Aleochara pseudochrysorrhoa has a glandular complex known as the tergal gland. Generally, the tergal gland secretion (TGS) has been described to have defensive function, but some reports point to a possible secondary function of this complex. For example, the TGS of the related species A. curtula has been demonstrated to possess an important role in intraspecies communication. In this work, we describe the chemical composition of the TGS of A. pseudochrysorrhoa males and females. Eleven compounds were identified based on GC/MS and GC‐FT‐IR analyses, retention indexes and derivatization products. Furthermore, a brief study regarding the biological function of the TGS in mating behavior is provided, in which the stimulation of male grasping response reaction by female TGS proved to be dependent on concentration.

Rove Beetle Aleochara pseudochrysorrhoa (Staphylinidae: Aleocharinae) 的 Tergal 腺分泌物：化学成分和生物学作用

Aleochara pseudochrysorrhoa 有一个腺体复合体，称为 tergal 腺。通常，tergal 腺分泌物 (TGS) 已被描述为具有防御功能，但一些报告指出该复合体可能具有次要功能。例如，相关物种 A. curtula 的 TGS 已被证明在种内交流中具有重要作用。在这项工作中，我们描述了 A. pseudochrysorrhoa 男性和女性的 TGS 的化学成分。根据 GC/MS 和 GC-FT-IR 分析、保留指数和衍生产物鉴定了 11 种化合物。此外，还提供了关于 TGS 在交配行为中的生物学功能的简要研究，其中证明雌性 TGS 对雄性抓握反应的刺激依赖于浓度。
