> After 8 years of very strong selective pressure, the prevalence of strongly-resistant colonies in our breeding population (now ~15%) has increased roughly 75-fold.
Assume that these colonies become the standard-issue bee in the USA due to their resistance being less nebulous than other attempts at breeding a "resistant bee" in the past.
If so, what happened as a result? The overall diversity of bees got reduced as a side effect, so there is less diversity, and more susceptibility to whatever pest of pathogen comes NEXT.
"Strong selective pressure" eliminates everything except the "strongly resistant" colonies, which throws out a whole bunch of babies with the bathwater.
