Genetic structure of populations of Ochlerototus dorsalls (Meigen, 1830) (Diptera: Culicidae)

V Milankov·, Lj Vapa
Allozyme variability at nine loci of Pa1aearctic and Nearctic populations of Dchlerotatus dorsalis was detennined. Estimates of genetic variability showed that the Palaearctic population ranked higher than the Nearctic population in percentage of polymorphic loci (P: 0.77; 0.33), the mean number of alleles per locus (A: 3.3; 1.8) and value of mean heterozygosity (Ho: 0.263; 0.059). In addition to the lack of identical alleles at Est-6 locus, genetic differentiation of Palaearctic and Nearctic
