Abstract

The female sex pheromone of Grammodes geometrica (Lepidoptera: Erebidae: Erebinae) was identified as a 2:100:4 mixture of (3Z,6Z,9Z)-3,6,9-icosatriene (T20), (3Z,6Z,9Z)-3,6,9-henicosatriene (T21), and (3Z,6Z,9Z)-3,6,9-tricosatriene (T23) through chemical and electrophysiological analyses of female gland extracts. T23 is a novel sex pheromone component in Erebinae species. Field trapping tests demonstrated optimal male captures in attractant-baited traps when using a 2:100:4 blend of T20, T21 and T23, with a significant decrease in captures observed when T20 or T23 were removed from the full blend. Traps were set in early August, but males began to be captured in early September. The seasonal prevalence showed a bimodal peak, occurring on September 11 and October 9. These findings provide valuable insights into the chemical communication and ecological dynamics of this species within the subfamily Erebinae.

Grammodes Geometrica（鳞翅目：Erebidae：Erebinae）雌性信息素的鉴定。

经鉴定，Grammodes geometrica（鳞翅目：蜾蠃科：蜾蠃属）的雌性信息素为 2:100：通过对雌性腺体提取物的化学和电生理分析，确定了(3Z,6Z,9Z)-3,6,9-二十碳三烯(T20)、(3Z,6Z,9Z)-3,6,9-henicosatriene(T21)和(3Z,6Z,9Z)-3,6,9-三碳三烯(T23)的 2:100:4 混合物。T23 是鳗鲡物种中一种新的性信息素成分。野外诱捕试验表明，当使用 2:100:4 的 T20、T21 和 T23 混合诱饵诱捕时，雄性捕获量最佳，而当从全部混合诱饵中去除 T20 或 T23 时，捕获量显著下降。诱捕器于八月初设置，但九月初开始捕获雄性。季节性捕获率呈现双峰，分别出现在 9 月 11 日和 10 月 9 日。这些研究结果为了解该物种的化学通讯和生态动态提供了宝贵的信息。

期刊介绍： Journal of Chemical Ecology is devoted to promoting an ecological understanding of the origin, function, and significance of natural chemicals that mediate interactions within and between organisms. Such relationships, often adaptively important, comprise the oldest of communication systems in terrestrial and aquatic environments. With recent advances in methodology for elucidating structures of the chemical compounds involved, a strong interdisciplinary association has developed between chemists and biologists which should accelerate understanding of these interactions in nature. Scientific contributions, including review articles, are welcome from either members or nonmembers of the International Society of Chemical Ecology. Manuscripts must be in English and may include original research in biological and/or chemical aspects of chemical ecology. They may include substantive observations of interactions in nature, the elucidation of the chemical compounds involved, the mechanisms of their production and reception, and the translation of such basic information into survey and control protocols. Sufficient biological and chemical detail should be given to substantiate conclusions and to permit results to be evaluated and reproduced.
