Spotted Wing Drosophila in Ontario
Spotted wing drosophila (SWD) is an invasive vinegar fly that has the potential to cause extensive damage to many fruit crops. Surveys coordinated by OMAFRA indicate SWD has spread to most fruit producing regions in Ontario.
SWD has become a chronic pest in berry and tender fruit crops in Ontario. Early detection and management are required to limit economic damage.
