我们最近报道了在雌性棉铃虫腹尖提取物和处女雌蛾散发的挥发物中鉴定出多达五种信息素成分（Nesbitt 等，1979）。它们是 (Z)-I 1-十六碳烯醛 (I)，这是 Piccardi 等人先前鉴定的主要成分。 (1977, (Z)-11-十六烯1-醇 (II)、(Z)-9-十六烯醛 (III)、十六醛 (IV) 和 1-十六烯醇 (V)。(Z)-9-十六烯醛 (III) 仅在来自马拉维的某些批次昆虫中发现，其含量与 (I) 相似。在马拉维和其他地方用 (Z)-I 进行田间诱捕单独使用 1-十六烯醛 (I) 时，雄性棉铃虫的捕获量较低且不稳定，添加成分 (II)、(III) 和/或 (IV) 对吸引力没有任何一致的影响。然而，这项工作和在澳大利亚进行的其他工作（G.H.L. Rothschild，个人通讯）表明，添加小比例的 (Z)-9-十六烯醛 (III) 增强了主要的吸引力。 Klun 等人 (1979) 还报道，在与棉铃虫密切相关的新世界物种中，除了主要成分 (Z)-11-十六烯醛之外，雌性蛾还产生微量的 (Z)-7 和 (Z)-9-十六烯醛。这些发现可增强后者对雄性蛾的吸引力。促使我们重新检查棉铃虫的信息素系统。在马拉维、印度和苏丹收集了昆虫的幼虫或蛹，然后空运到伦敦。对蛹进行性别鉴定和分离，然后维持相反的光/暗循环（25°和70%相对湿度12小时光照：20°和80%相对湿度12小时黑暗）。按照 Sower 等人 (1973) 和 Klun 等人 (1979) 的描述，在羽化后 2-3 天和进入暗期 5-8 小时，用二硫化碳进行产卵器洗涤液。在填充 Carbowax 20M、OV 225 和 Apiezon L 柱上进行初步分析后。 1979），对玻璃支撑涂层（SCOT）和壁涂层（WCOT）开管柱进行了更详细的分析，并且还在 SCOT 上检查了填充液晶柱（Lester＆Hall，1980）。
We recently reported the identification of up to five pheromone components in abdominal tip extracts of female Heliothis armigera and in volatiles emitted by the virgin female moth (Nesbitt et al., 1979). These were (Z)-I 1-hexadecenal (I), the major component previously identified by Piccardi et al. (1977, (Z)-11-hexadecen1-ol (II), (Z)-9-hexadecenal (III), hexadecanal (IV) and 1-hexadecanol (V). The (Z)-9-hexadecenal (III) was only found in some batches of insects from Malawi when it was present in amounts similar to those of (I). Field trapping in Malawi and elsewhere with (Z)-I 1-hexadecenal (I) alone gave low and erratic catches of male H. armigera moths, and addition of components (II), (III) and/or (IV) did not have any consistent effect on the attractiveness. However, there were suggestions from this and other work carried out in Australia (G.H.L. Rothschild, pers. comm.) that the addition of small percentages of (Z)-9-hexadecenal (III) enhanced the attractiveness of the major component (I). It was also reported by Klun et al. (1979) that in H. zea, a New World species closely related to H. armigera, the female moth produces trace amounts of (Z)-7and (Z)-9-hexadecenal and hexadecanal in addition to the major component, (Z)-ll-hexadecenal. The attractiveness of the latter to male moths was synergised by an appropriate mixture of the minor components. These findings prompted us to re-examine the pheromone system of H. armigera. Insects were collected as larvae or pupae in Malawi, India and the Sudan and flown to London. The pupae were sexed and separated, and then maintained on a reversed light/dark cycle (12 hr light at 25 ° and 70% r.h.: 12 hr dark at 20 ° and 80% r.h.). Ovipositor washings were made in carbon disulphide as described by Sower et al. (1973) and Klun et al. (1979) using female moths 2-3 days after emergence and 5-8 hr into the scotophase. The washings were analysed directly by gas chromatography (GC). After preliminary analyses on packed Carbowax 20M, OV 225 and Apiezon L columns (Nesbitt et al., 1979), more detailed analyses were carried out on glass support-coated (SCOT) and wall-coated (WCOT) opentubular columns, and also on a packed liquid crystal column (Lester & Hall, 1980). Ovipositor washings from moths of Indian origin were also examined on SCOT
