title: The use of mitochondrial cytochrome oxidase I gene (COI) to differentiate two UK blowfly species -- Calliphora vicina and Calliphora vomitoria.
abstract: Traditionally identification of forensically important insects has been carried out based upon morphological differences between species. However insect evidence found at a crime scene may on occasion be difficult to distinguish by morphological techniques and under these circumstances another method of accurate identification is required. This work utilises a cytochrome oxidase I partial mitochondrial gene region (COI) to distinguish the two of the main UK blowfly species -- Calliphora vicina (Robineau Desvoidy) and Calliphora vomitoria (Linnaeus) (Diptera:Calliphoridae). Seventeen interspecific differences in COI sequence were located. Use of the restriction enzyme SfcI on this gene region provides a simple method for distinguishing between C. vicina and C. vomitoria.
