THE TESTING OF SOME PRODUCTS IN ORDER TO MONITOR THE Cameraria ohridella DESCHKA-DIMIĆ SPECIES (Lepidoptera: Gracilariidae)

The horse-chestnut leaf miner - Cameraria ohridella Deschka-Dimić (Order: Lepidoptera, Family: Gracilariidae) is a serious threat to chestnut trees in cities, as well as a potential threat to biodiversity on the whole. In the period 2016-2017, a research was carried out to monitor and test certain products against the Cameraria ohridella species. These tests were carried out in two locations in Cluj-Napoca and Caracal. Pheromone baits traps were used in three variants (V1, V2, and V3) and were installed in four different places in U.A.S.V.M. Cluj-Napoca Campus and three other places in Constantin Poroineanu Park in Caracal. The synthesis of the pheromone baits was done at Babes-Bolyai University, Cluj-Napoca. During the study it has been noted that the horse-chestnut leaf miner, generally develops three generations/year. In the Caracal area, the maximum population density is reached at the end of July - the first decade of August, and in Cluj-Napoca area in the second decade of August. The total number of adults captured during the period 2016-2017, in Cluj-Napoca is 95756 and 15977 in Caracal.
