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.
“It’s a way to deliver different therapeuthics,” Hackett explained, who discussed the technology first tested in citrus and now being studied in many crops. “The Symbiont system promises to transform agriculture and address plant diseases (transmitted by vectors).”
The Fondecyt 2024 project, assigned by Professor Eduardo Fernández, will be implemented nationwide, with around 40 orchards and also with consultants and research centres related to the topic, creating a collaboration strategy directly applicable to their orchards.

Managing processing times means ensuring that fruit moves from harvesting to cooling with as few interruptions as possible. The aim is to reduce waiting, balance capacity across the different stages, prevent accumulation and identify bottlenecks before they compromise fruit condi
