[Geographical variability and subpopulational genetic organization of oak leafroller moth]

Geographically distant populations of oak leafroller moth (Tortrix viridana L.) were characterized by the frequency uniformity for most often alleles and differentiation for rare ones in the esterase and protease loci. Opposite tendency was observed at the subpopulational level. It was supposed that the distinctive spatial distribution of the often and rare alleles was due to different sensitivity of the given groups to the factors of a dynamics. Natural selection and stochastic processes play a major role in the dynamics of often and rare alleles, respectively.
