Re: something to think about
In regard to mite pressure. What pressure do you consider would be necessary to see colonies actually improve in regard to mite resistance? With pressure being defined as the percentage of bees that show adequate improvement? I suppose in regard to treatment free this would be the percentage of hive that survive regardless if mite infestation without treatments.
Quoted from Michael above.
"Breeding for any one trait in my observation of human breeding programs, has almost always failed in the long run."
Are you saying this in regard to bees or breeding of animals as a whole? I agree that breeding of bees has not produced the same results as other animals.
Significant Minority vs Insignificant Majority, 20% of causes produce 80% of the effects.
