USDA: odour research could solve the fight against Drosophila suzukii

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.
