A method for creation of a complex map of potentially low, average and high phytosanitary risk for cultivation of fruit crops by unification of initial maps with AxioVision program is offered for the first time. Initial maps of harmfulness zones executed in a uniform format were selected from the project Agroatlas, which were compiled for 50 species of specialized pest arthropods that had the greatest economic value in the territory of the former Soviet Union during the last decades.
The cherrybark moth Enarmonia formosana (Tortricidae) causes significant damage to the trunks of fruit crops ( hawthorn, apple, cherry, pear, etc.) in the southern regions of Russia and the countries of southern and central Europe. The phenology of the cherrybark moth in the Leningrad Region has not been studied enough, which determined the purpose of this study. Pheromone monitoring of the flight dynamics of the Enarmonia formosana was carried out in the experimental orchard of St. Petersburg State Agrarian University (Pushkin district) and in the orchard Skrebovo (Luga district) in 2008-2009 and 2020-2021. Pheromone materials produced by JSC Shchelkovo Agrokhim (Shchelkovo, Moscow Region) were used, including synthetic sex attractants. Pheromone traps were placed in orchards according to the standard procedure, randomized in triplicate. As a result of trapping moths in conditions of the Leningrad region, a low number (29-31 moths per season) in 2008-2009, an outbreak of mass reproduction (524 moths) in 2020 and moderate development of the pest under the influence of seasonal abiotic factors in 2021 (297 moths) were revealed. The cherrybark moth flight dynamics in those years has been studied in detail. It is assumed that due to the continuing trends of climatic anomalies, the likelihood of a recurrence of favorable weather conditions for the cherrybark moth outbreak in orchards of the Leningrad Region is increasing. Original research and analysis of the literature have found that the cherrybark moth began to occupy a prominent place in the complex of orchard pests under the conditions of the north-west of the Russian Federation.
