随机扩增的多态DNA(RAPD)是新近发展的一种聚合酶链反应(PCR)方法。用单个10bp随机序列引物作PCR,可以产生一组扩增片段。有些随机扩增的多态DNA片段,具有种或种下鉴别特征。本研究用RAPD区分盾板伊蚊Ae.scutellaris组的近缘蚊种及其同种群体,并介绍了资料的统计分析方法。盾板伊蚊组可分为两个亚组。实验用蚊种包括盾板伊蚊亚组的凯瑟伊蚊(Ae.katha-rinensis)、波利尼西亚伊蚊(Ae.polynesiensis)和里弗伊蚊(Ae.riversi);白纹伊蚊亚组的 Random amplified polymorphic DNA (RAPD) is a newly developed polymerase chain reaction (PCR) method. Using a single 10bp random sequence primer as a PCR, a set of amplified fragments can be generated. Some random amplified polymorphic DNA fragments, with species or species identification features. In this study, RAPD was used to distinguish the closely related mosquitoes and their populations from the Ae.scutellaris group. The statistical analysis method was also introduced. Shield Aedes mosquito group can be divided into two subgroups. The mosquito species used included Ae. Katha-rinensis, Ae. Polynesiensis, and Ae.riversi, a subgroup of Aedes albopictus
