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 study conducted by the researchers of the Postharvest Research Group of Fruit and Vegetables (Orihuela, Spain) was to examine the effectiveness of preharvest methyl jasmonate (MeJA) treatments in reducing sweet cherry cracking during tree ripening and at harvest.
Countries such as Serbia can successfully utilise waste by transforming it into biochar. Due to its special structure, biochar is able to adsorb and immobilise enzymes useful for the degradation of toxic substances.
Chile’s cherry industry is facing a severe crisis driven by oversupply, falling prices and quality problems. Jordi Casas outlines a path forward: reduce planted area, diversify export markets, invest in genetics and improve orchard management to restore profitability.
Trials in Tasmania show that Eristalis tenax hoverflies, used alongside honeybees, can improve fruit set and sweet cherry yields. Active in cool and wet weather, these alternative pollinators could support more reliable orchards and reduce risks linked to varroa mite.
