TI  - Migration und Ausbreitung der Kirschfruchtfliege innerhalb von
Obstanlagen ? Möglichkeit der biologischen Bodenbehandlung
Y1  - 2009///
N2  - The 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.
