Abstract

We developed thirteen microsatellite markers for the stonefly Brachytpera braueri, a rare aquatic insect. We compared a “traditional” approach yielding an enriched library by cloning of positive host cells, hybridising and Sanger sequencing of target fragments with a 454 next generation sequencing approach. From a total of 881 fragments containing a repeat motif thirteen polymorphic loci were developed and tested for two populations. Number of alleles ranged from 4 to 20 and values of heterozygosity varied from 0.17 to 0.91 (HO) and 0.26 to 0.91 (HE). The markers are essential to investigate the colonisation potential of freshwater insects.
