Re: Breeding the good mite
From post #8 reference 1; " At the phenotypic level, there is known variation among Varroa haplotype groups and species in their ability to successfully parasitize A. mellifera [16,17], as well as known variation in the resistance of honey bee strains [14,15,54,55]."
While I do not doupt that colapse is a primary mode of dispersal, I find it illogical that it is the sole dispersal mode. A mite line that does not kill, but survives for a longer time has the potential to distribute an equal # of genes at a slower rate through drift.
Isolation and reduced drift has to be a significant survival benefit for ferals. ( And aan inverse factor for commercials)
Question; How common is mite drift through adult drones?
