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

Basic contents:

Vector map is composed of 3 thematic layers. Zones of distribution and damage are shown by polygons.

Accuracy of the classifier:

The insect area is divided into zones of moderate and low damage using the published materials (Sokolova, 1901; Taranukha, 1952, 1954). The zone of moderate damage includes regions that are characterized by average population density 5 and more bugs per 1 sq. m; the zone of low damage has 1 to 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 been also taken into account. The results of the analysis of hosts spreading have been used according to the Atlas of the USSR vegetation, taking into account the temperature preference of this insect. The species is observed northward to Byelorussia, Smolensk, Moscow, Nizhnii Novgorod, Ryazan' Regions, Tatarstan. The bug does not appear in Siberia and Primorskii Territory (Puchkov, 1972). Authors include the Transcaucasia, Middle Asia, and Kazakhstan into the pest area, but this species occurs there in small number, in mountains only. High mountains and deserts are excluded from area. The borders of zones of different damage are given using criteria that have been published by N.N. Sokolova (1901); M.D. Taranukha (1952, 1954); I.M. Kerzhner & T.L. Yachevskii (1964); V.P. Vasil'ev (1973); A.A. Migulin (1983). The insect has low fecundity, observing late awakening, so it is not very dangerous. It usually feeds on grasses. Sometimes, during droughty years, the pest appears on crops. Moderate damage appears usually in southern part of forest zone and in forest-steppe zone (Puchkov, 1972; Vasil'ev,1973). The vector map of the distribution of cereals within the territory of the Former Soviet Union have been used for the correction of damage zones (Koroleva et al., 2003). The map has been scanned; its registration and vectorization have been made by GIS-technology means.
