Sažetak
The western corn rootworm, Diabrotica virgifera virgifera LeConte, (WCR) is economically the most important pest of maize in Croatia. First occurrence of WCR in Europe was in 1992 near Surčin, Serbia. Till nowadays different monitoring techniques have been conducted in Croatia to define and predict WCR population abundance and variations through all invasion phases. Traditional population metric surveys were conducted in first years of WCR invasion in Croatia with the aim to define population abundance and dispersal. Later a modern monitoring technique such as population genetics (using microsatellite markers) was used to provide information on population variations within and among WCR populations in Croatia and its neighboring countries. To better understand WCR invasion process and to define the impact that this invasive species have on global agriculture production and food resources during the next few years we will use a single nucleotide polymorphisms (SNPs) method. SNPs are single base substitutions found at a single genomic locus. For use in population genetics, SNPs have surpassed microsatellites as the marker of choice. Compared with microsatellite loci SNPs have lower allele diversity and provide less statistical power to discriminate unique genotypes but have a denser and uniform distribution within genomes which make them useful for population and mapping studies. Furthermore, SNPs has become an affordable and readily accessible means of generating important data on a species. During my PhD thesis investigation we will use SNPs on total WCR populations from invaded area in Croatia as well as populations from most infected regions in U.S. with the main purpose to establish detail genomic description of this invasive species. WCR in last decade in its native region in U.S. developed resistance on all control measures. Considering ongoing multiple introductions from U.S. to Europe, which was proved in many surveys, the resistance could become serious problem in Croatia and Europe as well. Detail genomic description could give us an answer about resistance which is probably genetically conditioned. Considering this our aim will be to find genetic marker which could be used in detection of resistance pattern in WCR.
