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.
Is a solution possible? The expert is optimistic and has already taken an important step by defining that one of the important variables affecting post-harvest sensitivity is maturity and therefore its monitoring. But this is not the only challenge.
Despite a slight 1% drop in shipments compared to the previous year, over 413,000 tonnes of cherries were shipped worldwide. The Far East was confirmed as the main destination, with China taking 97% of the total.
A study on ‘Meizao’ sweet cherries shows that foliar 5-ALA at 100 mg/L increases fruit weight, color, sugars, nutraceutical compounds and aroma complexity by improving photosynthetic efficiency and stimulating the biosynthesis of secondary metabolites in the fruit itself.
A 12.5% US tariff on Chilean cherries is squeezing margins and slowing diversification beyond China. Exporters are responding through bilateral talks, more efficient logistics, premium-grade fruit and faster growth in Vietnam, India, Indonesia and South Korea in 2026.
