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.
Dutoit, one of the leading companies in the fresh produce business in South Africa, is accelerating its investments in the production, packaging, and export of cherries, a new cycle of investments that quickly expanded to a total area of 300 hectares across 6 different farms.
The purpose of the study conducted at Hitit University, Turkey, was to determine whether treated and untreated cherries could be distinguished from one another based on their odour clues, also investigating whether it was possible to recognize the excessive presence of pesticide.
Thermosonication improves postharvest storage of sweet cherries by reducing decay, weight loss and oxidation. The treatment preserves firmness, vitamin C and flavonoids, while strengthening antioxidant defenses and maintaining fruit quality for 12 days at 4 °C.
The Jerte Cherry PDO closes a very positive season, with 5 million kg of cherries and 2.5 million kg of certified picota. High quality, new varieties and strong European sales reinforce the value and identity of the local cherry supply chain, protected by the Jerte PDO.
