Gegen die Miniermotte Cameraria ohridella resistente Aesculus-Arten in Europa – eine Literatur-Übersicht | Aesculus species resistant to the horse-chestnut leaf-miner Cameraria ohridella in Europe: a survey of the literature

Abstract

Owing to urban aesthetics and the loss encountered in nurseries,the question arises of whether it would not make more sense to replace Aesculus hippocastanum with other Aesculusspecies less susceptible to Cameraria ohridella. Two suitable candidates exist to fill this role: A. chinensis and A. x carnea (including two variants). It will, however, be difficult to replace the susceptible horse-chestnut with these Aesculus species. On the one hand, it would mean a loss of biodiversity and, on the other, the risk ensues of a host change to indigenous Acer species. Should this occur, losses could be considerable. An analysis of the host plant's spectrum has so far failed to deliver clear evidence of the provenance. Despite intensive investigation the exact provenance of the moth has still not been identified – even though it has limited the search area.
