Distribution details in Belgium
Current pest situation evaluated by EPPO on the basis of information dated
The species is recorded as casual in Belgium in 1999 in the Ghent port area (a single plant) and in 2013 in the port of Roeselare (several individuals). It is suspected that these plants did not maintain (no ripe fruits had been observed in November 2013). In Ghent, the species was found at the Ghent train terminal where all kinds of cereals are introduced, and it was found among typical soybean aliens, it is therefore suspected that P. hysterophorus may have been introduced as a contaminant of cereals or of soybean consignments. In Roeselare, it was found on rough ground surrounding a petfood mill, it is then suspected that the species could have been introduced as a contaminant of birdseed or other petfood.
