Dear all, We are organising a thematic session on evolutionary genetics as part of the XIII European Congress of Entomology from June 29 to July 3 2026 in Tours, France (www.ece2026.org). This session includes six symposia: - Eco-evolutionary dynamics of sexual selection and sexual conflicts - keynote speaker: Pau Carazo (University of Valencia, Spain). - Genomics and evolutionary novelties. - Unraveling phenotypic plasticity: Molecular bases to evolutionary outcomes - keynote speaker: Patricia Beldade (University of Lisbon, Portugal). - Eco-evolutionary dynamics of host-microbiome interactions - keynote speaker: Marjolein Bruijning (University of Amsterdam, Netherlands). - Genetic variation and selection in insect populations - keynote speaker: Kelley Leung (Wageningen University, Netherlands). - Symbionts and insects as holobionts - keynote speaker: Hassan Salem (Max Planck Institute for Biology, Tübingen, Germany). We welcome abstract submissions for oral presentations and posters (submission deadline: 15/12/2025). Information about the congress and our thematic sessions can be found on the website (www.ece2026.org).
