Nine polymorphic microsatellite DNA markers from the sorghum plant bug, Stenotus rubrovittatus, were isolated and characterized. These markers were used to analyse 22 individuals from a single field population. The number of alleles at these nine loci ranged from two to 28 (mean = 11.4) and heterozygosity ranged from 0.27 to 0.86 (mean = 0.58). Stenotus rubrovittatus has shown rapid population growth in the decades since the first report in the 1980s of serious damage to a rice crop. These microsatellite markers will be of value for studying both the population genetics and population dynamics of S. rubrovittatus.
