The insect cuticle is a barrier against water loss and a source of signals for chemical communication triggered mainly by cuticular hydrocarbons. Knowing that tolerance in social wasps to temperature variations mainly depends on changes in the chemical composition of the cuticle, the objective was to evaluate how high temperatures affect the cuticular hydrocarbon composition of the social wasp Polybia rejecta. The wasps were exposed to a temperature of 40 \u00b0C for 1 h, 3 h, and 6 h following analyses of the cuticular hydrocarbons by GC-MS. The results revealed five long-chain hydrocarbons and one fatty alcohol. The relative percentages to each class of compounds indicated alkanes as the principal component in all samples. Tricosane was only identified after the third hour of exposure, increasing in the sixth hour, suggesting a possible chemical communication mechanism to alert critical situations between individuals. These results open up new avenues of research into insect communication in response to environmental stress.<\/jats:p>","DOI":"10.3390\/d17110766","type":"journal-article","created":{"date-parts":[[2025,11,3]],"date-time":"2025-11-03T18:21:46Z","timestamp":1762194106000},"page":"766","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of Thermal Stress on the Cuticular Chemical Composition of the Amazonian Social Wasp Polybia rejecta (Fabricius, 1798)"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8377-5199","authenticated-orcid":false,"given":"Tatiane Tagliatti","family":"Maciel","sequence":"first","affiliation":[{"name":"Instituto de Bioci\u00eancias, Universidade Federal do Mato Grosso do Sul, Campo Grande 79070-900, MS, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2421-6239","authenticated-orcid":false,"given":"Bruno Corr\u00eaa","family":"Barbosa","sequence":"additional","affiliation":[{"name":"Instituto de Bioci\u00eancias, Universidade Federal do Mato Grosso do Sul, Campo Grande 79070-900, MS, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0945-6894","authenticated-orcid":false,"given":"Samanta","family":"Brito","sequence":"additional","affiliation":[{"name":"Coordena\u00e7\u00e3o de Biodiversidade, Instituto Nacional de Pesquisas da Amaz\u00f4nia, Manaus 69067-375, AM, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3898-5808","authenticated-orcid":false,"given":"Jodieh Oliveira Santana","family":"Varej\u00e3o","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica, Universidade Federal de Vi\u00e7osa, Vi\u00e7osa 36570-900, MG, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1830-725X","authenticated-orcid":false,"given":"Eduardo Vin\u00edcius Vieira","family":"Varej\u00e3o","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica, Universidade Federal de Vi\u00e7osa, Vi\u00e7osa 36570-900, MG, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9060-8815","authenticated-orcid":false,"given":"Marcio Luiz","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Coordena\u00e7\u00e3o de Biodiversidade, Instituto Nacional de Pesquisas da Amaz\u00f4nia, Manaus 69067-375, AM, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2035-2030","authenticated-orcid":false,"given":"Rafael Dettogni","family":"Guariento","sequence":"additional","affiliation":[{"name":"Instituto de Bioci\u00eancias, Universidade Federal do Mato Grosso do Sul, Campo Grande 79070-900, MS, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0477-4252","authenticated-orcid":false,"given":"Jos\u00e9 Eduardo","family":"Serr\u00e3o","sequence":"additional","affiliation":[{"name":"Departamento de Biologia Geral, Universidade Federal de Vi\u00e7osa, Vi\u00e7osa 36570-900, MG, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"93","DOI":"10.1038\/s41586-022-05334-4","article-title":"Extreme escalation of heat failure rates in ectotherms with global warming","volume":"611","author":"Malte","year":"2022","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"6668","DOI":"10.1073\/pnas.0709472105","article-title":"Impacts of climate warming on terrestrial ectotherms across latitude","volume":"105","author":"Deutsch","year":"2008","journal-title":"Proc.
