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 objective of the German study was to identify the physiological mechanism through which Ca reduces rain macrocracking (rain cracking) in sweet cherry fruit. Results demonstrate that multiple applications of CaCl2 were not effective in decreasing fruit macrocracking.
The outlook for the 2023/24 season is worrying, with an expected 21% decrease in total cherry production due to adverse weather conditions, such as frost and heavy rains, which have affected flowering and fruit set in several countries, particularly Poland and Italy.
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.
