Always remembering that conditions are very different in Norway , basically Melissa went to Norway to study a beekeepers hives they had not been treated for nearly 20 years (buckfast) and she then tried to find and breed the same resistance traits in carniolains. This has been done successfully. The resistant bees uncapp and re-capp the brood sometimes multiple times and the best hives are the ones that do this the most accurately i.e. find the varoa.These bees do not remove the brood. It is unclear why this results in varoa control but there appears to be more than enough evidence that it works. All of this is done by selection and then natural mating rather than AI. I would have to study Melissa's findings a lot more to be able to answer every question but you can see this type of uncapping\capping in New Zealand once you know what to look for and I saw it yesterday in my better bee Queen. This type of resistance has been found in multiple other countries. It will be in New Zealand but because it doesn't seeem to be found in drone brood it may not control varoa sufficiently here but it would definitely help keeping hives healthy and alive. [/QUOTE]

What type of honey is New Zealand famous for?
