Abstract

The Neotropical family Serritermitidae is a monophyletic group of termites including two genera, Serritermes and Glossotermes, with different way-of-life, the former being the sole obligatory inquiline among “lower” termites, while the latter is a single-site nester feeding on dry rotten red wood. Like the most advanced termite’s family, the Termitidae, the Serritermitidae is an inner group of the paraphyletic family “Rhinotermitidae”, but unlike the Termitidae, it has been poorly studied so far. In this study, we bring new insights into the chemical ecology of this key taxon. We studied the trail-following pheromone of Serritermes serrifer and we identified (10Z,13Z)-nonadeca-10,13-dien-2-one as the only component of the trail-following pheromone of this termite species, as it is the case in Glossotermes, the other genus belonging to Serritermitidae. This result makes the family Serritermitidae clearly distinct from other Rhinotermitidae, such as the termites Psammotermes and Prorhinotermes, that use (3Z,6Z,8E)-dodeca-3,6,8-trien-1-ol and/or neocembrene as trail-following pheromones.

白蚁的循迹信息素

新热带白蚁科(Serritermitidae)是一个单系的白蚁群，包括Serritermes和Glossotermes两属，它们的生活方式不同，前者是“低级”白蚁中唯一的必栖白蚁，而后者是一个以干燥腐烂的红木为食的单巢白蚁。与最先进的白蚁家族白蚁科一样，Serritermitidae是paraphyletic family“Rhinotermitidae”的内部群体，但与白蚁科不同的是，迄今为止对它的研究很少。在这项研究中，我们对这一关键分类群的化学生态学有了新的认识。结果表明，(10Z,13Z)-nonadeca-10,13-dien-2-one是该白蚁唯一的循迹信息素成分，与其他白蚁属Glossotermes一样。这一结果使得白蚁科与其他使用(3Z,6Z,8E)-十二烷-3,6,8-三烯-1-醇和/或新烯作为追踪信息素的白蚁(如沙母白蚁和原白蚁)明显不同。

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.
