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，在田間比較具誘引小菜蛾雄蛾之效力。三種配方中，主成分Z-11-16：Ac+7-11-16：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-9-14：AC（1：1：0.01）之配方則 有抑制誘雄之作用。另以Z-11-16：AC及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。

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-ll -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 formulation. The nine formulations provided by Taiwan Agricultural Research Institute consisted of Z-ll-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.
