“…Scanning parameters of the mass spectrometer includ-ed electron beam ionization voltage of 70 eV, with m/z 40-600 and scanning range of 0.3 s (Duarte et al, 2019). The identification of the compounds was performed using the calculated retention index (van Den Dool & Dec. Kratz, 1963), employing a mixture of linear alkanes (C₇-C₄₀, Sigma Aldrich with purity ≥ 90%) as an external reference in relation to the retention index of the literature (Jackson, 1983;Bonavita-Cougourdan et al, 1991;Brown et al, 1991;Meskali et al, 1995;Lorenzi et al, 1997;Sevala et al, 2000;Howard, 2006;Howard et al, 2006;Kaib et al, 2004;Zhu et al, 2006;Yusuf et al, 2010;Ruther et al, 2011;Tokoro & Makino, 2011;Weiss et al, 2014;Bonelli et al, 2015;Silva et al, 2016;Michelutti et al, , 2018Soares et al, 2017) and associated with the interpretation of the mass spectra obtained from the samples and compared with the databases (NIST21 and WILEY229).…”

As a result of environmental change by anthropic action, animal species that inhabit these areas may suffer the effects of it on their phenotypes as a consequence of adapting to these conditions. In the case of social wasps, cuticular chemical compounds may be influenced, since these vary depending on genetic and environmental factors. However, few studies have investigated the synanthropic effects over the cuticular surface of social wasps. Therefore, the aim of this study was to investigate how cuticular compounds vary according to the different degrees of human activity and test the hypothesis that cuticular compounds of social wasps are affected by the level of anthropic activity in which their nests are found. Data on the cuticular chemical compounds composition of colonies of 3 species of social wasps were used along with the level of anthropization of their nesting sites in four municipalities in the state of Mato Grosso do Sul, Brazil. From the geographical coordinates of the sampling sites, the percentages of urban construction areas, agriculture, water body, vegetation and exposed land were calculated, and the nesting sites of the colonies were classified as more or less anthropized areas. The chemical profile was determined by extraction of cuticular compounds and analyzed by Gas Chromatography coupled to Mass Spectrometer (GC-MS). The results show that the cuticular chemical composition of the individuals of these species is affected by the level of anthropization in their nesting sites, with a qualitative and quantitative variation that must be tied not only to genetic differences, but, above all, to the local environmental conditions to which their colonies are subjected.
