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.
Is a solution possible? The expert is optimistic and has already taken an important step by defining that one of the important variables affecting post-harvest sensitivity is maturity and therefore its monitoring. But this is not the only challenge.
Peruvian cherries are emerging as a premium export opportunity for China and Asia, supported by early harvests, Chancay logistics and new production areas such as Arequipa, Junín, Cusco and Áncash, strengthening Peru’s agricultural export strategy and trade positioning.
Zadar County is preparing a €250,000 programme to expand Marasca cherry orchards in Dalmatia, supporting new plantings, irrigation and soil preparation, with funding distributed through towns and municipalities between 2027 and 2029 to support local growers in Dalmatia.
A study in Western Poland examines how wild cherry (Prunus avium) responds to temperature and rainfall. Tree-ring growth highlights the species’ potential for dendrochronology, dendroclimatology and climate research, while showing marked differences among local sites.
