Eight microsatellite loci for the sexually transmitted, parasitic mite Coccipolipus hippodamiae

Seven dinucleotide and one trinucleotide polymorphic microsatellite loci were isolated from the mite Coccipolipus hippodamiae. This mite is an ectoparasite of coccinellid beetles (ladybirds), principally the European two-spot ladybird Adalia bipunctata, where it causes sterility in the female host. Levels of genetic diversity were assessed using 32 mites from Warsaw, Poland. We observed moderate variability, with the number of alleles per locus varying between 2 and 4, and observed and expected heterozygosities ranging from 0.031 to 0.267 and between 0.062 and 0.526, respectively. This is the first description of microsatellite loci from the genus Coccipolipus and these loci are currently being employed to answer fundamental questions about the epidemiology of C. hippodamiae infections on A. bipunctata.
