Abstract
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‑1) 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.
