Another observation related to the previous string which brings it all to the more real world and practical. As one would expect, the further away from the original source of active selection, monitoring and maintenance of colonies with high levels of VSH, expect poorer performance regarding mites. A dilution of sorts happens with time, distance and decreased dedication to the custody of the original material. Also, from limited observations and comments, different geographies or beekeeping situations do not affect the performance vis a vis mites as long as the material is relatively close genetically to the original. So in that sense, IId queens produce the most mite resistant colonies, direct supersedures of those, likely mated in an environment with a preponderance of good drones are good, less if most drones are not resistant, and drifting into the not useful after each further generation of queens and larger dilution of drones. So it is possible to go after an advertisement of VSH queens that could easily fall into the latter category and provide no measurable value, while the advertisement might be more or less correct.
