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.
Italy continues to lose positions in the ranking of the largest cherry producers in the world. Currently, the beautiful country is in seventh place, surpassed by Spain and chased by Greece. In just three five-year periods, national production has dropped by 15%.
The surface pitting damage is caused by mechanical damage before and after harvest. The defect only manifests itself after 7-10 days of cold storage, after packing and inspection of the fruit, and has substantial economic implications.
Ultrasound and nanobubble treatments are transforming postharvest cherry management in Chile. Physiological indicators such as pitting, electrolyte leakage and respiration help assess treatment impact and preserve cherry quality for up to 45 days in cold storage.
The use of ultrasound and nanobubbles in post-harvest cherry storage in Chile opens up new possibilities. Physiological indicators such as pitting, electrolyte levels allow the effectiveness of treatments to be assessed and fruit storage to be improved by up to 45 days.
