Abstract: Objective:To study intra-and interspecific molecular variation and phylogeny of four members of the minimus group of Anopheles in Yunnan,which were An.aconitus,An.jeypoirensis,An.minimus species A and An.minimus species C.Method:DNA sequence divergence between these species at mitochondrial locus(cytochrome oxidaseⅠ) is reported.Results:The test confirms the presence of two cryptic An.minmus species A and C,and the relationship between the molecular variation and phylogeny of member of the An.minimus group.DNA sequence diverges between these species at mtDNA,the relationship was very close with An.minimus A and C,An.aconitus near relations was long-term distance,but the An.jeyporiensis was greater distance on divergence.Conclusion:The environment of An.minimus has an effect on genetic variations of mtDNA,but the difference geographic population of An.minimus was not much changing at genetic distance.
摘要: 目的:研究微小按蚊与种群之间(乌头按蚊、吉甫按蚊、微小按蚊AC型)线粒体DNA的分子变异及系统发育关系。方法:PCR扩增和mtDNA测序。结果:在云南发现两个微小按蚊隐形种,即微小按蚊AC型;证实了微小按蚊种团之间遗传差异,微小按蚊AC分歧时间稍晚于乌头按蚊,吉甫按蚊分歧时间远早于前2种。结论:地理环境对mtDNA遗传差异有一定影响,但不同地理的群体之间微小按蚊的遗传距离没有明显变化
