Mitochondrial DNA restriction site map of Cochliomyia macellaria (Diptera: Calliphoridae)

The mitochondrial DNA of the secondary screwworm, Cochliomyia macellaria (F), was cleaved with 15 restriction endonucleases to produce 54 restriction fragments. Forty-three restriction sites recognized by 12 enzymes were assigned positions on a restriction site map. Both the restriction fragments and the restriction site map were compared with published data from the screwworm, Cochliomyia hominivorax (Coquerel). The restriction site maps were aligned using a combination of highly conserved restriction sites. Estimated nucleotide divergence between the 2 species based on the fragments was 0.052. The divergence based on the restriction site map was 0.093. The data provide a baseline for future population or phylogenetic investigations.
