Overview

Observation shows Drosophila suzukii increases near semi-natural habitats in berry fields, indicating their role as a refuge and source for the pest and its parasitoids.

Key Points

  • Drosophila suzukii numbers increased in berry fields near semi-natural habitats, indicating NCH's role as a source.
  • Population dynamics were studied over 3 growing seasons, assessing the impact of proximity to non-crop habitats.
  • Females showed greater dispersion from semi-natural habitats into berry fields, particularly in spring and fall.
  • Parasitism rates of Drosophila suzukii pupae by Trichopria drosophilae were consistent across both habitats, showing easy dispersal.
