Dear colleagues, We are pleased to invite you to contribute to our symposium at the upcoming ESEB meeting in Barcelona (August 17 to 22, 2025) entitled "Evolutionary biology meets genetic control" (Symposium 20). For more information, to register and submit your abstract before April 25th, please visit: https://eseb2025.com/ Invited speakers are: Alice Namias, IDEEV, CNRS, Université Paris Saclay Philipp Messer, Cornell University Flo Débarre and Nicolas Rode *S20: Evolutionary biology meets genetic control * keywords: gene drive, /Wolbachia/, Sterile and Incompatible Insect Techniques, selfish genetic elements Genetic control methods are characterized by the release of organisms that are genetically altered to disrupt the reproduction of target pest populations. For example, these methods could be used to either suppress mosquito populations or to reduce their vectorial capacity. Genetic control is deeply embedded in evolutionary theory, involving concepts like the fitness effect of mutations, genetic incompatibilities, population dynamics of selfish genetic elements, etc. The success of these strategies crucially depends on our ability to assess the fitness of released individuals and their impact on the dynamics of target populations. This symposium aims to bring together empiricists and theoreticians working in evolutionary ecology and in genetic control in order to synthetize recent advances in the field. We expect this diversity of backgrounds to foster fruitful discussions that will lead to new research avenues regarding the future of genetic control and will improve our ability to predict the immediate efficacy and long-term sustainability of control strategies.
