"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 high and low damage after the published materials. The zone of high damage includes regions that are characterized by periodical damage of haricot-bean grain reaching 70-90% in natural conditions (decrease of germinating power is 70-80%); the zone of low damage is characterized by damage of grain reaching 40% (decrease of germinating power is 35%).

Method of map production:

The area and damage zones of A.obtectus Say. have been marked on a blank map by results of the analysis of the published materials. The northern border has been marked after the published materials (Medvedeva, 1953; Vasil'ev, 1973; Pavlyushin, Lazarev, 2005 et al.). The northern part of the species area includes Lithuania, Byelorussia; Ryazan, Kaluga, and Tula Regions, Tatarstan, Bashkortostan. The insect migration to the North is limited by temperatures. The Bean Weevil prefers the temperatures about 27-29°C and high humidity, so there are not high numbers in Middle Asia and in most part of steppe territory. It is very sensitive to temperatures below zero. Sometimes it is marked in southern part of Siberia. In storehouse conditions, the pest is observed in more northern regions. The borders of zones of different harmfulness are given, using criteria that have been published by N.G.Sindyashkina (1958); M.I.Shevchenko (1970); E.V.Rachvelishvili (1975); A.P.Karapetyan (1983). High damage is reported in Transcaucasia, Krasnodar Territory, and in the southern regions of Ukraine where the insect can winter in natural conditions (Chelidze, 1966; Ragimov, 1973; Rachvelishvili, 1975; Karapetyan, 1983 and others). The Bean Weevil also damages plants in Stavropol' Territory, Rostov Region, and in some regions of Ukraine (Sindyashkina, 1958; Vasil'ev, 1973). The species has spotted distribution, having been a quarantine species for a long time. The vector map of distribution of haricot-bean within the territory of the Former Soviet Union has been also used for the correction of damage zones (Terekhina, 2004), as well as the map of arable lands (Koroleva et al., 2003).
