Microsatellite markers in a complex of <i>Horismenus sp.</i> (Hymenoptera: Eulophidae), parasitoids of bruchid beetles

Parasitoids of the genus <i>Horismenus</i> (Hymenoptera: Eulophidae) are the main natural enemies of bruchid beetles that feed on several species of <i>Phaseolus</i> beans. Samples of <i>Horismenus depressus</i>, <i>H. missouriensis</i> and <i>H. butcheri</i> were collected from seeds of three <i>Phaseolus</i> species throughout Mexico to examine the impact of plant variability on the genetic structure of parasitoid populations. For this purpose, six microsatellite loci were isolated and characterized. These loci are of great interest in understanding the taxonomy of the genus <i>Horismenus</i>, the most important Eulophid genus in the Neotropics.
