瘤野螟(Cnaphalocrocis medinalis Guene, Rice leaf folder)是二期稻作生育期間重要的害蟲。本試驗目的在評估日本(Z11-18:Ald (55 μg)、Z13-18:Ald (500 μg)、 Z11-18:OH (120 μg)、Z13-18:OH (180 μg))、菲律賓(Z11-16:Ac (500 μg)、Z13-18:Ac (10 μg))及印度(Z11-16:Ac (50 μg)、Z13-18:Ac (500 μg))等三種瘤野螟合成性費洛蒙配方對瘤野螟成蛾之誘引能力。結果顯示日本配方誘餌對臺灣的水稻瘤野螟具有誘蟲活性,菲律賓及印度配方誘餌僅捕獲極少量成蛾。因此,性費洛蒙誘蟲組的最佳配置條件及後續試驗均以日本配方製劑為供試誘餌。性費洛蒙載體比較以塑膠微管較橡皮帽有較佳的誘引效果。性費洛蒙誘餌有效誘引期間可達1.5個月以上。誘蟲盒高度試驗顯示,距離水稻植株上方0 m較0.2 m及0.4 m誘集到較多的瘤野螟成蛾。此外,誘蟲盒在田間的配置亦會影響到瘤野螟誘引效果。性費洛蒙誘集蟲數與田間掃網捕獲成蛾數量及誘蟲燈誘集數量,在瘤野螟族群變化上有相近的趨勢。顯示合成性費洛蒙應可作為瘤野螟田間族群發生監測之用。
Rice leaf folder, Cnaphalocrocis medinalis Guene, is a seriously insect pest in the cultivated periods of second-cropping rice. Field bioassays using three types of synthetic sex pheromone blends (Japanese blend: Z11-18:Ald (55 μg), Z13-18:Ald (500 μg), Z11-18:OH (120 μg) and Z13-18:OH (180 μg), Indian blend: Z11-16:Ac (50 μg) and Z13-18:Ac (500 μg) and Philippine blend: Z11-16:Ac (500 μg) and Z13-18:Ac (10 μg) based on geographic variations in sex pheromones) for the rice leaffolder moth, Cnaphalocrocis medinalis Guenée (Lepidoptera: Crambidae), were performed at different sites of Changhua and Taichung County in Taiwan. Results showed that only the Japanese blend attracted significant numbers of male C. medinalis, while the Indian and the Philippine blends only showed little attractiveness to the males. In addition, no C. medinalis adult was captured in the un-baited trap. Therefore, the Japanese blend was used for field evaluation to get the suitable condition for application. Pheromone lures stuffed in polyethylene microtube was better in attractiveness than rubber septum, and its effectiveness could last one month. More C. medinalis moths were caught in traps at heights of 0 m than at 0.2 and 0.4 m above rice plants level. The placement of traps were also affected the attractiveness of C. medinalis moths, and had significant different. Preliminary comparison of efficiency and the fluctuation pattern of C. medinalis moths catch between the pheromone traps and sweeping nets, they had similar trend in the field. The synthetic sex pheromone blend ocould be used as the tool for monitoring C. medinalis moths in Taiwan.
