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 product will be sold at a premium price, 30% higher than standard cherries. The packaging will include the brand and variety name, Tip Top, accompanied by a targeted communication campaign. A landing in the Italian large-scale retail trade is also planned.
A Chinese study developed photodynamic films using chlorogenic acid to extend the shelf life of cherries. This biodegradable, eco-friendly packaging reduces decay and maintains fruit quality. A promising alternative to synthetic preservatives in food storage.
A genomic study identifies 17 HSP70 and HSP90 genes in sweet cherry and explains how they respond to heat and salinity. The results highlight key genes, including PavHSP90-5, that could support breeding of cultivars with resilience to climatic and environmental stress.
A study in southern Chile shows how mineral nutrition, especially the balance between nitrogen and phosphorus, may influence internal browning in Regina sweet cherries, postharvest quality and the fruit’s ability to withstand long storage periods for export markets.
