First Experimental Release of Parasitic Asian Wasp to Control Spotted-Wing Drosophila
The invasive spotted-wing drosophila (SWD) is a devastating pest in berry, stone fruit and grape crops. A natural antagonist from the fruit fly’s area of origin in East Asia is now due to be released in Switzerland for the first time by Agroscope and CABI.

The invasive spotted-wing drosophila (SWD) is a devastating pest in berry, stone fruit and grape crops. A natural antagonist from the fruit fly’s area of origin in East Asia is now due to be released in Switzerland for the first time by Agroscope and CABI. The experimental releases in the Cantons of Jura and Ticino aim to clarify whether this parasitic wasp can become established in Switzerland to regulate the SWD population and reduce production losses.
This fly damages ripe fruits, berries and grapes . Agroscope researchers are proposing different fighting methods.
