Express PRA for Contarinia pseudotsugae


The Douglas-fir needle midge Contarinia pseudotsugae is endemic in Northern America and already occurs in partial areas of Germany and the EU. It is not listed in the Annexes of Directive 2000/29/EC but was included in the EPPO-AlertList in 2016. Contarinia pseudotsugae solely attacks Douglas firs. Due to suitable climatic conditions Contarinia pseudotsugae established outdoors in Germany. An establishment in Central and Northern European EU-Member States is also possible. Notwithstanding that Contarinia pseudotsugae possibly might cause considerable damage mainly in nurseries, young reforestation and in Christmas tree plantings, damage descriptions from the areas where the pest occurs in Germany and other EU Member States are rare. According to actual knowledge Contarinia pseudotsugae is already wide spread in Brandenburg and North-Rhine-Westphalia and is also present in different locations in Rhine-Land Palatinate and BadenWürttemberg. The infestation status in Germany for C. pseudotsugae has to be designated as “present in partial areas”. C. pseudotsugae is already present in partial areas in Germany where partly large areas are infested. The gall midge can effectively be distributed naturally. An eradication or a containment does no longer seem possible. Thus, § 4a of the Plant Inspection Order is no longer applicable; i.e. there is no obligation for notification, control or approval.
