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.
"One of the problems that the PDO has to face every year is the marketing of normal cherries from which the stalk is removed to pass them off as picota cherries,' says Fátima López-Santamaría, PDO Cereza del Jerte technician, 'using the PDO trademark illegally.
The nutritive value of fruits is directly related to their quality, which can be compromised by numerous adversities both in the field and postharvest. Various fungi and bacteria can cause disease on cherry trees.
In Chile, attention is growing around contractual risks in the cherry industry. Lawyer Álvaro Jofré examines advances, guarantees, due diligence, penalties and foreign investment, outlining safeguards that can reduce disputes, financial losses and legal exposure abroad.
The Corette® series introduces low-vigor cherry rootstocks for high-density orchards. Trials in Spain, Italy and across Europe are assessing yield, adaptation to calcareous soils, protected cultivation, lower winter chilling requirements and mechanization strategies.
