Authors:

Specialist-biologist - M.N. Berim, GIS-specialist - M.I. Saulich.

Date of creation:

2.12.2003.

Scale:

1:20 000 000.

Accuracy of map:

Map was created based on materials of map of natural scale 1:40 000 000.

Projection:

"Alber's Equal Area Conic", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Vector map. Area of species distribution is shown by polygons. Zones of pest damage are shown by polygons.

Accuracy of classifier:

The insect area is divided into zones of strong and low (weak) harm.
The zones with strong harmfulness are the regions that are characterized by periodical mass reproductions of the pest according to balls 5, 7, and 9, and the zones of low harmfulness, according to balls 1 and 3.

Method of map production:

Scientists were given maps with boundaries of Oblasts and arable lands. After reviewing historic literature and VIZR expedition data, species distribution was hand drawn on maps. The borders of the zones of harmfulness were drawn according to the following sources: Radchenko (1991), Berim & Radchenko (2002). 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 northern border was determined according to published materials (Shaposhnikov, 1964; Ivanovskaya, 1977), by the analysis of the spreading of the first and second hosts according to the atlas of the USSR vegetation and by the temperature preference of this insect. The distribution of wheat, barley, rye, millet, and oats within the territory of the Former Soviet Union has also been considered.
