中文摘要 | 本試驗利用載體 (TPE:DOP:Pheromone=97.9:1.6:0.5) 及合成性費洛蒙 ((Z)-9-tetradecenyl acetate:(Z)-11-tetradecenyl acetate:(E)-11-tetradecenyl acetate:10-methyldodecyl acetate=63:31: 4:2,每條性費洛蒙交配干擾劑含合成性費洛蒙之總重量為85mg),來探討高密度 (每隔5 公尺) 及 低密度 (10 公尺) 設置,對二茶區 (桃園楊梅及新竹關西) 茶姬捲葉蛾及茶捲葉蛾之誘引抑制效果 進行田間干擾試驗。結果顯示性費洛蒙交配干擾劑在兩茶園皆能有效抑制茶姬捲葉蛾及茶捲葉蛾; 由迴歸方程式顯示,茶姬捲葉蛾的族群數於600 隻以下時,高密度設置的誘引抑制效果優於較低密 度,但當族群量高於600 隻後誘引抑制效果則漸達到飽和,兩密度間差則不顯著;茶捲葉蛾的誘引 抑制能力同樣是在高密度的設置效果較佳。 |
英文摘要 | This study aims to understand the inhibition effects of smaller tea tortrix and tea tortrix with the different density (5m and 10m interval) of the carrier (TPE: DOP: Pheromone=97.9: 1.6: 0.5) and synthetic sex pheromone ((Z)-9-tetradecenyl acetate: (Z)-11-tetradecenyl acetate: (E)-11-tetradecenyl acetate: 10-methyldodecyl acetate=63: 31: 4: 2. Each mating disturbance pheromones is prepared with the total content of all pheromones to be 85 mg) placement in the fields (Taoyuan Yangmei and Hsingchu Guanxi). The results showed that the mating disturbance pheromones both effectively inhibited the growth of smaller tea tortrix and tea tortrix. However, the regression equation indicated that the inhibitive effect of high density placement of mating disturbance pheromones was better than that of the low density placement when there were less than 600 smaller tea tortrixs in the field. The difference of inhibitive effect between high and low density placement would become insignificant with more than 600 tea tortrixs. In addition, the high density placement of mating disturbance pheromones performed better on the inhibition of tea tortrix, but both the high and low density placement could effectively control tortrix number. |
