Spotted wing drosophila (Drosophila suzukii) is a fruit fly native to Japan and Southeast Asia that was first discovered in the USA in 2008. This invasive insect pest attacks a wide range of berry crops including blackberries, blueberries, boysenberries, raspberries, strawberries, and grapes. Wild berry crops, and mulberries and elderberries may also be attacked. In addition to berries, spotted wing drosophila will attack fruit trees such as apples, nectarines, peaches, and plums. Adult populations increase in mid-to-late summer and may remain abundant throughout early fall as berries and fruits ripen. Late-season crops are especially susceptible to attack. Spotted wing drosophila is not a quarantined or regulated pest.
