摘要基于33个可能的酶基因座的遗传变异，研究了果蝇亚群8种果蝇的系统发育关系。Nei‘s遗传距离的范围为0-28~1-74。Sechellia似乎更接近于拟南星，而不是毛刺盘藻，前者是亲缘关系最近的。Orena与D.erecta的亲缘关系较远(DS=1)。遗传分化支持黑腹蛇亚群内三个主要谱系的存在，Yakuba-teissieri对似乎更接近黑腹蛇血统，而不是直立体-Orena血统。从等位酶数据中推断了物种分化的时间，并讨论了它们与其他估计的一致性。有
Summary The phylogenetic relationships of the eight species of the Drosophila melanogaster subgroup are examined on the basis of genetic variation at 33 putative enzyme loci. Values of Nei's genetic distance (ds) range from 0-28 to 1-74. D. sechellia appears closer to D. simulans than to D. mauritiana, the two former being the most closely related. D. orena is quite distantly related to D. erecta (ds = 1). Genetic differentiation supports the existence of three main lineages within the melanogaster subgroup and the yakuba-teissieri pair appears to be closer to the melanogaster lineage than to the erecta-orena one. Inferences of the times of species divergence from allozyme data are made and their agreement to other estimates is discussed. have
