小白紋毒蛾（Orgyia postica Walker）之性費洛蒙配方與不同型式誘蟲器之誘捕效果研究

"Formulations of Sex Pheromone Lure and Trap Types of the SmallTussock Moth, Orgyia postica (Walker) (Lepidoptera: Lymantridae)"

"小白紋毒蛾（Orgyia postica Walker）屬鱗翅目、毒蛾科（Lepidoptera: Lymantridae），據文獻報導其兩種性費洛蒙組成分為I：反11S,12S-環氧-(Z)-6,（Z)-9-二十一碳二烯（trans-11S,12S-epoxy-Z6,Z9-heneicosadiene,posticlure）及II：(Z)-6-二十一烯-11-酮（Z6-heneicosen-11-one, Z6-21-11Kt）。其中I的旋光異構物（trans-11R,12R-epoxy-Z6,Z9-heneicosadiene, (-)posticlure）不會影響誘蟲效果。為研發田間有效之小白紋毒蛾性費洛蒙誘餌及誘蟲器，分別探討性費洛蒙成分不同比例、不同劑量、載體、抗氧化劑及不同型式誘蟲器對誘捕小白紋毒蛾效果之影響，以開發小白紋毒蛾之性費洛蒙應用資材。結果以含有抗氧化劑之(±)posticlure / Z6-21-11Kt =4/1，以500μg裝載於塑膠微管中為經濟有效配方，在田間可持效2個月。而化合物III：反11,12-環氧-(Z)-6,(Z)-9-二十二碳二烯（trans-11,12-epoxy-Z6,Z9-tricosadiene）的結構與I類似，其碳鏈比成分I多兩個碳，對小白紋毒蛾不具誘蟲效果。不同型式誘蟲器對小白紋毒蛾之誘捕效果，以翼型黏膠式誘蟲器對小白紋毒蛾之誘捕效率優於二層上衝式寶特瓶誘蟲器、中改式誘蟲器、一層上衝式寶特瓶誘蟲器。"

"According to previous reports on the small tussock moth (STM), Orgyia postica (Walker) (Lepidoptera: Lymantridae), there are two sex pheromone components, trans-11S,12S-epoxy-Z6,Z9-heneicosadiene (posticlure), and Z6-heneicosen-11-one (Z6-21-11Kt). The isomer of the former component (I) does not effective the attractiveness lure. In order to develop sex pheromone lure and trap for field application, lures with different blends, dosages, carriers, anti-oxidant, as well as various types of trap were tested in this research. The results showed that the most economic and effective lure of STM is (±)posticlure / Z6-21-11Kt =4/1 that contained BHT and loaded 500 μg in a microtube; and its field efficacy can last 2 months. Based on the comparison of trap efficiency on different trap type, the trap efficiency of wing sticky trap on STM was better than Up-2 layer PET bottle trap, TDAR trap, and Up-1 layer PET bottle trap."
