Ips duplicatus trapped in Belgium
So far, Ips duplicatus (Coleoptera: Scolytidae – EU Annexes) has not been known to occur in Belgium. In summer 2003, pheromone traps specific to Ips typographus were set up in the surrounding of unloading quays in the north of the city of Liège. In August 2003, I. duplicatus adults were caught at Herstal, a locality in which large volumes of Picea logs from Russia (Karelia) and the Baltic countries (where the pest occurs) have frequently been unloaded since 1999. It is considered that the caught insects were introduced with imported logs.
