Stand der Ausbreitung der Roßkastanienminiermotte, Cameraria ohridella Desch. and Dem. (Lep., Gracillariidae) im Nordrheingebiet
[Occurrence of the horse chestnut leafminer Cameraria ohridella Desch. and Dem. (Lep., Gracillariidae) in the Northrhine area]
Gesunde Pflanzen 52 (2-3), 94-95
Abstract: In the summer 1998 the new horse chestnut leafminer Cameraria ohridella has been found in the region around Bonn and Cologne. A monitoring in 1999 showed that Cameraria-infestation has increased and augmented. Nearly the whole area of the northrhine proved to be infested. The number of ectoparasitic parasitoids in the leafmines is as low as in the formerly infested regions in the south of Europe.
