中文摘要 | 本試驗乃針對由中央研究院所提供之三種小菜蛾性費洛蒙誘劑,及省 農藥所所提供之九種不同混合比例誘劑,在田間比較其誘引小菜蛾雄蛾之效力。 三種配方中,主成分Z-11-16:AC+Z-11-16:ALD(1:1)可誘得雄蛾,添加Z-11-16: OH(1:1:0.02)可增加12%之誘引效果,唯較有效之誘引期間僅9天左右,但添 加Z-11-16:ALD配成9:1、8:2、7:3、6:4、1:1、4:6、3:7、2:8、1: 9等9種不同比例配方,不論添加Z-11-16:OH與否,對小菜蛾雄蛾之誘引效果 均不如一隻處女雌蛾之效力,其原因可能與主成分之純度有關。 |
英文摘要 | This experiment was carried out to measure and compare the trapping efficacy in the field for diamondback moth of a number of sex pheromone formulations. The three formulations provided by Academia Sinica had Z-11-16: AC+Z-11-16:ALD (1:1) as major components, which alone could attract female moth. Including Z-11-16:OH (final ratio of the three components 1:1:0.02) increased the trapping efficacy by 12%, yet the formulation remained effective for only 9 days. A reduction of trapping efficacy resulted when Z-9-14:AC (final ratio of the three components 1:1:0.01) was added to the formulatio. The nine formulations provided by Taiwan Agricultural Research Institute consisted of Z-11-16:AC and Z-11-16:ALD at ratios of 9:1, 8:2, 7:3, 6:4, 1:1, 4:6, 3:7, 2:8 and 1:9. With or without further addition of Z-11-16:OH, the efficacy of these formulations was less than one virgin female moth. This might have been related to the purity of the major components used. |
