Abstract

The relevance of the study is determined by the need to improve the monitoring of agricutural crop pest distribution. The aim of the research is to identify zones of different phytosanitary risks within the area of crop cultivation in Russia and neighboring countries. Maps characterizing the distribution and harmfulness zones of phytophagous species were used as the primary material for integrated computer analysis. It was necessary to adjust and update a number of maps taking into account research data published over the last 10 years. The analysis resulted in the creation of maps characterizing phytosanitary risk zones for the cultivation of fruit and grain crops by a corresponding complex of specialized phytophagous insects, as well as of agricultural crops in general by a complex of polyphagous pests. Three zones of phytosanitary risk have been outlined, as a consequence of the total harmfulness of phytophagous complex. The combined geoinformation system for agricultural crop pests is included in the “Phytosanitary Risks” cartographical database, which is a set of vector files for all major phytophagous species, distribution and harmfulness zone layers for these species. Outlined zones with low, medium and high phytosanitary risks can be used in the development of integrated pest management.
