The Beach Scale, Cryptococcus fagisuga, an invasive European species, devastates stands of native beech throughout the northeast, producing lesions recognized as Beach Bark Disease (BBD). This species is understood to be parthenogenic and preliminary genetic analyses of ITS regions have shown no variation between populations in Europe and North America. Damage from the scale infestation allows in a cascade of fungal pathogens and other invasive parasites, leading to death or natural destruction of the tree. Mortality of the tree can occur in as little as two years after infestation and only about 1-5% of trees in a given stand are resistant to scale invasion. Historic logging practices have left northeastern forests with a higher than natural composition of beech, facilitating the spread of the scale. Biological control is recognized as the most likely management approach. In the search for historic locations of the scale which may reveal native predators or parasitoids, we use a “genomic fingerprinting” technique, AFLPs (Amplified Fragment Length Polymorphisms) to investigate fine scale genomic variation and generate an intra-species phylogeny suggesting geographic origins for the species and explore the possibility of cryptic sex in these supposed parthenogens.
