Strategien zur Bekämpfung der Roßkastanienminiermotte (Cameraria ohridella) im urbanen Bereich

Strategies to control the horse chestnut leafminer (Cameraria ohridella) in urban environments. The continuous epidemic infestation of horse chestnuts by C. ohridella is a serious aesthetic and economic problem in urban environments. The project "BerlinCam", therefore, aims to develop control measures which meet the special needs of urban plant protection. Chemical treatments using a recently developed application method achieved a substantial reduction of the infestation level of horse chestnut leaves by the pest insect. Easily practicable and safe depot-applications of systemic insecticides turned out to be effective in killing preimaginal stages of the leafminer on young trees. Questions regarding potential environmental risks and economic practicability of these methods will be answered in the next two years of the project. So far, chemical products are not registered in Germany.
