Biological, Trophological, Ecological and Control Features of Horse-Chestnut Leaf Miner (Cam?raria ohridella Deschka and Dimic)

The horse-chestnut leaf miner (Cameraria orhidella Deschka & Dimic) is now one of the most dangerous "invasive alien" pests of plantations of bitter chestnut (Aesculus hippocastanum L.) in Ukraine. The factors of absence of natural enemies, the presence of a sufficient amount of fodder base, favorable conditions for reproduction and development have led to the fact that (17 years after the first appearance of this moth) this pest occurs almost throughout Ukraine. It was noted, that Cameraria ohridella first appeared in Kyiv, Ukraine, in 2003. Biological, trophological, and ecological features of Cameraria ohridella in the conditions of the urban phytocenoses in Kyiv (botanical gardens and parks) during 2001–2019 were studied. It was investigated that 77,2–86,2% of total number of mines were found on the lower tier leaves of the chestnut trees. It was established that Cameraria ohridella develop three generations under conditions of the research zone. The fourth generation is possible, but under unfavorable weather conditions in Kiev, most puppae die. The research was carried out in 2008–2019 and it has been determined that increased resistance to Cameraria ohridella have following species: Aesculus × Carnea Hayne, A. octandra Marsh., A. pavia  L., and A. parviflora Walt. It was shown, that in the presence of chestnuts that are damaged by Cameraria ohridella in phytocenoses, it is advisable to treat them with injection of the Imunocomplexon-CH composite into the trunk, which is undergoing the trials stage now. The drug is effective for not less than 3–4 years (efficiency level – 90–100%), which is due to immunization and stimulation of the plant development.
