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.
Chinese researchers have identified PavUGT48, a gene in sweet cherry that enhances fruit color and quality. The enzyme acts on anthocyanins and amygdalin, paving the way for genetic selection and nutraceutical optimization in commercial cherry varieties.
A recent study from Portugal and Denmark focused on the effects of two biostimulants: glycine betaine and an extract derived from the seaweed Ecklonia maxima. These biostimulants were applied to sweet cherry cultivars “Early Bigi” and “Lapins” grafted onto SL-64 rootstock.
The CTIFL 2026 report presents guidelines to protect cherry trees in France from Drosophila suzukii, combining monitoring, netting, sanitation, biological control and authorized plant protection products for targeted, sustainable crop defense adapted to sites and varieties.
Cherry orchard covers in Chile no longer protect only against rain: they now regulate microclimate, reduce cracking, improve export quality and fruit condition, supporting more stable economic returns in modern orchards exposed to growing climate risk and market pressure.
