Sažetak
The gypsy moth (Lymantria dispar) is a folivorous lepidopteran species domestic to Europe, where it has characteristic periodic outbreaks. Due to its polyphagous nature and capabilities for longitudinal and latitudinal expansion it is considered as one of the significant biological agents causing economical and ecological damage in forests of Europe. The variation in outbreak periodicity between continental and mediterranean regions of Europe prompts the hypothesis of possible genetic differences between populations, supported by the known consequences of quaternary glaciations. Prediction of northward range shift due to climate change, as well as ever-growing risk of anthropogenic movement, increase the chance of migration of formerly isolated southern populations. Using the COI mitochondrial DNA marker, 497 specimens from 38 sites in Europe were analyzed. Recolonization pattern of gypsy moth is congruent with the butterfly paradigm and Dinarid Alps acted as a barrier for the Illyrian genes. Allelic richness index (r), as well as migration index (M) based on genetic divergence between populations were assessed, and subsequently visualized with Genetic Landscape toolbox. Data from future monitoring programs can be incorporated into this base dataset to perceive changes in the migration index, an indicatorof the migration rate between populations.
