The complete sequence of the mitochondrial genome (mitogenome) of the rice stem borer Chilo suppressalis (Walker) (Lepidoptera: Crambidae) was determined to be 15,465 bp. It contains 13 protein-coding genes (PCGs), 22 tRNA genes, the large and small rRNA genes, and an A+T-rich region. The nucleotide composition of the mitogenome of C. suppressalis is highly A+T biased, accounting for 79.70% in whole mitogenome, 77.74% in PCGs, 84.70% in tRNAs, 81.20% in rRNAs and 94.19% in A+T-rich region, respectively. The PCGs have typical ATN start codons, except for cox1, which contains the unusual CGA. The C. suppressalis A+T-rich region contains a conserved structure combining the motif ATAGA and a 19-bp poly-T stretch, but absence of the 9-bp poly-A element upstream trnM.
测定了二化螟（Chilo suppressalis (Walker)，鳞翅目：草螟科）线粒体基因组（线粒体基因组）的完整序列，为15465 bp。它包含13个蛋白质编码基因（PCG）、22个tRNA基因、大、小rRNA基因以及一个富含A+T的区域。二化螟线粒体基因组的核苷酸组成高度偏向A+T，在整个线粒体基因组中占79.70%，在PCG中占77.74%，在tRNA中占84.70%，在rRNA中占81.20%，在富含A+T的区域中占94.19%。除cox1含有不寻常的CGA外，PCG具有典型的ATN起始密码子。二化螟富含A+T的区域包含一个结合基序ATAGA和一个19 bp多聚T序列的保守结构，但在trnM上游缺少9 bp多聚A元件。
