Disease: Bactrocera oleae infestation

Effect of Rare, Locally Isolated Entomopathogenic Fungi on the Survival of Bactrocera oleae Pupae in Laboratory Soil Conditions

Researchers tested seventeen types of fungi found in Greek olive groves to see if they could kill olive fruit flies, which damage about 30% of olive crops. They applied the fungi to fly pupae in soil and without soil, then tracked how many flies died and how much fungal growth appeared. Several fungi types, especially Aspergillus flavus and A. keveii, were very effective at killing the flies and could potentially replace harmful chemical pesticides used in olive farming.

Effect of Rare, Locally Isolated Entomopathogenic Fungi on the Survival of Bactrocera oleae Pupae in Laboratory Soil Conditions

Researchers tested seventeen types of fungi as natural pest control for the olive fruit fly, a major pest that damages olive crops in Greece. They found that several fungal species, especially Aspergillus flavus and Aspergillus contaminans, were highly effective at killing fly pupae in soil conditions. These fungi could offer farmers an eco-friendly alternative to toxic chemical pesticides, helping improve olive oil quality while protecting beneficial insects.

Insecticidal Action of Local Isolates of Entomopathogenic Fungi Against Bactrocera oleae Pupae

Olive farmers in Mediterranean countries struggle with the olive fruit fly, which damages olives and reduces oil production. Researchers tested special fungi that naturally infect and kill insects to see if they could control this pest at the soil stage when fly pupae are developing underground. Several fungal species, especially Beauveria bassiana, were effective at reducing survival of emerged adult flies by about 40% compared to untreated flies. This offers a promising natural alternative to chemical pesticides that can harm olive oil quality and lose effectiveness over time.
