Abstract: The horse chestnut leaf miner (Cameraria ohridella Deschka and Dimic) is widespread in Germany. Anthropogenic transport of adults and pupae by land and water vehicles plays an important role, as well as the spread by aerial plankton. The development of the pest population passes through several generations per year which may overlap to a large extent. The pupae may lie dormant for several years. Certain information is still missing on the physiological reactions of trees due to infestation. The appearance of secondary damage on infested trees due to wood and root-inhabiting fungi has to be considered more seriously in the future. Until now medium-range damage, such as reduced leaf size, emergency flowering in the autumn, reduced formation of fruits and year rings has been observed. Infestation may be reduced to a certain extent by using sticky trap rings around the trunks, but not with sticky sheets. Mass trapping using pheromone traps is not a suitable means for direct control. Pheromone traps, however, are suitable tools for monitoring purposes, particularly in combination with certain phenological stages. Natural enemies, all of which are polyphagous species, show rates of parasitization between 5 and a maximum of 20%. This is not sufficient for controlling the pest effectively. Progress could be made by detecting the natural habitat of the horse chestnut leaf miner in order to identify, and possibly use, natural enemies.
