| Abstract: | Thirteen polymorphic microsatellite loci suitable for population genetic studies of Helicoverpa zea were discovered by screening partial genomic libraries enriched for microsatellite sequences. Insects collected (N = 96) in Stoneville, Mississippi were used to characterize these markers. The observed and effective number of alleles per locus ranged from two to nine (average 4.46) and from 1.07 to 2.45 (average 1.81), respectively. Fisher exact tests detected significant deviations from Hardy–Weinberg equilibrium at three loci, probably due to inbreeding, null alleles, or Wahlund's effect. Significant genotypic disequilibrium was not detected between any pair of loci. |
