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

Basic contents:

Vector map is composed of 4 thematic layers. Polygons and points show the zone of distribution and the pest damage zones.

Accuracy of the classifier:

The insect area is divided into zones of high and low damage using the published materials (Nevskii, 1929; Vasil'ev, 1973; Sumarokov, 1978 and others). The zone of high damage includes regions that are characterized by periodical damage to plants according to points 3-5; the zone of low damage is characterized by periodical damage according to points 1 and 2 (Drakhovskaya, 1962).

Method of map production:

The area and damage zones of R. maidis Fitch have been marked on a blank map by results of the analysis of the published materials. The materials of VIZR expeditions have been also used. The northern border has been marked after the published materials (Shaposhnikov, 1964, 1972; Ivanovskaya, 1976), the materials from suction traps; the results of the analysis of host spreading (cereals, maize) have been used according to the Atlas of the USSR vegetation, taking into account the temperature preference of this insect. This border coincides with southern borders of Smolensk, Tula, Kaluga and Ryazan' Regions, republics of Tatarstan and Mordovia. However, this species is marked in more northern regions including the Leningrad Region (observations of VIZR collaborators). Aphid is observed also in East, South, and North Kazakhstan (Nevskii, 1929); individual insects are marked in West Siberian steppe and mountain-steppe zones (Ivanovskaya, 1976). High mountains and deserts are excluded from the area. The borders of zones of different harmfulness are given, using criteria that have been published by V.P. Nevskii (1929), G.Kh. Shaposhnikov (1972), V.P. Vasil'ev (1973), A.M. Sumarokov (1978), and others. The northern border of low damage zone coincides with the northern border of forest-steppe zone of southern part of Russia, Ukraine, and Moldova. Low damage is observed in Middle Asia, East and South Kazakhstan. High damage is marked in steppe zone of Ukraine, in Transcaucasia, North Caucasus. The vector map of distribution of cereals and maize within the territory of the Former Soviet Union has been also used for the correction of damage zones (Koroleva et al., 2003).
