Abstract: The control of Cameraria ohridella Deschka and Dimic (Lepidoptera, Gracillariidae) by natural enemies in Europe is poor. Thus, in the past 15 years epidemic population densities of the moth regularly caused a continuous pre‐mature defoliation of horse chestnut trees, Aesculus hippocastanum L..

Since the beginning of the invasion of the horse chestnut leafminer, Cameraria ohridella Deschka and Dimic 1986 (Lepidoptera: Gracillariidae), into Europe over 20 years ago the damage to white flowering horse chestnut trees, Aesculus hippocastanum L (Sapindales: Hippocastanaceae) has remained extensive.

Acta Zoologica Lituanica, 2006
A review of distribution of the horse-chestnut leafminer (Cameraria ohridella) in Lithuania was made on the basis of observations carried out in various Lithuanian cities, towns and settlements in 2002–2006. The first record of the species in Lithuania was made in the Curonian Spit in 2002.

Journal of Applied Entomology, 1999
Abstract: The parasitoid spectrum of the horse chestnut leafminer, Cameraria ohridella, was examined for its adaptation to a newly introduced host. A total of 15 parasitic species belonging to the suprafamilies Ichneumonoidea and Chalcidoidea was reared, all of them are polyphagous and common on other leafminers in Europe. The abundance of the moth and

AbstractThe horse chestnut leafminer, Cameraria ohridella Deschka & Dimic (Lepidoptera, Gracillariidae) spread over the last 10 years from central Europe to western Europe and was observed for the first time in 2000 in the east of France and near Paris.

SummaryAfter its initial discovery in Macedonia in 1985, during the last 19 years the leafminer mothCameraria ohridellahas invaded most of Central and Western Europe. The species, which causes aesthetic damage to horse chestnuts, is generally observed first in highly populated locations before colonizing the countryside. This pattern is consistent with

Journal of Applied Entomology, 2003
Abstract: The internal and external morphology of the female sex pheromone gland in Cameraria ohridella Deschka & Dimic, an European pest on Aesculus hippocastanum L., has been investigated by histological and electron microscopic techniques. The gland consists of a single layer of modified epidermal cells in the dorsal part of the intersegmental ...

Abstract: Qualitative or semi‐quantitative visual assessments are most often used for estimating population size of herbivorous insects. The precision of these estimates, however, is often difficult to establish. A ‘simulation game’ with the horse chestnut leafminer, Cameraria ohridella Deschka & Dimic (Lep., Gracillariidae) shows that visual, semi‐

Journal of Pest Science, 2005
Possible differences in the size and dynamics of the appearance of particular generations of Cameraria ohridella were studied at two city sites of different size and character. The differences in the degree of infestation of Aesculus hippocastanum by the horse chestnut leafminer in the two towns are interpreted as a result of the differences in the ...

Acta Phytopathologica et Entomologica Hungarica, 2009
Authors provide a 6-year study about aspects of development of Cameraria ohridella and its parasitoids in different leaf types of horse-chestnut trees. Investigations were carried out near Hedervar, North-West Hungary between 1999 and 2004.It was ascertained that in large leaves at low foliage levels as well as in large leaves exposed to direct ...
