One mite from 300 bees. I understand that sometimes it’s a good idea to get an idea of the infestation level of varroa mites in bee colonies. You can take samples from a couple of colonies in an apiary to
The bee shaker and varroa resistance
More viruses due to cold weather
The weather has given the coldest May since 1962, 12 years before I started with bees. The bees have had a hard time getting enough pollen to keep up egglaying to reach optimum nectar gathering strength when summer comes. In
Varroa feces, larval and pupal skins
I found a good description of what happens in the brood cell here: http://www.ars.usda.gov/Research/docs.ht…44&page=14 There are good pictures of different stages in the development of the bee and of mite reproduction. There I also find the answer to my question and
Varroa defecation and pupa remains
I’m checking my, as I think, most promising colonies for the VSH trait. (http://www.elgon.es/diary/?p=146) After dragging out more than 1000 pupae I have learned a lot about analyzing what I see. But I understand it’s more to learn. And I’m
MT-colony conclusion
I have shared the performance of this colony which had almost a box of plastic small cell frames and natural positioning of these frames (as the uppermost broodbox). Which also had a tough experience with mice living in the bottom
Europe versus USA: breeding varroa resistence
Rüdiger Dietrich’s comment is so good I made it into a post of its own as well. Thanks Rüdiger! As a German I have of course to answer to Eriks contribution “Breeding for Varroa resistance: Germany versus USA”…:-). When commenting
Breeding varroa resistence: Germany versus USA
The other day I received Imkerfreund 12-2013 in my postbox. In this issue of the German bee magazine I found an interview with the scientist leading a varroa breeding project involving beekeepers. It’s a project that has made some progress.
Efforts for resistant bees give results
I really work for getting bees that can handel the varroa mite themselves. You get results when you do, but it’s extra work and sometimes it’s difficult to interpret what you see. And you loose some bad bees. And some
The art of beekeeping
Hive of eccentricbeekeeper.com Foundationless Of course it’s more natural for bees to build their own combs. But is it the best for bees and beekeepers? There’s been a lot of discussion about natural beekeeping. First let us be clear. Natural
Searching for resistant bees
Kenya I started long before the mite arrived to focus on increasing the varroa resistance in my stock. 1989 I went to the mountains of Kenya to get genetic material that were more related to the resistant bees in South
