Resistance traits – VSH, VSHD, Grooming and more

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

Keeping track of the infestation level

In the search for breeders for this season I tested a number of hives for the infestation level of Varroa mites in the beginning of May. Those choosen had not been treated for mites either not at all last season,

Cory Stevens lives in southeast Missouri. There are some hives of hobbyists some miles from him. A larger beekeeper is 7-8 miles from him, but he uses Cory Stevens’ queen cells.  The whole Stevens family works together Started with resistance

The bee shaker and varroa resistance

The bee shaker and varroa resistance

 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

Changing plans

Changing plans

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

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

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

Small cells and VSH

Small cells and VSH

There have been numerous tests of varroa reproduction with bees on different cellsizes throughout the years, with the assumption that you then test varroa resistance. As far as I understand that can be true, but you don’t know to what

My selection parameters

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
