中文摘要 | 據文獻報導粉斑螟蛾 (Cadra cautella (Walker) 之性費洛蒙組成分有兩種 I: 乙 酸 (Z,E)-9,12- 十四雙烯 -1- 基 酯 ((Z,E)-9,12-tetradecadien-1-yl acetate, Z9E12-14:Ac) 、 II :乙酸 (Z)-9- 十四烯 -1- 基 酯 ((Z)-9-tetradcen-1-yl acetate, Z9-14:Ac),其比例 I/II 介於 1.8/1 至 7.5/1 之間。本試驗以六角型轉盤及風洞檢 測 I/II = 100/0、0/100、1.8/1、2/1、2.2/1、3.6/1、4.9/1、7.5/1、8/1、10/1、12/1 及 15/1 等 12 種不同比例配方,對粉斑螟蛾之誘蟲活性,結果顯示以 I/II = 12/1 對粉斑螟蛾具較佳之誘引效果。比較聚氯乙烯塑膠微管及白色橡皮帽等兩種不同載體 配方對粉斑螟蛾之誘引性,以白色橡皮帽較佳,其誘蟲百分率為 61.9%,顯著高於聚 氯乙烯塑膠微管 36.9%。性費洛蒙誘餌不同劑量配方對粉斑螟蛾之誘引性,於劑量 0.1、0.5、1、2 及 4 mg 之試驗中,以 4 mg 劑量處理誘蟲百分率顯著較高 (30.3%); 其次為 1 及 2 mg 劑量處理者,誘蟲百分率分別為 23.8 及 22.2%。於劑量 1、2、 4、8 及 16 mg 之試驗時,顯示其間之誘蟲百分率無顯著差異,其誘蟲百分率介於 18.7~22.2%。性費洛蒙裝填於聚氯乙烯塑膠微管的持效性可達 4 週,白色橡皮帽的 持效性可達 16 週。綜合以上結果,粉斑螟蛾之性費洛蒙誘餌以 I/II = 12/1,1 mg 裝 填於白色橡皮帽較具誘引有效及經濟性。 |
英文摘要 | According to the reports, the sex pheromone components of the almond moth, Cadra cautella (Walker) were I: (Z,E)-9,12-tetradecadien-1-yl acetate (Z9E12-14:Ac) and II: (Z)-9-tetradcen-1-yl acetate(Z9-14:Ac). The proportions of I/II ranged between 1.8/1 to 7.5/1. In order to improve the attractiveness of the sex pheromone lure of the almond moth, the following 12 formulas: I/II = 100/0, 0/100, 1.8/1, 2/1, 2.2/1, 3.6/1, 4.9/1, 7.5/1, 8/1, 10/1, 12/1 and 15/1, were compared with turn table and with wind tunnel bioassays. The results showed that the attraction of the formulation of Z9E12-14:Ac/Z9-14:Ac = 12/1 on a white rubber septum was more attractive to the almond moth than the same formulation in a PVC microtube. The percentage of the total moth catch with the white rubber septum (61.9%), was significantly higher than that of the PVC microtube (36.9%). The attraction of the sex pheromone lures to the almond moth at different dosages was measured in percentage of total number of males trapped. For the low dosage tests, the lure dosage of 4 mg trapped the most male moths (30.3%), which was significantly higher than the lure dosage of 1 mg (23.8%) and 2 mg (22.2%). There was no difference in attraction to the almond moth in the lure dosages of 1, 2, 4, 8, and 16 mg. In the high dosage tests the percentages of the total number of males trapped ranged from 18.7-22.2%. The attraction of the lure in the PVC microtube lasted up to 4 weeks in the field, while the rubber septa lures lasted up to, 16 weeks. It was concluded that the most economical and most attractive formulation of the sex pheromone lure for the almond moth was the 1 mg dosage, I/II = 12/1 ratio, on a rubber septum. |
