In Drosophila, heterozygous individuals—carrying different forms of the same coloration gene—exhibit greater phenotypic plasticity (the ability to change color in response to the environment) compared to homozygotes. This enhances genetic diversity within populations and facilitates rapid adaptation to environmental changes. Phenotypic plasticity as a function of genetic polymorphism: thermal dominance reversal in Drosophila species with […]

Nous venons d’apprendre avec une immense tristesse le décès de Pierre Capy, survenu le 3 février. We have just learned with great sadness of the death of Pierre Capy on February 3.Pierre was a geneticist specializing in Drosophila and genome evolution. His research focused on the molecular genetics of transposable elements, their evolutionary dynamics, and

Pierre-Olivier Maquart and Philippe Le Gall conducted an initial mission in November 2025 as part of the FEF-R project: Cooperation for the Protection of Biodiversity in Zimbabwe. Funded by the French Ministry of Foreign Affairs and Europe and the French Embassy in Zimbabwe, the project aims to enhance Zimbabwe’s heritage entomological collections through digitization, 3D
