Larval feeding inside the fruit is the primary damage from SWD, causing fruit deterioration. However, oviposition by females can also lead to secondary infection by pathogens and to secondary attacks by other Drosophilaspecies.

There are many hosts suitable for SWD, including cultivated and wild berries (caneberries, blueberries and strawberries) and stone fruits (cherries, peaches, apricots and plums). In Sweden they have been detected in 2016 in cherries and raspberries.
