Among optical isomers of 3,7-dimethylpentadecan-2-ol (diprionol) acetate or propionate tested as synthetic attractants, the 2S, 3S, and 7S isomers were most effective in attracting the males ofNeodiprion sertifer in the field. The 2S, 3S, and 7R isomers showed weak activity, but the other optical isomers were not attractive. Capillary GC analysis showed that the natural pheromone from body extracts of females was identical with the synthetic acetate of diprionol in its GC behavior. However, the natural pheromone was about 100-fold stronger than the most purified synthetic acetate of 2S,3S,7S-diprionol in the field. As a result of various isomer combination studies, it was found that the acetate of 2S,3R,7R-diprionol, when added to 2S,3S,7S-diprionol preparation at a low concentration, increased the catch by the latter. It was therefore concluded that the above combination of the optical isomers could account for the major sex attractancy in this species.
在测试的 3,7-二甲基十五烷-2-醇（双丙醇）乙酸酯或丙酸酯的对映异构体中，2S、3S 和 7S 异构体作为合成引诱剂对吸引 N.sertifer 雄虫最有效。2S、3S 和 7R 异构体表现出较弱的活性，但其他对映异构体没有吸引力。毛细管 GC 分析表明，从雌性体提取物中的天然信息素在 GC 行为上与双丙醇的合成乙酸酯相同。然而，天然信息素在野外比最纯化的 2S、3S、7S-双丙醇的合成乙酸酯强约 100 倍。通过对各种异构体组合的研究发现，当 2S、3R、7R-双丙醇的乙酸酯以低浓度添加到 2S、3S、7S-双丙醇制剂中时，后者的捕获量增加。因此，可以得出结论，上述对映异构体的组合可以解释该物种的主要性吸引力。
