项目摘要

The Drosophila virilis section was studied from an evolutionary point of vies of adaptive radiation and biodiversity in green belts of East Asia. Most species of the virilis section living in the temperate region repeated generation alternation several times per year, and the females did not develop their ovaries from mid September and entered reproductive diapause for hibernation. Any species belonging to the large quadrisetata species group has not been known for seasonal changes of natural populations, and it is first known that Drosophila quadrisetata spends two generations per year. The virilis section flies used cliff-shelters covered by roots of trees or ferns along stream as hibernation sites. Drosophilaokadai of the robusta group characteristically spent a single generation per year.Several species were maintained under various photoperiodic conditions from the egg stage and studied for the development of ovaries. Reproductive diapause was induced under short daylength in Dros … More ophila okadai, a uni-voltine species, and this has showed that diapause of Drosophila okadai is facultative and a single generation per year is due to the limited period suitable for the life of Drosophila okadai.On the other hand, ovarian development proceeded without any delay even under short photoperiodic regimes in Drosophila daruma, a tropic or subtropical member of the polychaeta species groupLocal populations of Drosophila tsigana, a member of the melanica species group, showed remarkable morphological variations for the band patters on the abdominal tergites. The warm temperate form collected from Tokyo and Kyoto possessed entirely black tergites of males but the cool temperate one from central Hokkaido did black caudal bands interrupted largely at middle on tergites II to IV. Any discriminative character on the male genitalia was not been detected between these two forms.Reproductive isolation was studied by no-choice method, and incomplete isolation was detected between the two forms of Drosophila tsigana. A mitochondrial gene of COI was analyzed, and the gene sequences were compared among local populations of Drosophila tsigana. The molecular phylogenic tree showed that the warm temperate form of Japanese Drosophila tsigana was situated near to Chinese Drosophila tsigana collected from Guizhou, rather than the cool temperate form of Japanese Drosophila tsigana.

从适应辐射和东亚绿色带生物多样性的角度对果蝇组进行了研究。生活在温带地区的雄性组大多数种每年重复几次世代交替，雌性从9月中旬开始不发育卵巢，进入生殖滞育冬眠。任何属于大四毛种组的物种都没有自然种群的季节变化，并且首次知道四毛果蝇每年花费两代。雄蝇科的蝇类以沿着的树根或蕨类植物覆盖的悬崖掩蔽处作为冬眠场所。果蝇robusta组的特点是每年花一个世代。几个物种保持在不同的光周期条件下从卵期和卵巢的发育进行了研究。短日照诱导了Dros的生殖滞育 ...更多信息 Ophila okadai的滞育是兼性的，一年只发生一代是由于Ophila okadai的生活期有限所致。另一方面，Drosophila daruma的卵巢发育即使在短光周期下也没有任何延迟。的成员黑属种组，显示出显着的形态变化的带状图案的腹部背板。从东京和京都采集的暖温带类型具有完全黑色的雄性背片，但从北海道中部采集的冷温带类型在背片II至IV的中部有黑色的尾带中断。用无选择法研究了两种果蝇的生殖隔离，发现两种果蝇的生殖隔离是不完全的。对果蝇COI基因进行了序列分析，并对不同地方种群的COI基因序列进行了比较。分子进化树显示，日本果蝇的暖温型与中国果蝇的贵州亚种相近，而日本果蝇的冷温型与中国果蝇的贵州亚种相近。少
