Apparue en Suisse en 2011, la drosophile du cerisier ou Drosophila suzukii est un ra-vageur qui s’attaque aux baies, aux fruits à noyau et aux vignes. Pour faire face aux risques encourus dans les vergers et les vignobles, Agroscope a créé en 2012 en col-laboration avec le FiBL une Taskforce regroupant plusieurs groupes de recherche agronomique. Les résultats de ces travaux font aujourd’hui l’objet de deux nouvelles publications : un numéro spécial de la Revue suisse de viticulture, d’arboriculture et d’horticulture), et un guide technique pour la gestion de Drosophila suzukii dans les cultures de baies.
