.Alber.s Equal Conica for the USSR., 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic content:

Vector map, which consists of 2 thematic layers. Area of distribution and zone of damage are shown by polygons.

Accuracy of the classifier:

Within the area of distribution, the zone of low damage is established according to the extent of damage to alfalfa. In the zone of low damage, harmfulness of S. humeralis is about 1 score point under the 5 score-points of harmfulness scale (Kopaneva et al., 1983). Threshold of harmfulness on the alfalfa crops in phase of sprouts and re-growth is 5-10 adults per sq. m.

Method of map production:

Data from the open publications are used for allocation of area and zone of pest damage. Map of the area is based also on the analysis of the collection of the Zoological Institute RAS. The localities of the species are marked in coordinate system on blank geographical map by standard means of GIS-technologies. In the former USSR, the area includes the European part northward to Leningrad Region (Silfverberg, 1992; Ioannisiani, 1972; Isaev, 1994), whole Caucasus (Arzanov, 1989; Ismailova, 1993), South of Western Siberia (Opanasenko, 1986), Middle Asia, Kazakhstan (Alimdzhanov, 1951; Baitenov, 1974; 1975). The zone of low damage comprises territory of the alfalfa-growing in the south of the European part of the former USSR, southward of forest-steppe zone, in the Caucasus, and in Tadjikistan, Uzbekistan, Kyrgyzstan with adjacent regions of Kazakhstan (Pavlovskii & Shtakelberg, 1949; Alimdzhanov, 1951; Petrukha, 1969; Kopaneva et al., 1983; Isaev, 1994).
