Screening and microsatellite data for Varroa infesting resistant honey bee pupae

We investigated how the evolution of host resistance could affect the
infesting population of Varroa mites. We screened a Varroa-resistant honey
bee population near Toulouse, France, for a Varroa resistance trait: the
inhibition of Varroa's reproduction in drone pupae. We then genotyped
Varroa which had co-infested a cell using microsatellites. Across all
resistant honey bee colonies, Varroa's reproductive success was
significantly higher in co-infested cells but the distribution of Varroa
between singly and multiply infested cells was not different from random.
While there was a trend for increased reproductive success when Varroa of
differing haplotypes co-infested a cell, this was not significant. This
dataset may be useful to anybody interested in the evolution of
host-resistance on the parasitic mite Varroa destructor. There were no
legal or ethical considerations associated with this study.
