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 water supply during the fruit-growing season is directly correlated with fruit growth and yield, thereby allowing fruit to reach the appropriate size at harvest. Conversely, excessive preharvest water supplies may negatively impact the fruit storabilty.
The sour cherry (Prunus cerasus) is rapidly spreading in Argentina’s Los Alerces National Park. Its combined sexual and asexual reproduction extends fruiting season and attracts wildlife, increasing its invasive potential and threatening sensitive native species.
Chile, the world’s top exporter of fresh cherries, is tackling the growing threat of Drosophila suzukii through an advanced strategy that includes the Sterile Insect Technique and a cross-border partnership with Argentina to safeguard fruit quality and global market access.
Ultrasound and nanobubble treatments are transforming postharvest cherry management in Chile. Physiological indicators such as pitting, electrolyte leakage and respiration help assess treatment impact and preserve cherry quality for up to 45 days in cold storage.
