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.
The study conducted by the researchers of the Postharvest Research Group of Fruit and Vegetables (Orihuela, Spain) was to examine the effectiveness of preharvest methyl jasmonate (MeJA) treatments in reducing sweet cherry cracking during tree ripening and at harvest.
If we define plant health as a function of primary (growth) and secondary (defence) metabolisms, both share a common pool of cellular energy (CE). The presence of abiotic stress will shift the CE budget, from growth kinetic model to one that is focused on defence mechanism.
Chilean Santina cherries have officially been classified as a low glycemic index (GI=39) food. This result opens new doors for nutrition-focused marketing and reinforces cherries' status as a healthy, smart fruit choice for consumers aiming for a balanced and low-GI diet.
China now absorbs 93% of Chile’s cherry exports, making them the country’s second most exported product after copper. Thanks to direct sea routes, improved logistics, and lower prices, Chile is boosting its position as a global leader in agri-food trade with China.
