Abstract: The genomic DNAs of three species of Aedes (Aedes albopictus、 Ae.aegypti 、 Ae.togoi）were amplified by RAPD-PCR technique with three primers (P_z、 P_w、 P_L).Different maps were obtained.Most of the amplified fragments are unique to one species, and some of fragments are common forthree species.These results indicate that the RAPD-PCR technique may be useful in studies of mosquitomolecular taxonomy.for its simplification、rapidness、and exactness.

摘要： 目的：探讨3种伊蚊细胞系基因组多态性DNA。方法：应用3个引物，通过随机引物扩增多态性DNA聚合酶链反应技术（RAPD-PCR），对东乡伊蚊、埃及伊蚊和白纹伊蚊的细胞系基因组DNA进行扩增。结果：分别扩增出不同数量和分子大小的多态DNA图谱；3种伊蚊细胞的基因组DNA扩增产物除了有部分相同分子大小的DNA条带外，还有各自独特的DNA条带。结论：此方法简便、快速、精确，可用于蚊虫的分子分类研究。
