韓國非武裝地帶隣近 6個地域의 초파리 分布相

Drosophilid Fauna of Six Regions Near the Demilitarized Zone in Korea

1. 1966年 10月부터 1968年 6月 사이에 걸쳐 韓國非武裝地帶隣近 6個地域의 초파리 分布相을 調査하였던바 7屬 34種 5022個體를 採集하였다. 2. D. auraria 와 D. angularis는 대체로 모든 地域에서 多數 採集되었으며 이밖에도 Scaptomyza屬의 초파리가 sweeping法에 의하여 풀밭에서 많이 採集되었다. 3. 東部地域에서는 7屬 27種 1552個體가 採集되었는데 이 個體數는 全體의 30.90%였다. 4. 總採集個體數의 52.93% 인 2658個體가 中部地域에서 採集되었는데 이를 整理한 結果, 6屬 29種이었다. 5. 西部地域에서는 3屬 16種 812個體가 採集되었는데 이는 全體의 16.17%였다.

Collections of the drosophilid flies were made at 6 regions near the dimilitarized znoe form October 1966 to June 1968, with particular attention to their habitats and distribution. A total of 5022 flies representing 34 species belonging to 7 genera were obtained mostly by the traps baited with fermenting apples and banana, partially by the aid of net. The data accumulated for about 21 months are summarized in this paper. Drosophila auraria and D. angularis were found to be most common species showing the most extensive distribution. In eastern part, a total of 1552 individuals(30.90%) representing 27 species, 7 genera were sampled. In central part, a total of 2658 flies (52.93%) yielded 29 species, 6 genera. In western part, a total of 812 specimens(16.17%) which belong to 16 species representing 3 genera were collected. Most specimens belonging to the genus Scaptomyza have been found on grasses.
