Characterization of microsatellite markers for the apicultural pest Varroa destructor (Acari: Varroidae) and its relatives

Sixteen microsatellite loci were isolated and characterized for Varroa destructor using two procedures to screen genomic libraries. Together with those previously designed, they provide useful markers for the study of this harmful apicultural pest whose populations on Apis mellifera are poorly variable. Observed variability has been expressed as the number of alleles because heterozygosity is only rarely present. The defined primers have been assayed on another species of the same genus (V. jacobsoni) and almost half of them successfully cross‐amplified and revealed polymorphism. These results suggest that the microsatellites isolated here should prove useful for population studies in different Varroa species.
