Abstract: | Five microsatellite loci of Helicoverpa armigera were isolated from a partial genomic library screened by oligonucleotide probes. Primers were designed to detect allelic variability and heterozygosity in 60 individuals collected from different host species. All loci were found to be polymorphic, have 8–11 alleles with expected heterozygosity ranging from 0.81 to 0.88. Our results indicate that the five microsatellite loci could provide valuable markers for population genetic and ecological studies of the cotton bollworm. |
