Technical Abstract: Mitochondrial and nuclear markers were used to assess the phylogenetic relationships between introduced North American and native Old World populations of Hessian fly (Mayetiola destructor), one of the most common destructive pests of wheat found throughout the world. Domain III of the mitochondrial 12S rRNA gene and intron 1 from a Hessian fly ortholog of Drosophila white were sequenced from seventeen populations across North America, Southern Europe, North Africa, and Southwest Asia. The key focus of this project is to further establish relationships within and between populations of Hessian fly in the United States in comparison with those abroad. This will allow for an assessment of species-wide genetic diversity that can be used to characterize the potential for the future rise of virulence alleles in the United States and will allow for testing of the single introduction into North America hypothesis.
