title: Non-crop plants used as hosts byDrosophila suzukiiin Europe.
abstract: The invasive spotted wing drosophilaDrosophila suzukii, a fruit fly of Asian origin, is a major pest of a wide variety of berry and stone fruits in Europe. One of the characteristics of this fly is its wide host range. A better knowledge of its host range outside cultivated areas is essential to develop sustainable integrated pest management strategies. Field surveys were carried out during two years in Italy, the Netherlands and Switzerland. Fruits of 165 potential host plant species were collected, including mostly wild and ornamental plants. Over 24,000D. suzukiiadults emerged from 84 plant species belonging to 19 families, 38 of which being non-native. Forty-two plants were reported for the first time as hosts ofD. suzukii. The highest infestations were found in fruits of the generaCornus,Prunus,Rubus,SambucusandVacciniumas well as inFicus carica, Frangula alnus, Phytolacca americanaandTaxus baccata.Based on these data, management methods are suggested. Ornamental and hedge plants in the vicinity of fruit crops and orchards can be selected according to their susceptibility toD. suzukii. However, the widespread availability and abundance of non-crop hosts and the lack of efficient native parasitoids suggest the need for an area-wide control approach.
