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 SIMKEF model, which aims to predict and control the insect using models based on temperature data, combines various climatic and biological parameters to estimate the (daily) probability of occurrence of the pest.
Interestingly, cherries from trees with a trunk height of 60-65 cm retained their quality for a longer period compared to those from other heights, showing less weight loss and maintaining a higher level of firmness and soluble solids.
PGPR applied to Gisela 6 rootstock improve rhizosphere fertility, nutrition and root development in sweet cherry. Co-inoculation with Pantoea ananatis D1-28 and Bacillus aryabhattai LAD emerges as a sustainable strategy for efficient roots and more vigorous plants.
Early cherries in California offer strong market potential for growers, but success depends on adapted genetics, protected agriculture and climate risk management to secure fruit quality, consistency and profitability in the San Joaquin Valley, even in unstable seasons.
