Field cage study highlights safety of classic biological control agent against devastating invasive fruit fly

A field cage study in Switzerland found that a parasitoid was highly specific to the invasive fruit fly Drosophila suzukii, with only 15% parasitism rate. In contrast, non-target species showed a very rare parasitism rate of 0.02%. The results support previous laboratory experiments and suggest low risk for non-target effects.
