Drosophila suzukii continues to spread in France
In France, surveys conducted in 2011 on Drosophila suzukii (Diptera: Drosophilidae – EPPO A2 List) showed that the pest occurred in all regions where it was detected in 2010 (Aquitaine, Corse, Languedoc-Roussillon, Midi-Pyrénées, Provence-Alpes-Côte d'Azur, and Rhône-Alpes) and that it had spread to four new regions. In 2011, it was detected for the first time in Lorraine (Meuse department), Ile-de-France (Seine-et-Marne, Yvelines, Val-de-Marne), Pays-de-la-Loire (Maine-et-Loire) and Poitou-Charentes (Deux-Sèvres and Charente-Maritime). Severe damage was observed, mainly on cherry (Prunus avium), strawberry (Fragaria ananassa), raspberry (Rubus idaeus), blackberry (Rubus fruticosus) and blueberry (Vaccinium myrtillus). Damage was also observed on peaches and apricots (Prunus persica and P. armeniaca) but to a lesser extent.
The situation of Drosophila suzukii in France can be described as follows: Present, first reported in spring 2010, it occurs in Aquitaine, Corse, Ile-de-France, Languedoc-Roussillon, Lorraine, Midi-Pyrénées, Pays-de-la-Loire, Poitou-Charentes, Provence-Alpes-Côte d'Azur and Rhône-Alpes, under official control.
