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.
On 20 December in the area of Río Claro, in the region of Maule, a trial of the new varieties Sweet Saretta® and Sweet Stephany® was visited with fruits close to harvest, which showed a size of around 30 mm and soluble solids around 20°brix.
The global cherry exports have shown a trend of sustained growth in recent years, rising from $3.089 billion in 2019 to a peak of $4.514 billion in 2022, mainly due to the strong demand from Asian markets like China. In 2023, however, these exports saw a 13.5% decline.
Fruit cracking leads to significant economic losses in Mediterranean orchards. Advanced sensing technologies and precision agriculture now allow growers to detect early stress signals, reduce fruit splitting, improve resource efficiency and enhance overall crop sustainability.
Cherry season exposes the limits of self-care as a safety model. Is it a personal duty or a sign of poor risk management? When risks increase, only structured systems—not individual willpower—can ensure health and safety for all workers in the field.
