| 中文摘要 | 台灣蓮霧於 2005 年出口檢疫首次被查核到近似米爾頓釉小蜂物種 Anselmella cf. miltoni。 該害蟲於蓮霧花期產卵,並刺激果實胚珠形成類似種子般的蟲癭,待個體發育完成並羽化離開果實 時,使果實留下孔道,不僅影響商品價值,更被視為台灣蓮霧出口之檢疫害蟲,危及外銷收益,導 致重大經濟損失。為提供多元且發展合適的防治策略,本實驗利用固相微量萃取裝置 (Solid-phase micro-extraction, SPME) 與氣相層析質譜儀 (Gas chromatography-mass spectrometry, GCMS) 分析寄主花的揮發物組成,並從中選用可作為誘引 A. cf. miltoni 成蟲之成分,再以此成分之 化合物測試其對雌蟲的誘引效力。蓮霧三品種花的氣味分析顯示具 β-Caryophyllene 與 Cyclohexa-1,3-diene 成分,進一步測試 A. cf. miltoni 雌蟲對其合成化合物之偏好,結果顯示 βCaryophyllene 對雌蟲的吸引力顯著高於對照組 (空氣)、南洋種蓮霧花和蒲桃花;但 Cyclohexa1,3-diene 對雌蟲的吸引力僅顯著高於對照組 (空氣)。本研究以具吸引潛力之化合物單品及寄主花 的揮發物作為其對 A. cf. miltoni 雌蟲的氣味誘引初探,未來可進一步於田間實際測試其誘引力, 亦可同時搭配黏蟲板,發展田間誘引裝置,降低其對蓮霧的危害。 |
| 英文摘要 | Anselmella cf. miltoni Girault was first intercepted in Taiwan’s exported wax apples (Syzygium samarangense) in 2005. The pest induces seed-like galls by females laying eggs on the anthesis stage of the wax apple, and the stimulated ovules develop into galls. When emerging adults leave the galled fruit, they make tunnels that cause damage and affect the fruit’s value. Furthermore, the species is regarded as an exported quarantine pest, lowering the export profits and causing significant economic losses. To develop multiple and appropriate strategies for controlling the pest, we use the Solid-phase micro-extraction (SPME) and Gas chromatography-mass spectrophotometer (GC-MS) to analyze the composition of the host flower volatiles and to determine attracted components to Anselmella cf. miltoni, and then potential attracting flower volatiles, β-Caryophyllene and Cyclohexa1,3-diene, were chosen for preliminary tests of attraction effectiveness on the females using the identical synthetic compounds. The attractiveness of β-Caryophyllene to females was significantly higher than that of air treatment (control) and flower volatiles of rose apple and wax apple (Pink variety). However, the attractiveness of Cyclohexa-1,3-diene to females was only significantly higher than that of the air treatment (control). In the future, the tests on the attractiveness of these chemical compounds to the female Anselmella cf. miltoni could be conducted in the field, which may be used with a sticky board to develop a dual-attracting trap and reduce injury in the wax apple. |
