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.
Scientific studies have shown a decrease in susceptibility of SWD adults to Spinosad, malathion and Spinetoram. In trials in which researchers expected 100% control of SWD, they found a mortality of between 55% and 75%.
‘This season will not be bad for Argentinian exporters. Prices were maintained thanks to the quality of the cherries. We lacked volume, which unfortunately affected producers in Chubut,' said CAPCI Director General Aníbal Caminiti.
In China, consumers judge Chilean cherries beyond origin and size: sweetness, firmness, freshness and consistent quality now shape purchasing decisions. Reviews on RedNote reveal a more informed market, focused on the real value delivered by every box with each purchase.
Chile is preparing a mission to China, Vietnam and Indonesia to streamline fruit exports, reduce phytosanitary barriers and improve logistics. Fresh cherries, cold treatments, fruit fly rules and new market openings across key Asian destinations will now lead the agenda.
