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 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.
A Chinese study on 97 cherry genotypes from 10 countries reveals key genes responsible for malate biosynthesis and transport, the main acid shaping fruit flavor. A breakthrough for breeding programs aiming to enhance cherry quality and consumer appeal.
A University of Hannover study shows that Parka®, a fatty-acid-based cuticle supplement, does not reduce rain-induced cherry cracking. Trials on six cultivars found no effect on cuticle mass, elasticity or fruit water uptake under simulated rainfall conditions.
A 25-year genetic data analysis from the Genome Database for Rosaceae identifies 16 QTL hotspots and 17 syntenic regions across Prunus species. The findings strengthen breeding strategies for peach, sweet cherry and almond, improving fruit quality, yield and disease resistance.
