Abstract

It is a commonly known fact that all ground beetles possess abdominal pygidial glands with relatively similar gross structure and function among species. Still, morphology of the glands and composition of their secretions have not been studied in most ground beetle species. These exocrine glands and their products are mainly associated with defence in natural environments. In this paper, we studied three predatory ground beetle species of the genus Carabus Linnaeus, 1758, namely C. (Archicarabus) montivagus Palliardi, 1825, C. (Megodontus) caelatus Fabricius, 1801, and C. (M.) violaceus Linnaeus, 1758, to identify chemical components of their pygidial gland secretions. Altogether, 10 carboxylic acids were isolated from the analysed secretions [two from the secretion of C. (A.) montivagus, 10 from that of C. (M.) caelatus, and nine from that of C. (M.) violaceus]. The finding of 2-hexenoic acid in the secretion of C. (M.) caelatus is the first finding of it within the entire subfamily Carabinae. In addition, we also analysed the morphology of glands of the species C. (M.) violaceus.

林菖蒲(鞘翅目:菖蒲科)乳腺分泌物:三种释放的化学物质

众所周知，所有的地面甲虫都有腹部的pygidial腺体，其大体结构和功能在物种中相对相似。然而，大多数地面甲虫种类的腺体形态和分泌物组成尚未被研究过。这些外分泌腺及其产物主要与自然环境中的防御有关。本文对1758年Carabus Linnaeus属的3种掠食性地甲虫(c (Archicarabus) montivagus Palliardi, 1825年，c (Megodontus) caelatus Fabricius, 1801年和c (m) violaceus Linnaeus, 1758年)进行了pygidi腺分泌物化学成分的研究。从分析的分泌物中共分离出10种羧酸，其中2种来自montivagus, 10种来自c.m . caelatus, 9种来自c.m . violaceus。在caelatus的分泌物中发现2-己烯酸是在整个Carabinae亚科中首次发现的。此外，我们还分析了c (m) violaceus的腺体形态。

期刊介绍： It is the aim of Chemoecology to promote and stimulate basic science in the field of chemical ecology by publishing research papers that integrate evolution and/or ecology and chemistry in an attempt to increase our understanding of the biological significance of natural products. Its scopes cover the evolutionary biology, mechanisms and chemistry of biotic interactions and the evolution and synthesis of the underlying natural products. Manuscripts on the evolution and ecology of trophic relationships, intra- and interspecific communication, competition, and other kinds of chemical communication in all types of organismic interactions will be considered suitable for publication. Ecological studies of trophic interactions will be considered also if they are based on the information of the transmission of natural products (e.g. fatty acids) through the food-chain. Chemoecology further publishes papers that relate to the evolution and ecology of interactions mediated by non-volatile compounds (e.g. adhesive secretions). Mechanistic approaches may include the identification, biosynthesis and metabolism of substances that carry information and the elucidation of receptor- and transduction systems using physiological, biochemical and molecular techniques. Papers describing the structure and functional morphology of organs involved in chemical communication will also be considered.
