Cameraria ohridella continues to spread in Europe
The EPPO Secretariat has browsed again through the literature and Internet and found the following new data concerning Cameraria ohridella (EPPO Alert list). In addition, the French NPPO informed the EPPO Secretariat that the horse chestnut leafminer has been found in France.
In Belgium, C. ohridella was found in Brussels in July 2000 on horse chestnut (Aesculus hippocastanum). Damage has also been observed on maple (Acer platanoides) (Web site of Bruxelles et Environnement).
In France, C. ohridella was found in 2000 in the eastern part (Alsace, Lorraine and Franche Comté regions), in Ile de France region (Yvelines département) and in Rhône Alpes region (Rhône département).
In 1999, the presence of C. ohridella on horse chestnut was reported in the Netherlands (Stiger ; de Haas, 1999).
C. ohridella was reported for the first time in Poland in 1998 on horse chestnut, in the Wroclaw district, southern Poland (Labanowski ; Soika, 1998).
The recent presence of C. ohridella in Switzerland is mentioned by Skuhravy (1999). It is also noted that C. ohridella occurs in Bosnia ; Herzegovina and Yugoslavia (Serbia), but these are not recent findings.
A map displayed on the web site of the Institute of Organic Chemistry and Biochemistry, Department of Natural Products, Prague (CZ), shows that C. ohridella occurs in Albania, Bulgaria and Romania.
Concerning host plants, C. ohridella can also develop on Acer pseudoplatanus and A. platanoides (Gregor et al., 1998).
