中文摘要 費洛蒙係指同物種間傳遞訊息的化學物質,而性費洛蒙的作用則是吸引異性交配,藉以繁殖下一代。因此以人工合成方式研發昆蟲性費洛蒙,大量生產藉以誘捕害蟲,降低害蟲的交配繁殖率,可以達到蟲害防治的目的。 在台灣,玉米的主要害蟲為亞洲玉米螟(Ostrinia furnacalis),但在文獻中亞洲玉米螟性費洛蒙的配方仍有爭議。本研究以實驗室合成之亞洲玉米螟性費洛蒙(E12-14:Ac / Z12-14:Ac),藉由田口方法做實驗設計與統計分析,希望能研究出其最佳劑量、配方及誘捕條件。 經實驗趨勢分析統計,及確認實驗證明,其最適化條件如下: 1. 劑量2.5mg 2. E12-14:Ac / Z12-14:Ac比例1:3 3. 費洛蒙載具微管長度 6cm至7cm 4. 翼形黏蟲板頂蓋與黏板間距 5cm 期待未來經由推廣,將此研究結果大量使用於玉米蟲害防治,減 少農藥的使用,使綠色農業再往前邁出一步。
Abstract Pheromones are the chemical substances with which the same species exchange messages and the role of sex pheromones is to attract the opposite sex to breed. Synthesized insect sex pheromones are used to trap pests and reduce pest breeding rate so as to control pest damages. In Taiwan, Ostrinia furnacalis is the major corn pest. In the literature the formulation of Ostrinia furnacalis sex pheromone is still unresolved. This study aims to investigate the optimum dose, formulation, and trap conditions of synthesized Ostrinia furnacalis sex pheromone by adapting Taguchi Method. After applying trend analysis and confirmation experiment, the study has reached the following optimum conditions: 1. The dose is 2.5mg. 2. The proportion of E12-14:Ac / Z12-14:Ac is 1:3. 3. The length of pheromone microtubule is between 6 cm and 7 cm. 4. The distance between the wing-shaped trap cover and the sticky board is 5 cm. It is hoped that based on the research results the synthesized sex pheromones can be widely used in corn pest control and thus the environmentally friendly agriculture can be enhanced.
