Drosophila suzukii is a fast-spreading pest invading Europe since 2008. Since 2014, we are catching D. suzukii in our traps in Southern Sweden. As pest on many different soft-skinned fruits like raspberries, blueberries, strawberries, and cherries D. suzukii is a threat to Swedish fruit production. In addition, D. suzukii attacks wild berries with impact on natural ecosystems. It is important to get a better overview of the current state of dispersal in Sweden. Since 2018 we, therefore, involve hobby gardeners as ‘citizen scientists’ that we supply with traps. Returned samples are analyzed in our lab. At 16 out of 22 monitored locations, we identified the presence of D. suzukii and found the fly more widely distributed than previously known. Moreover, flies were commonly found both in private gardens as well as in forest areas.
