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.
Today's cherry growers are confronted with cherry blight, caused by the bacterium Pseudomonas syringae pv. syringae. In recent years, the disease has appeared more frequently in high and very high density planting and dwarfing rootstocks.
Chile, the world’s top exporter of fresh cherries, is tackling the growing threat of Drosophila suzukii through an advanced strategy that includes the Sterile Insect Technique and a cross-border partnership with Argentina to safeguard fruit quality and global market access.
A study conducted in Kashmir, India, defines an extended BBCH scale for five sweet cherry cultivars. The 50 phenological stages described support more precise orchard management, from flowering and ripening to crop protection and climate monitoring across seasons now.
In Aargau, Switzerland, an agri-photovoltaic system covers more than one hectare of cherry trees, combining power generation, rain protection and shading. Research is assessing its effects on yield, water management, soil conditions, disease pressure and fruit quality.
