Key points

  • A new, shelf-stable yeast "supernatant" has been proven effective at attracting the destructive spotted-wing drosophila fruit fly.
  • This "attract-and-kill" method can protect valuable crops like cherries, berries, and grapes with more precision than broad-spectrum insecticides.
  • The new technique specifically targets the pest fly without causing additional harm to beneficial parasitoid wasps, a key ally for sustainable farming.
  • This innovation could lead to more stable fruit supplies, potentially curbing price increases caused by crop loss.
  • The use of a yeast supernatant instead of a live culture represents a significant logistical and handling improvement for farmers.
