Date of creation:

12.09.2006.

Scale:

1:20 000 000.

Accuracy of map:

It is created on materials of map of natural scale 1:33 000 000.

Projection:

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

Basic contents:

Vector map is composed of 2 thematic layers. Zones of distribution and damage are shown by polygons.

Accuracy of the classifier:

After the published materials (Pavlov, 1954; Puchkov, 1972; Vasil'ev, 1973), the zone of low damage only is distinguished within the area, which is characterized by average population density 1-5 bugs per 1 sq.m.

Method of map production:

The northern border has been marked after the published materials (Kosov & Polyakov, 1958), the materials of VIZR expeditions have also been taken into account. The results of the analysis of host vegetation spreading have been used according to the Atlas of the USSR, taking into account the temperature preference of this insect. The species is observed northward to Byelorussia, Kursk, Tambov, Penza Regions. There are no materials about this insect distribution in Siberia and Primorskii Territory. In steppe zone and in Southeast of the European part, the bug occurs seldom (Puchkov, 1972; Vasil'ev, 1973). The pest is observed in Kazakhstan (Nurmuratov, 1986); it is presumed that it inhabits the mountains of Middle Asia in a small number. High mountains and deserts are excluded from area. The insect has low fecundity, its awakening is observed late, therefore, the object is not very dangerous. It usually feeds on grasses. Sometimes during droughty years, the pest appears in crops. Damage appears usually in southern part of forest zone and in forest-steppe zone (Puchkov, 1972; Vasil'ev, 1973). The zone of low damage is only distinguished; its borders are given using criteria that have been published by M.D. Taranukha (1952, 1954); A.N.Pavlov (1954); I.M. Kerzhner & T.L. Yachevskii (1964); M.N.Pogorelov (1965); V.P. Vasil'ev (1973); A.A. Migulin (1983). The vector map of the distribution of cereals within the territory of the Former Soviet Union has been also used for the correction of damage zone (Koroleva et al., 2003). The map has been scanned; its registration and vectorization have been made by GIS-technology means.
