Map was created based on materials of maps of natural scale 1: 33 000 000.Projection:

Vector map. Area of species distribution is shown by polygons. Zones of recorded mass outbreak are shown by polygons.Accuracy of classifier:
Two damage zones were defined within the moth area. In the high pest damage zone the number of larvae permanently exceeds the economic threshold of 0.5-2 larvae per sq. m as follows: in the northern regions on winter cereals, vegetables and potato; in the Ukraine and Central-Chernozem regions of Russia on sugar-beet, maize, tomatoes; in Transcaucasia and Middle Asia on cotton. In the low pest damage zone the number of larvae reaches the economic threshold not more than 2 times during a decade. This subdivision of the damage zones is based on the number of 1st generation larvae causing maximum losses of yield to agricultural plants.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. The following literature and map materials were used to determine the pest distribution and damage zones: Shchegolev et al. (1934), Nikitin (1936), D'yakonov & Kozhanchikov (1949), Druzhelyubova (1975), Zakharenko et al. (1985), Sukhareva (1999), Kononenko (2003). The map of Druzhelyubova (1975) was used as a base map to determine the borders of the damage zones.Reference citations:
