Sažetak
Colorado potato beetle, CPB, (Leptinotarsa decemlineata Say) is the most important potato pest. Over the past 60 years, more than 300 cases of CPB resistance to 56 active ingredients have been detected in potato-growing regions of the world. Understanding population structure, gene flow, and variability is particularly important for CPB management because insecticide resistance is widespread in this species. A detailed genomic description could potentially give us an answer to genetically driven population evolution, which is often related to the evolution of resistance. Therefore, in our study, we used single nucleotide polymorphism markers (SNPs) and geometric morphometric (GM) methods to investigate the population structure and variability of CPB populations. We used 16 CPB populations from the main potato growing areas in continental Croatia. In addition, the morphology of hindwings of the same CPB individuals was studied using geometric morphometric techniques based on vein patterns. Regardless of the low genetic structure found in all CBP populations without significant variability, a single panmictic population or genetic cluster has emerged that characterizes CPB in Croatia. This suggests that control practices are successfully reducing genetic diversity, genetic structure, differentiation, and gene flow, and thus ultimately reducing the potential for the development of mutations associated with CPB resistance.
