Abstract

Social wasps produce various chemical compounds that play roles in prey capture and colony defense. However, knowledge regarding the variation in the composition of these compounds and the influence of the environment on them remains limited, partly due to challenges related to sampling, analysis, and the complexity of the compounds. Therefore, this study evaluated interspecific variation in the venom composition and the importance of environmental factors on intraspecific variation, and the relationship with the age of Polistinae social wasp workers. To achieve this, colonies of Polistes ferreri, P. lanio and P. versicolor, nesting in different environments were collected and analyzed using Fourier transform infrared-photoacoustic spectroscopy (FTIR-PAS). The absorption spectra of the venom were examined to identify the main absorption peaks, followed by the assessment of the intensities and wavenumber positions of these peaks. We found significant differences between species and among colonies of the same species, based on nesting environment and workers age.

蜂科蜂蜂毒液组成的种内和种间差异（膜翅目：蜂科）

群居黄蜂产生各种化合物，在捕获猎物和群体防御中发挥作用。然而，关于这些化合物组成的变化和环境对它们的影响的知识仍然有限，部分原因是与采样、分析和化合物的复杂性有关的挑战。因此，本研究评估了蜂毒组成的种间变异、环境因素对种内变异的重要性，以及蜂毒组成与工蜂年龄的关系。为了实现这一目标，收集了在不同环境中筑巢的Polistes ferreri， P. lanio和P. versicolor的菌落，并使用傅里叶变换红外光声光谱（FTIR-PAS）进行了分析。研究了毒液的吸收光谱，确定了主要的吸收峰，然后对这些峰的强度和波数位置进行了评估。根据筑巢环境和工蚁年龄的不同，我们发现不同物种之间和同一物种的群体之间存在显著差异。

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.
