Western honeybee populations, Apis mellifera, in Europe have been known to survive infestations of the ectoparasitic mite, Varroa destructor, by means of natural selection. Proposed mechanisms in literature have been focused on the management of this parasite, however literature remains scare on the differences in viral ecology between colonies that have adapted to V. destructor and those that are consistently treated for it. Samples were collected from both a mite-surviving and a sympatric mite-susceptible honeybee population in Norway. The prevalence and abundances of 10 viruses, vectored by the parasite or not, were investigated in adult host workers and pupae as well as in V. destructor mites. Here we show that the mite-vectored Deformed wing virus (DWV-A) is often lower in both abundance and prevalence in the mite-surviving population in tandem with lower phoretic mite infestations compared to the mite susceptible population. However, the non-mite-vectored Black queen cell virus (BQCV), had both a higher abundance and prevalence in the mite-surviving population compared to the susceptible population. The data therefore suggest that general adaptations to virus infections may be unlikely to explain colony survival. Instead, mechanisms suppressing mite reproduction and therefore the impact seem to be more important.
