We have revealed patterns in the geographic distribution of Hessian fly populations with respect to mitochondrial markers probably due to bottle necks and/or founder effects during dispersal. In addition to mitochondrial markers an 829 bp intron in the Hessian fly ortholog of the Drosophila white gene has been added to the analyses to provide for more robust phylogenetic reconstruction and analysis of population history. Regions of interface between the geographic boundaries of mitotypes in North America could be sites of interest for collection of populations over time to evaluate the rate of appearance of new biotypes.
