摘要: The variation in mitochondrial cytochrome oxidase 1 (mtCOI) and 16S rRNA in the 15 colour morphs of Harmonia axyridis Pallas from China was analysed. The results show that there are 170 and 233 variable sites in the gene sequences of mitochondrial DNA in the COI and 16S rRNA genes, respectively. A seven-base insert segment (CGACTAC) was found in COI-B1B and COI-Y4D, whereas no such fragment was found in the 16S rRNA. Results suggest that the genetic differences amongst most individuals are small, thus similar colour morphs do not cluster in the same branch, and these variations have no taxonomic significance.
