| 摘 要： | 线粒体DNA具有进化速率较核DNA快,遗传过程不发生基因重组、倒位、易位等突变,并且遵守严格的母系遗传方式等特点,其广泛应用于昆虫分类和界定、系统发育关系及种群遗传变异和进化等研究。细胞色素b（cytochromeb,Cyt b）是线粒体13个蛋白质编码基因中结构和功能被研究得最为清楚的基因之一,本文对mtDNA和Cyt b基因的分子特点及Cyt b基因在昆虫研究中的应用进行简要综述。 |

| Abstract: | Mitochondrial DNA has advantages over nuclear DNA in estimating phylogenetic relationships among insect taxa because of its rapid evolution and inheritance without gene recombinations.Mitochondrial genome are widely used in insect of species identification,phylogenetic relationships and population structure within a species.Cytochromeb（Cyt b） gene is probably the best-known mitochondrial gene with respect to structure and function of its protein product.The paper brief summarized the molecular characteristics of mtDNA and Cyt b gene and Cyt b gene application in insects in order to provide basic information for the future study in insect. |
