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.
Climate change is testing cherry cultivation worldwide. In Washington, experts from 20 countries discussed resilient cultivars, winter nets, covers and predictive models. Focus on China, Chile, Portugal, Germany and California with innovative solutions shaping the future.
Drosophila suzukii shows sustained pressure, with humid Andean foothill areas most exposed and rising damage in key cherry regions. The short harvest window demands strict control, targeted rotations and integrated management to reduce losses and maintain fruit quality.
MSC Invernaderos’ Megatúnel protects cherries and berries from rain and hail. According to the company and Frutotech, it brings early cherry harvests forward by about 15 days, using Gothic arches and ventilation to manage growing conditions without energy-heavy heating.
A dynamic predictive model estimates fungal growth in sweet cherries as temperatures change. Validated using experimental temperature profiles, it could support cold chain management and shelf life estimation, although further testing in commercial conditions is needed.
