Abstract

We describe six polymorphic, trinucleotide microsatellite loci that were isolated from the yellow dung fly Scathophaga stercoraria (Diptera: Scathophagidae), a model system for examining the mechanisms behind sperm competition in species with internal fertilization. These microsatellites yielded between 3 and 11 alleles per locus in a sample of 20–48 dung flies collected from several sites in Cheshire, UK. Observed and expected heterozygosities varied between 0.195 and 0.900 and 0.335–0.842, respectively. These markers should allow us to investigate postcopulatory sexual selection processes in this fly much more fully than has been possible in the past.
