The cultivation of horse chestnut in Europe has been made significantly more difficult by the occurrence of leaf miner Cameraria ohridella. It was identified for the first time in Macedinia in 1986. Since then, its range has widened rapidly so that today it is distributed throughout the Central and a greater part of the South and East Europe. Cameraria ohridella usually develops three overlapping generations. For this reason, its adults appear from mid April to the end of October. The females deposit eggs on adaxial leaf, the hatched caterpillars bore in the leaf and chew transparent mines of irregular form. It hibernates in the pupal stage in the mines of the fallen leaves. The suppression of Cameraria ohridella is best if the fallen leaves are collected in the autumn and burned. However, if the leaves are not collected, the control can also be performed by the application of insecticides during the period of its swarming.
