RESISTANCE OF HORSE CHESNUT SPECIES ( AESCULUS L.) TO ORCHID MINER, OR CHESNUT MINING MOTH ( CAMERARIA OHRIDELLA DESCHKA & DIMI Ć )
The resistance of horse chestnut species (6 species) to the mining chestnut moth (Cameraria ohridella) at the collection of the Tsitsin Main Botanical Garden of the Russian Academy of Sciences was studied. The most affected was Aesculus hippocastanum, slightly damaged was A. glabra and A. × hybrida. Caterpillars penetrated in leafs of A. pavia and died. Resistant to the miner were A. octandra and A. × carnea. The stability of the studied species of horse chestnut is carried out by the type of antibiosis. Horse chestnut species resistant to damage by Ohrid miner contain maximum polyphenolic compounds and can be considered as certain factors of plant resistance to mining moths.
