| Popis: | A new outbreak pest, Athetis lepigone (Moschler) (Lepidoptera: Noctuidae), has caused severe economic loss in maize crops in China. In order to conduct population genetics study with a more polymorphic and scientific mitochondrial marker, we sequenced the complete mitochondrial genomes of 13 different A. lepigone individuals. Intraspecific comparison of all PCGs showed that the NADH dehydrogenase and cytochrome b genes had the highest nucleotide diversity. We also found evidence of episodic positive selection on two amino acids, which are encoded by NADH dehydrogenase genes (ND3 and ND4L), against a background of widespread neutral selection of all other mitochondrial PCGs. The genetic divergence observed in this study indicated that the cytochrome b gene (CYTB) is better than COI at recovering population structure. The preliminary population genetic analysis illustrated strong gene flow among A. lepigone populations in China. Our study provides basic information for further research on population genetics of A. lepigone. |
