殺蟲劑 散布에 따른 畓眞正蜘蛛目 集團의 變動에 關하여 = Studies on The Change of Paddy rice ARAEINA Populations by The Diffusion of Insecicide

다국어 초록 (Multilingual Abstract)

1. 慶尙北道 軍威郡 山城面 三山洞所在 沓 6個地區에서 1964年 7月부터 10月에 걸쳐 殺蟲劑 散布에 따른 眞正蜘蛛目의 個體數 變動에 關한 調査를 하였다.
2. 殺蟲劑 散布에 따라 眞正蜘蛛目의 個體數가 顯著하게 減少하였으며, 無散布區에 比해서 減少한 期間은 60日間 以上 繼續되었다.
3. 各種 殺蟲劑 散布에 따른 眞正蜘蛛目의 減少는 BHC가 5∼24%로서 가장 甚한 影響을 주며, EPN가 43∼60%로서 다음이고, E ·P는 45∼86%, M ·P는 47∼88%였으며, Dipterex는 60∼98%로서 가장 影響이 弱하였다.
4. E ·P ·M ·P 散布의 境遇는 個體數回復이 EPN Dipterex BHC에 比해 15日 程度 빨랐다.
5. BHC 및 Dipterex 以外의 散布 境遇는 個體數 回復後 無防除의 境遇보다 大體로 增加하는 傾向을 보여 주었다.

1. A field investigation on the change of ARAEINA populations after the diffusion of insecticide was made in 6 rice-paddies located at Samsan-Dong Sansung-Myun, Koonwi-Koon, Kyungsang-Pookdo from July, 1964 to Oct., 1964.
2. The diffusion of insecticide decreased the ARAEINA populations remarkably, and the decreasing period of spiders stretched 60 days compared with the areas with no insecticide diffusion.
3. The decreasing of ARAEINA after the diffusion of different insecticide ranged as follows: BHC (5∼24%); EPN (43∼60%); E ·P (45∼86%); M ·P (47∼88%); Dipterex (60∼98%);
4. In the case of insectieside E ·P and M ·P diffusion, the revival of the individual number was about 15 days earlier than in the case EPN, BHC and Diperex.
5. Except in BHC and Dipterex diffusion, after the revival of individual number the multiplication of individual number increased than in the areas with no insecticide diffusion.
