Organic EprintsMigration und Ausbreitung der Kirschfruchtfliege innerhalb von Obstanlagen – Möglichkeit der biologischen BodenbehandlungClaudiaDanielauthorEricWyssauthorThe European cherry fruit fly (Rhagoletis cerasi) is the only pest insect which makes a insecticide treatment of cherry fruit necessary. With regard of residue free cherries a biocontrol method for R. cerasi by soil applications seems attractive. However, soil treatments can only be effective if the migration of flies is low. In order to examine the potential of soil treatments and to understand the dispersal behaviour of R. cerasi in orchards, experiments using nettings to cover the soil were conducted. The experiments were arranged in commercial, organically managed orchards. The nettings reduced fruit infestation by 90%. In addition, it was shown that the flies move only very short distances (less than 5 m) within orchards. Thus, soil treatments are an interesting strategy to control R. cerasi in extensively managed orchards.Crop health, quality, protection2009Conference paper, poster, etc.
