The invasive spotted wing drosophila Drosophila 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 24,000 D. suzukii adults 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 of D. suzukii. The highest infestations were found in fruits of the genera Cornus, Prunus, Rubus, Sambucus and Vaccinium as well as in Ficus carica, Frangula alnus, Phytolacca americana and Taxus 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 to D. 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.

铃木果蝇在欧洲用作寄主的非农作物。

入侵斑翅果蝇Drosophila suzukii是亚洲起源的果蝇，是欧洲多种浆果和核果的主要害虫。这种蝇的特征之一是其广泛的寄主范围。更好地了解耕地以外地区的寄主范围对于制定可持续的病虫害综合防治战略至关重要。在意大利，荷兰和瑞士的两年中进行了实地调查。收集了165种潜在寄主植物物种的果实，其中大部分是野生和观赏植物。来自19个科的84种植物中有超过24,000名铃木D.成年成虫，其中38种是非本地的。首次报道了四十二种植物作为铃木D.的寄主。最高的侵扰在属的水果中发现山茱萸，樱桃，悬钩子，接骨木和乌以及在无花果，Frangula桤木，美洲商陆和欧洲红豆杉。根据这些数据，提出了管理方法。水果和果园附近的观赏植物和对冲植物可根据其对铃木D.suzukii的敏感性进行选择。但是，非农作物寄主的广泛可用性和丰富性以及缺乏有效的原生寄生虫表明需要一种区域控制方法。
