Overview

Behavioral assays demonstrate enhanced attraction to Drosophila suzukii-infested fruits, indicating potential for biocontrol strategies.

Key Points

  • Trichopria drosophilae is attracted to volatile organic compounds emitted by Drosophila suzukii-infested cherries.
  • Infested fruits showed elevated levels of key attractants like ethyl acetate and isoamyl acetate compared to healthy fruits.
  • Electrophysiological assays identified ethyl acetate as a potent stimulant for foraging behavior in T. drosophilae.
  • These findings suggest that specific semiochemicals could optimize biocontrol strategies against the invasive D. suzukii pest.
