摘要

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.
