中文摘要 | 乙酸(Z)-8-十二烯-1-基酯 ((Z)-8-dodecen-1-yl acetate, Z8-12:Ac) 是花姬捲葉蛾 (Cydia notanthes Meyrick) 及粗腳姬捲葉蛾 (Cryptophlebia ombrodelta (Lower)) 之主要性費洛蒙成分。合成的Z8-12:Ac含0.5%乙酸(E)-8-十二烯-1-基酯 ((E)-8-dodecen-1-yl acetate﹐E8-12:Ac) 顯著降低其對花姬捲葉蛾之誘蟲活性;純度96%之Z8-12:Ac為粗腳姬捲葉蛾之適當誘蟲配方。本試驗分別添加乙酸1-十二酯 (1-dodecyl acetate﹐1-12:Ac)、乙酸1-十六酯 (1-hexadecyl acetate﹐1-16:Ac)、乙酸1-十八酯 (1-octadecyl acetate﹐1-18:Ac)、(Z)- 8-十二烯-1-醇 ((Z)-8-dodecen-1-ol﹐Z8-12:OH)及(E)-8-十二烯-1-醇((E)-8-dodecen-1-ol﹐E8-12:OH)等五種化合物於Z8-12:Ac/E8-12:Ac= 96/4中,於台南及員林地區楊桃果園進行田間誘蟲試驗,測試其對花姬捲葉蛾及粗腳姬捲葉蛾誘蟲活性之影響。結果顯示1-12:Ac、1-16:Ac、1-18:Ac及E8-12:OH等添加物添加於E8-12:Ac/Z8-12:Ac = 96/4對花姬捲葉蛾的誘蟲效果無影響,添加Z8-12:OH者具提升誘蟲效果。配方Z8-12:Ac/E8-12:Ac/ Z8-12:OH = 96/4/30的3次試驗對花姬捲葉蛾之誘蟲百分率均顯著較其他配方者為高,分別為81.2、69.6、80.5 %。添加1-12:Ac、1-16:Ac、1-18:Ac之配方,對粗腳姬捲葉蛾的誘蟲效果無影響;添加E8-12:OH或Z8-12:OH者則可顯著提高誘餌對粗腳姬捲葉蛾的誘蟲效果。配方Z8-12:Ac/E8-12:Ac/E8-12:OH=96/4/10對粗腳姬捲葉蛾之誘蟲百分率,顯著高於配方Z8-12:Ac/E8-12:Ac=96/4者。配方Z8-12:Ac/E8-12:Ac/Z8-12:OH = 96/4/30對粗腳姬捲葉蛾之誘蟲效果顯著高於其他配方,誘蟲百分率分別為97.9、60.7、61.9 %。因此,純度96%的Z8-12:Ac可藉以添加Z8-12:OH改進性費洛蒙誘餌對花姬捲葉蛾之誘蟲活性;添加Z8-12:OH及E8-12:OH成分增強純度96%的Z8-12:Ac對粗腳姬捲葉蛾之誘蟲效果。 |
英文摘要 | (Z)-8-dodecen-1-y1 acetate (Z8-12:Ac) is the main component of sex pheromones of Cydia notanthes Meyrick and Cryptophlebia ombrodelta (Lower). The isomer of Z8-12:Ac, (E)-8-dodecen-1-y1 acetate (E8-12:Ac), may inhibit the attraction of Z8-12:Ac to C. notanthes. The component Z8-12:Ac with purity 96% was suitable for trapping C. ombrodelta. In this experiment, five additives of 1-dodecyl acetate (1-12:Ac), 1-hexadecyl acetate (1-16:Ac), 1-octadecyl acetate (1-18:Ac), (Z)-8-dodecen-1-ol (Z8-12:OH), and (E)-8-dodecen-1-ol (E8-12:OH) were added to the base of Z8-12:Ac/ E8-12:Ac = 96/4 and used as attractants for C. notanthes and C. ombrodelta in the carambola orchards in Nanshi Township, Tainan County and Yuanlin Township, Changhua County, Taiwan. The results showed that the additives of 1-12:Ac, 1-16:Ac, 1-18:Ac and E8-12:OH did not influence the attraction of the mixture of Z8-12:Ac/E8-12:Ac=96/4 to C. notanthes. However, Z8-12:OH did enhance the attraction. Percentages of total C. notanthes males trapped with the formula Z8-12:Ac/E8-12:Ac/ Z8-12:OH = 96/4/30 at 3 experiments were 81.2, 69.6 and 69.6%, respectively. For C. ombrodelta, additives of 1-12:Ac, 1-16:Ac, and 1-18:Ac did not influence the attractiveness of the mixture of Z8-12:Ac/E8-12:Ac=96/4. Additives, E8-12:OH and Z8-12:OH, increased the attractiveness of Z8-12:Ac/E8-12:Ac=96/4 to C. ombrodelta significantly. The percentage of total males captured in treatment of Z8-12:Ac/E8-12:Ac/Z8-12:OH = 96/4/30 was higher than that of Z8-12:Ac/E8-12:Ac =96/4. The percentage of total C. ombrodelta males trapped with the formula Z8-12:Ac/E8-12:Ac/Z8-12:OH = 96/4/30 was higher than those trapped with other formula. Component Z8-12:Ac with purity 96% may improve its attractiveness to C. notanthes by adding Z8-12:OH to its sex pheromone formula. Addition of Z8-12:OH and E8-12:OH to Z8-12:Ac with purity 96% may increase its attractive effect on C. ombrodelta. |
