The spotted-wing drosophila ( Drosophila suzukii ), is a major pest of soft-skinned fruits. Although insecticides are the primary method of control, alternative management approaches, such as repellents are needed. This study explores the repellent properties of 2-pentylfuran in an apricot-no-choice experiment and in population monitoring traps. It shows that conventional traps supplemented with 2-pentylfuran have reduced catching efficiency (46 %) in the wild and that infestation (number of larvae / fruit) under laboratory conditions is reduced by 78 %. These results corroborate the deterrent nature of 2-pentylfuran and call for further research about the effectiveness and implementation in production systems.
