The mitochondrial genome of the common cattle grub, Hypoderma lineatum.

The mitochondrial DNA of the cattle grub Hypoderma lineatum (de Villers) (Diptera: Oestridae) was completely sequenced. The entire molecule was 16,354 bp long and presented a heavy bias towards A + T, which accounted for 77.8% of the whole genome. Hypoderma lineatum genes were organized in the same order and orientation as in the mitochondrial genomes available for other species belonging to the Oestroidea superfamily and compared in this study [Chrysomya putoria (Wiedemann), Cochliomyia hominivorax (Coquerel), Lucilia sericata (Meigen) and Dermatobia hominis (L.)], except for the occurrence of a 102-bp non-coding region partially present in other species. The complete sequence of H. lineatum will represent a useful dataset to evaluate the evolutionary pattern of mtDNA within Oestroidea by using molecular information in diagnostic, taxonomic and evolutionary studies.
