The genetic structure of the cotton bollworm, Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae), was studied in the eastern Mediterranean. Moths were sampled in six locations (five in Israel, and one in Turkey) and their genetic relationship was analysed using RAPD-PCR. Three 10-oligonucleotide primers revealed 84 presumptive polymorphic loci that were used to estimate population structure. Results reveal low level of genetic distances among Israeli and Turkish populations. The estimated values of F(ST) and θ for the eastern Mediterranean populations were very low across all populations, indicating a high level of gene flow. Four distinct RAPD-product profile types were defined, and fotmd in all Israeli and Turkish populations. Although no isolation by geographical distance was detected, topographical barriers may play a role in such isolation.
