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 C. Aubert and colleagues from the Centre Technique Interprofessionnel des Fruits et Légumes (France) investigates the impact of hot water treatments (HWT) on the quality and preservation of sweet cherries, focusing on two cultivars: Balrine and Regina.
‘It was a very good year. We had a high quality harvest and this was recognised by the market,' commented Aníbal Caminiti, director of CAPCI. ‘At the national level, we can say that we are about to reach 6,000 tonnes of exported cherries.
A study from Miguel Hernández University in Alicante investigates the effect of melatonin applied before and after harvest on 'Sunburst' cherries. Results show a 29% rise in anthocyanins and a 5x increase in endogenous melatonin after 21 days at 2 °C in cold storage.
In Quincy, Washington, cherry growers Dale and Brandon Goldy bring orchards into production by the third leaf through precise pruning, scoring and plant growth regulators. Their system turns vigor into fruiting wood, reducing blind wood and improving yield and canopy light.
