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.
A study in China clarifies how ethylene and PavSPL7 regulate sweet cherry softening. This transcription factor limits cell wall degradation, improving fruit firmness, postharvest quality and potential shelf life for more efficient cherry supply chains worldwide.
The 2025 cherry season in Washington exposed a deep imbalance between quality and profitability: excellent fruit but the lowest prices in two decades. Early harvest, excess volumes, and competition from California undermined market performance for growers.
A study of 27 Hungarian and international sour cherry cultivars examines genetics, anthocyanins and fruit pigmentation. Results show that fruit colour depends mainly on gene expression and regulators such as MYB10, rather than on overall genetic relatedness among cultivars.
In Chile, effective cherry tree branching can accelerate fruit production and improve yield potential. Hydrogen cyanamide, Promalin, gibberellic acid and targeted bud treatments help stimulate healthy, uniform lateral branches and support efficient orchard development.
