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 PGI project includes numerous cultivars, including as many as 14 native varieties registered and protected by the Regional Germplasm Bank considered to be at risk of extinction, and are also included in the Cesto Pisano list of food and wine products of excellence.
According to the president of the Regulatory Body, "there have been no meteorological problems other than those usual for this time of year in spring. Despite the rains, in full bloom, a harvest of 400 tons of Navalinda and about 2,000 or 3,000 tons of picota is estimated".
A recent study analyzed four sour cherry cultivars, two dark-fleshed varieties, "Heimann R" and "Gorsemska," and two light-fleshed ones, "Montmorency" and "V70142", to determine differences in metabolite composition and antioxidant activity.
The Consorzio Fitosanitario di Modena is particularly engaged in various specialized research activities in favor of cherry producers. Among those, the one related to the annual monitoring of D. suzukii is considered one of the most important to guide technical consultants.
