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.
Chitosan-coated silver nanoparticles (AgChNPs) show high efficacy against Drosophila suzukii, a major fruit pest. This sustainable biotechnological solution reduces adult emergence, reproduction, and causes morphological damage, offering a valid alternative to insecticides.
In Chile’s cherry sector, oversupply and rising costs are reshaping the market. According to Raimundo Cuevas, not all orchards will survive: higher productivity, new varieties and a redefinition of growing areas will be essential to maintain profitability in the coming years.
In Spain’s Jerte Valley, genomic selection is speeding up cherry breeding: Cicytex and Agrupación de Cooperativas Valle del Jerte will work through 2030 on 1,000 trees and around 110 varieties to identify fruit quality, ripening and market suitability earlier using DNA.
Effective cherry blossom management improves pollination, fruit set and size. From beehives, Bombus colonies and pollen to auxin, cytokinin and fungicide applications, these key strategies help support yield, fruit quality and crop health throughout flowering season.
