Spotted Wing Drosophila, a well-known pest that infests ripe, ready-to-eat fruit, poses a significant threat to farmers because it is very difficult to control with standard pesticides. A new approach to tackling this pest involves manipulating the behavior of these insects by disguising healthy fruit as if it were infected with an unappealing pathogen.
By studying the specific odors emitted by infected fruit, researchers have identified the chemicals that repel the flies when applied to healthy fruit and are developing a slow-release device to disperse these fruity odors in the field, ensuring that they do not come into direct contact with the fruit. This method provides a new tool to help farmers protect their crops without relying exclusively on insecticides.
The surface pitting damage is caused by mechanical damage before and after harvest. The defect only manifests itself after 7-10 days of cold storage, after packing and inspection of the fruit, and has substantial economic implications.
The decision was motivated by the desire to have more control over product quality and to reduce financial risks. "We will no longer buy fruit as in the past," said Gökyigit.
In Aragon, cherry growers receive just €0.50 per kilo while labor alone costs €1.20. ARAGA warns that unsustainable prices, adverse weather and widening supply-chain margins are threatening farms, rural communities and the long-term future of the region’s fruit sector.
Greece’s cherry season is producing record volumes in Pella, but low prices, foreign competition, labour shortages and packaging problems are squeezing growers’ and packers’ margins, despite the excellent quality of fruit shipped to export markets across Central Europe.
