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 2025 Spanish cherry season was marked by extreme weather, reduced volumes, and strong domestic demand. Despite initial quality issues, high prices and falling production in other countries helped Spain strengthen its role in Europe and look ahead to China.
The problem does not only concern Michigan. According to economist Ernie Goss, farms across the country are facing similar difficulties, with some regions, such as the Midwest, facing the onset of an agricultural recession.
Spring rains in Chile have split early cherries in the north, while damage in O’Higgins, which accounts for over 80% of production, remains marginal so far. Growers are monitoring fungal disease, saturated soils and potential impacts on Chile’s 2026/27 cherry crop.
Da 14 anni, il PMGCe della PUC in Cile seleziona varietà precoci di ciliegio, a basso fabbisogno in freddo e resistenti a caldo, siccità e cracking. Tre selezioni avanzate e 1.000 individui sono valutati in quattro siti: l’obiettivo è registrare una varietà entro il 2030.
