摘要

本研究於室內網籠測試44種植物揮發性成分對東方果實蠅雌蟲之誘引效果，結果顯示44種供試成分中有15種化合物對東方果實蠅雌蟲有明顯的誘引效果，其中丁酸丁酯、乙酸異戊酯及己酸乙酯對雌蟲誘捕率分別為53.5、69.0及60.0%，效果最好。此15種室內試驗篩選出之有效成分續於戶外進行網籠試驗，結果丁酸丁酯、乙酸異戊酯、己酸乙酯及乙酸正丁酯對雌蟲之誘捕率分別為18.2、15.1、9.5 及18.2%，與對照組間有顯著差異。此4種植物揮發性成分值得進一步探討其可能的應用性。

Forty-four plant volatiles were tested for their attractiveness to females of the oriental fruit fly in laboratory, and 15 out of 44 volatiles significantly attracted female flies in laboratory cage tests. Butyl butyrate, isoamyl acetate, and ethyl hexanoate were the best three in these 15 volatiles; with female trapping rates of 53.5, 69.0, and 60.0%, respectively. In the following field cage tests for these 15 volatiles, butyl butyrate, isoamyl acetate, n-butyl acetate, and ethyl hexanoate showed significant attractiveness to female flies compared to the controls. The female trapping rates were 18.2, 15.1, 9.5, and 18.2%, respectively. These 4 plant volatiles deserve investigation for possible applications.
