Horse-chestnut leafminer (Cameraria ohridella Deschka & Dimić, 1986) on yellow buckeye (Aesculus flava) – observations from Munich
Since the beginning of the successful spread of the horse chestnut leafminer throughout middle Europe in the mid-80s, park and city gardeners have been searching for possible alternative tree species that offer a similar decorative value like the white-flowering horse-chestnut (Aesculus hippocastanum). Until now, the red-flowering horse-chestnut (Aesculus x carnea), which is not infested by C. ohridella, has been preferred. The yellow buckeye (Aesculus flava) is also proposed as alter native tree species, since it is thought not to be infested by the leaf-mining moth. Observations from Munich in recent years, however, show that A. flava can serve as host tree for C. ohridella.
