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.
In addition to phytosanitary treatments, kaolin and covering the inter-row with Extenday sheets throughout the season as vector control strategies to cover weeds, which are very important for the insect's life cycle, were evaluated.
A five-year study in Southern Russia, Volgograd region, showed how targeted irrigation and balanced nutrition improve vigor, uniformity, and commercial quality of sweet cherry seedlings, while optimizing water use in arid agricultural environments with limited resources.
Cherry production is shaped in autumn: irrigation, stored reserves and dormancy affect bud fertility and winter-chill response. Orchard data help estimate crop loads and plan winter pruning, guiding timely decisions on fruit size and next season’s yield in each orchard.
A Ukrainian study tests hydrocooling in three sweet cherry cultivars and one sour cherry cultivar: water at 1°C with organic acids, cooled to 2°C near the pit. It preserved positive indicators and cut negative impact by up to 49.73%, with effects varying by cultivar.
