First report of Cameraria ohridella in the United Kingdom
The NPPO of United Kingdom has recently informed the EPPO Secretariat of the occurrence of Cameraria ohridella (formerly on the EPPO Alert List) on Aesculus hippocastanum on its territory.
‘In April 2002 the Forestry Commission of Great Britain published an Exotic Pest Alert (see http://www.forestry.gov.uk/website/pdf.nsf/pdf/horsechestnut.pdf/$FILE/horsechestnut.pdf) warning of the imminent threat from Cameraria ohridella. In July 2002 the first finding of the moth in the UK was confirmed from Wimbledon, South-west London. Surveys of the area, which has significant numbers of Horse chestnut both as parkland and street trees, confirmed that a localised population of C. ohridella was present and had probably passed through one generation already. Surveys were carried out in adjoining London Boroughs and pheromone traps were erected at a number of sites along the southern English coast but no further reports have been received.
The situation of Cameraria ohridella in the UK can be described as follows: Present, found in one location, no official controls in place.’
