Re: Riverderwent Survival Treatment Free 2017
BLUP based breeding programs are primarily focused on commercial traits. They are now shifting to include mite resistance. IMO, a day late and a dollar short, but definitely counters the statement that bees can't be bred.
Bees can't be bred. I don't think any level of infestation will result in acceptable results. Not when beekeepers attempt to calculate the cost of making wax and drone rearing in their bees. Any mites will be recognized as loses and considered unacceptable. Develop a resistant bee. it is destined to be rejected. Beekeepers want a bee with no mites.
There are plenty of mite resistant bees. The problem is that they are not yet developed for commercial use. Once they are, mite susceptible bees will be phased out. This will take another 10 to 20 years. As always, just my opinion.
