The integrated protection of horse-chestnuts against horse chestnut leafminer (Cameraria ohridella Deschka & Dimic)

摘要

Horse-chestnut leaf miner (Cameraria ohridella) causes 2 types of leaf damage: (1) reduced photosynthetic area, (2) reduced ornamental value of the plants. The pest does not cause tree death. Thus it is not necessary to used rastic methods of its control. We suggest here a system of integrated control of horse-chestnut leaf miner, aimed to reduce its abundance without the use of chemical methods. This system is mostly based on results of Polish research. We present and describe a diagram of factors involved in implementation of the integrated control of horse-chestnut leaf miner on horse-chestnut (Aesculus hippocastanum). Special attention is paid to the role of agrotechnical practices, which improve tree health.
