| 摘 要： | 本文报道１９９１年秋果蝇（Ｄ．ａｌｂｏｍｉｃａｎｓ）突然迁入上海的事实。我们用９种限制性核酸内切酶对上海、嘉定、青浦和南汇４个群体的２９个单雌系的线粒体ＤＮＡ进行了酶切片段长度多态性研究，发现每个单雌系各有其特征的酶切图谱。在与广东、昆明、台湾珊瑚潭、日本洲本及马来西亚吉隆坡群体比较后，我们认为上海及邻近地区突然发现的Ｄ．ａｌｂｏｍｉｃａｎｓ来自中国大陆南部的多个群体。这一结论支持该种目前正处于向北迁移的分化阶段的观点。我们还对线粒体ＤＮＡ的种内多态性进行了讨论

| Abstract: | We report the fact that D. albomicans invaded into Shanghai suddenly in the autumn of 1991.Using 9 restriction enzymes,we analyse the RFLPs of mitochondrial DNA of 29 isofemale lines belonging to 4 populations of Shanghai,Jiading,Qinpu and Nanhui.We find that all 29 haplotypes are different from each other. Comparing with the populations of Canton,Kunming,Sanhutanaaa(Taiwan),Sumoto(Japan),and Kuala Lumper(Malaysia),we come to the conclusion that D. albomicans caught in Shanghai and areas nearby is from a few of places in the south of China-mainland.This conclusion agrees with the viewpoirlt that this species is on the speciation stage of migration towards north.We also discuss the mtDNA polymorphism within the species. |
