    Characterization of Simple Sequence Repeats in Phormia Regina Miegen (Diptera: Callphoridae)
    (2024-08) Waletzko, Cassandra; Picard, Christine; Walsh, Susan; Owings, Charity
    Phormia regina Meigen is a forensically relevant species of blow fly, common in North America and used to estimate the minimum postmortem interval in forensic casework. It is also possible to use blow flies to survey the environment for biotic and abiotic information drawn from both larval and adult stages. There are both forensic and environmental uses for genetic analysis of blow flies. Blow fly kinship is especially useful for detecting postmortem movement of a corpse or to assess abundance of carrion in a given location. To test genetic relationships between individuals, discriminatory loci such as microsatellites, or polymorphic tandemly repeated sequences of DNA are necessary. Here, we characterize novel microsatellites generated from the genome of P. regina. Thirty-four candidate polymorphic loci with conserved flanking regions, have been isolated. To date, seven are heterozygous and polymorphic testing in two lab populations and one wild population. The simple sequence repeats characterized here complement existing loci (N = 6) for greater discrimination for testing relationships between individual flies.
