In 1998-1999 a detection survey on the presence of the western corn rootworm (WCR) Diabrotica virgifera virgifera Le Conte was conducted in Austria, Germany, France, Slovakia and Slovenia. In these countries, the primary monitoring tool was the Hungarian pheromone trap. According to the results, no WCR adults were detected in these countries. It is assumed that Austria, Germany, France, Slovakia and Slovenia are probably free of this destructive maize pest.
