title: The complete mitochondrial genome of the beet armyworm Spodoptera exigua (Hübner) (Lepodiptera: Noctuidae).
abstract: The complete mitochondrial genome of the beet armyworm Spodoptera exigua (Hübner) (Lepodiptera: Noctuidae) was determined (GenBank accession number JX316220). The genome is 15,365 bp long with 37 typical animal mitochondrial genes and an A+T-rich region. As in other sequenced mitochondrial genomes of Lepidoptera, trnM was rearranged to the upstream of trnI-trnQ-trnM cluster compared with the pupative ancestral arrangement of insects. All protein-coding genes start with ATN start codon except for the gene cox1, which uses CGA as in other lepidopteran species. Eight protein-coding genes stop with termination codon TAA. Five protein-coding genes use incomplete stop codons TA or T. The A+T-rich region is located between rrnS and trnM with a length of 331 bp. This is the third completely sequenced mitochondrial genome from the family Noctuidae of Lepidoptera.
