项目摘要

It is the final year of "the Japan-China Joint Studies on Chinese Drosophila". This project has started on 1983, and continued until 1993. many, many Japanese and Chinese scientists have been studying together in China as well as in Japan. We have collected drosophilid flies in almost all over the mainland China.Only 30 species were recorded from the mainland China, before this project had started. After our investigation, the number of known species of Drosophila has drastically increased. At present, March 1994, 415 species are known in total and the total number of species reaches 755, including unclassified specimens, which might be new species. This figure is about 2.8 times of all species found in Japan, and be the one fifth of total number of species in the world.From the fruitful results of our joint studies, new and interesting research works will develop in the fields of taxonomy, biogeography and evolutionary genetics. These results make it possible to rewrite the history of … More Drosophila evolution of the world. The numbers of known, unclassified and the total species in different province are as follows:In total 36 original papers have been published about Chinese Drosophila by Japanese and Chinese scientists, since 1985. All papers will be valuable in taxonomy and evolutionary genetics of family Drosophilide.The results of this academic year, 1993, are as follows:(1) Kitagawa and Fuyama, Tokyo Metropolitan University, collected drosophilid flies in Xinjang-weiguer Autonomous Region with Li Guochang, Entomack, and Muhtar of Xinjang univeristy. All samples collected there are now under inspection. The number of species will be realized in next summer.(2) Toda and Kimura, Hokkaido University, got the permission of free collection of flies in the Jianfeng National Forest Reserve in Hainan Island, through Prof. Peng, Guangdong Entomological Institute. They collected flies there and classified samples in Guangdong Entomological Institute. Some specimens which were difficult to classify were carried to Japan by two Chinese scientists in October, 1993. The total number of species was 161, including 104 known and 57 unidentified species. Fifty-seven unidentified species are now reserved in Hokkaido University and they are now under inspection.(3) Kitagawa and Aotsuka visited Institute of Zoology, Academia Sinica, Taiwan, in November. They carried out evolutionary genetic studies on the Drosophila immigrans species-group using the isozyme and mitochondrial DNA analyses with Professors Lin and Chang in Institute of Zoology. They are now calculating the genetic distance between populations.(4) Kimura has studied the comparative studies on body color of Drosophila elegans collected in the mainland China, Taiwan, Hongkong and Japan. The result of cross experiments showed that all populations belong to the same species and the color difference caused by a pair of alleles. Less

今年是“日中中国果蝇联合研究”的最后一年，这个项目从1983年开始，一直持续到1993年。很多很多的日本和中国科学家在中国和日本一起研究。几乎在中国大陆各地都采集了果蝇。在本项目开始之前，中国大陆仅记录了30种果蝇，经过我们的调查，目前已知的果蝇种类数量急剧增加。 1994年3月，已知共有415种，总数达到755种，其中包括未分类的标本，可能是新种，这个数字约为日本发现的所有物种的2.8倍，占总数的五分之一。从我们联合研究的丰硕成果中，将在分类学、生物地理学和进化遗传学领域开展新的、有趣的研究工作，这些结果使改写……更多的历史成为可能。世界果蝇进化史，已知的、未分类的数量和各省的总种数如下：自1985年以来，日本和中国科学家共发表了36篇关于中国果蝇的原创论文。所有论文都将具有分类学价值。 1993年本学年的研究结果如下：(1)东京都立大学北川和富山在新疆维古尔自治区与新疆大学的李国昌、恩托马克和穆塔尔目前正在检查物种数量。(2) 北海道大学户田和木村获得许可。广东省昆虫研究所彭教授在海南岛尖峰国家森林保护区免费采集苍蝇，并进行了样本分类。广东昆虫研究所。1993年10月，两名中国科学家将一些难以分类的标本带到了日本。总数为161种，其中已知104种，不明种57种，目前北海道保存有57种。 (3)北川、青冢11月访问台湾中央研究院动物研究所，进行进化遗传学研究。与动物研究所的Lin和Chang教授利用同工酶和线粒体DNA分析对果蝇种群进行研究，他们现在正在计算种群之间的遗传距离。（4）Kimura进行了果蝇体色的比较研究。采集于中国大陆、台湾、香港和日本，交叉实验结果表明，所有种群均属于同一物种，由一对等位基因引起的颜色差异较小。
