Diabrotica virgifera virgifera in France: preliminary results of summer 2009
In France, the preliminary results of trapping studies conducted in summer 2009 showed that Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae – EPPO A2 List) is still present and has been found in new areas. As of 2009-08-20, approximately 300 specimens were caught in 46 communes, belonging to the following 8 departments (in 3 regions): Bas-Rhin, Haut-Rhin (Alsace); Saône-et-Loire (Bourgogne); Ain, Isère, Rhône, Savoie (Rhône-Alpes). Most beetles (approximately 200) were caught in the Alsace region, and the new infested areas found in Bourgogne were close to those in Rhône-Alpes. It is noted that the number of insects caught in 2009 was significantly higher than in previous years.
