Les Hyménoptères sociaux (abeilles, fourmis et guêpes) doivent leur succès écologique à une division dutravail marquée par l’existence de castes. Les reines sont spécialisées dans la reproduction, tandis que les ouvrières sont stériles et prennent en charge la construction du nid et sa défense, la récolte de nourriture et l’élevage des jeunes. Le développement d’un œuf femelle en une reine ou une ouvrière est généralement régi par des facteurs environnementaux, tels que la qualité ou la quantité de la nourriture.En réalisant une étude de génétique des populations chez la fourmi Cataglyphis hispanica, nous avons mis en évidence un mode de reproduction inhabituel appelé hybridogenèse sociale. Cette espèce est caractérisée par la co-existence ...
