Sažetak
The codling moth is an economic pest of apple production in Croatia and has a cosmopolitan distribution. We have been working on CM biology, ecology, and genetics for over a decade to better understand how this pest has only changed its distribution, abundance, and movement patterns and what this means for improving control practices and management of the species in Croatia. Our initial work commenced with a study into the biology and ecology of CM under different treatments. Our findings showed that in the untreated orchard, two generations of CMs were observed per year, whereas an additional third flight period of the moths was observed in the treated orchards. This work was followed by a population genetic study which showed no genetic differentiation was found. Our most recent work on CM population genetics using SNPs found evidence that population sub-structuring may be occurring as a result of improved integrated control practices in Croatian apple orchids over the last decade. To further investigate population sub-structuring we investigated phenotypic traits under selection (ie. wings) using geometric morphometric (GM) methods. GM methods showed a reliable pattern of differences related to the type of control practice CM was subjected to. The combined use of SNPs and GM to detect resistant variants is a completely new approach and provides new insights into CM control. Recent innovative methods we’ve undertaken involve the use of structural engineering numerical modeling using the finite element method (FEM) to investigate the dispersal capabilities of CM in Croatia by modeling wing deformation against different wind speed moths experienced in the field. Our findings showed CM from the ecological orchards displayed the least wing deformation as the wind speed increased and had the most structurally sound wings compared to CM from integrated control orchids that had wings that were less structurally sound.
