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.
Sage Fruit's organic cherries account for about two per cent of the total cherry volume, said Komstadius. "Currently, the volume at the industry level does not seem to be growing, but with organic trends, it is reasonable to think that it will grow in the future."
A study conducted in Japan analyzed the behavior of the Yoshino cherry tree, collecting data from 1948 to 2024. The aim was to understand the relationships between cold exposure, necessary for dormancy release, and heat required for bud development.
A study in three Israeli cherry orchards tests seismic sensors to detect Cerambyx dux larvae, track pest phenology and map infestations. Signals may reveal activity before visible symptoms and help target inspections, but further validation is needed.
In Tasmania, trials by the Tasmanian Institute of Agriculture show GA₃ increases Lapins cherry firmness by about 20%. Application rate and timing affect fruit size and maturity as researchers examine how to balance quality, harvest timing and late-season markets locally.
