Sometimes, the term VSH is used as meaning the same thing as varroa resistance. I think it’s helpful to clarify what VSH is. It is one of several resistance characteristics that affect the bees’ resistance to the Varroa mite. VSH
Before varroan came there could be seen occasional bees with undeveloped/deformed wings in spring. Maybe it was the influence of DWV, Deformed Wing Virus. But it may also have been chilled brood. During the final phase of the pupa development
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
I ended the last blog-post saying that the season wasn’t completely over yet. That was very true. August has been our summer here in Sweden. And it’s not over yet, August and warm summer. Though the nights are chilly. But
I make notes. I’m sure you do to. How much is a good question. I made more notes as a beginner and quite some years after that. When I got well above hundred hives I began to question each kind
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
I have prepared for and selected for varroaresistance for quite some years. Last year I learned how to test a colony for VSH, a simplified method described by John Harbo, easy for everyone to use. DWV-bees on the hardboard Before
Bees visit corn for pollen, period. Bees visit canola for pollen. Bees visit potatoes for pollen (Danish tests). Bees visit a lot of flowers for pollen. Bees get what the pollen is enriched with. Neonics are not good for bees.
One of the most important parts in my management system has become a simple thin hardboard in front of the entrance. The first thing I do when I come to an apiary is going reading them. They give a lot
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
