中文摘要 | 本試驗以六角型轉盤裝置與風洞兩種室內生物檢定方法及田間誘蟲試驗,檢定不同性費洛蒙配方 對花姬捲葉蛾雄蟲之活性。結果顯示,雄蛾在田間對性費洛蒙反應時段出現於見光後2-4小時之間, 於見光後3小時達高峰,誘捕率為65%;風洞試驗中則出現於見光後2-5小時之間,雄蛾反應率介於 48-49.6%。以六角型轉盤檢定Z7DDA、Z8DDA及Z9DDA 對雄蛾的活性,結果與田間誘蟲試驗結果 一致,均僅Z8DDA對雄蛾具有誘蟲活性。Z8DDA不同劑量對雄蛾之誘引力,在六角型轉盤檢定結 果及田間誘蟲試驗者一致,均以1 mg之誘引效果最佳;風洞試驗則以10 μg以下劑量才表現誘引效 果。Z8DDA/E8DDA不同混合比例對花姬捲葉蛾雄蛾之誘引效果,風洞以10 μg,六角型轉盤試驗 以1 mg,與田間誘蟲試驗以1 mg誘餌表現一致的結果,均以100/0或99.5/0.5之配方有較佳的誘蟲效 果,誘餌中含E8DDA 0.5%以上即影響誘蟲效果。Z8DDA/Z8DDOL不同混合比例對雄蛾之誘引性, 田間試驗結果顯示劑量為1 mg時,Z8DDA/Z8DDOL =100/100的配方最具誘蟲效果;風洞及六角型 轉盤試驗結果以100/0及100/5的配方誘引效果較佳。 |
英文摘要 | The attractiveness of different fomulation lures to the carambolla fruit borer, Eucosma notanthes Meyrick was conducted with two bioassay methods, i.e., turntable and wind tunnel, in laboratory. The results were also compared with those done in field test. The attractive period of sex pheromone lures to males was 2 to 4 hr after light on, and peak attraction was 3 hr after light on in the field. The attractive period was found 2-5 hr after light on, and reactive rate was between 48 to 49.6% by wind tunnel test. The results of attractiveness of Z7DDA, Z8DDA, and Z9DDA to males were similar to those observed in the field. Only lures of Z8DDa exhibited bioactivity to males. The results of attractiveness of different dosages of Z8DDA to males in turntable test were similar to those of field test. The best attractiveness was obtained using 1 mg by turntable and field test, while lures below 10 ug exhibited attraction to males by wind tunnel. The results of attractiveness of different blend ratios of Z8DDA and E8DDA to males were same by using turntable (1 mg), windtunnel (10 ug), and field test (1 mg). The blend ratios of Z8DDA and E8DDA at 100/0 or 99.5/0.5 showed more attractive to males then others. The lures containing more than 0.5% E8DDA lowered their attractiveness. Attractiveness of different blend ratios of Z8DDa and Z8DDOL were different by turntable, wind tunnel, and field test. Blend ratios testing with field test, turntable, and wind tunnel were best at Z8DDA/Z8DDOL=100/100, 100/0, and 100/5, respectively. |
