Isolation and characterization of polymorphic microsatellites in the groundnut seed beetle, Caryedon serratus (Coleoptera, Bruchidae)

Caryedon serratus feeds on the seeds of four genera of wild Caesalpinioideae. It recently became a major pest of groundnut in Africa. To determine the extent of gene flow and isolation between wild and groundnut-feeding populations, we isolated and characterized 10 microsatellite loci in this species. Polymorphism ranged from three to 15 alleles in the 80 individuals collected in four localities in Senegal on five host plants.
