Re: Randy Oliver's September article on alcohol washes
I don't see "errors" mentioned until this line. IMO, Randy is not making any "errors". There are some weaknesses with his method. The question to ask is whether or not he will do something to tighten up the selection process. I am certain that other traits besides VSH are important with my bees. The path he is currently taking will identify colonies that maintain very low mite counts which should correlate with more than just VSH traits.
Well so far the errors Randy is supposed to be making illustrate the authors who claim these are errors do not understand his program.
If I had gone to the trouble of identifying @50 colonies that have very low mite counts, I would probably set them up in an isolation yard and manage them for a year to see how many maintain low counts through winter and into the next year. Then I would breed from the colonies with the lowest mite counts over an entire year. This would eliminate any colonies that are not truly mite resistant.
