Map was created based on materials of maps of natural scale 1:12 000 000.Projection:

Vector map. Area of species distribution is shown by polygons. Zones of recorded mass outbreak are shown by polygons.Accuracy of classifier:
Depending on economic significance, the area was divided into zones of strong (stable) and moderate (unstable) harmfulness. Periodicity of rising pest populations and mass outbreaks was used to determine the boundary of each zone. In the zone of strong (stable) harm, rising populations and mass outbreaks were registered at least every 2nd-3rd year and in the zone of moderate (unstable) harm, approximately every 5th year.Method of map production:
Scientists were given maps with boundaries of Oblasts and arable lands. After reviewing historic literature, species distribution was hand drawn on maps. If data were on the Oblast-level, distribution is on the Oblast level. In some cases, Oblast.s are further refined by boundaries of the Arable Land Map (Koroljeva et al., 2003). Hand drawn maps were scanned, georeferenced and vectorized. Zones of harmfulness were determined according to the methodical guidelines of the All Russian Institute of Plant Protection (1985).Reference citations:
