摘要

Two components, trans-11S,12S-epoxy-(6,9)-heneicosadiene and (Z)-6- heneicosen-11-one, were identified from the sex pheromone glands of Orgyia postica (Walker) in Taiwan by gas chromatography-mass spectrometry. The average amounts of trans-11S,12S-epoxy-(6Z,9Z)-heneicosadiene and (Z)-6- heneicosen-11-one in individual virgin female glands were 30.7 ± 3.3 and 8.7 ± 0.6 ng/female, respectively, and the ratio of the amount of the two components was 3.6 ± 0.3. Using the single component of (Z)-6-heneicosen- 11-one, no moths were caught in the field. Using the combination of trans-11S,12S-epoxy-(6Z,9Z)-heneicosadiene and (Z)-6-heneicosen-11-one at a ratio found in the gland extract of 4: 1, significantly more males were caught than with trans-11S,12S-epoxy-(6Z,9Z)-heneicosadiene alone.

用氣相層析質譜儀以及氣相層析儀鑑定台灣小白紋毒蛾的性腺體中兩種成分，trans-11S,12S-epoxy-(6Z,9Z)-heneicosadiene與(Z)-6-heneicosen-11-one，在處女蛾腺體的平均含量分別為30.7±3.3及8.7±0.6 ng，而二者的含量比例為3.6±0.3.單獨用trans-11S,12S-epoxy-(6Z,9Z)-heneicosadiene可以誘到雄蟲，單獨用(Z)-6-heneicosen-11-one做誘餌，無法抓到雄蛾，但是將兩種成分，用4：1的比例做誘餌，誘到的雄蟲比單獨用trans-11S,12S-epoxy-(6Z,9Z)-heneicosadiene誘到的多。
