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:

Threshold of harmfulness of Tychius medicaginis in bud formation period of alfalfa is 5-8 adults per 1 sq. m. 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, T. medicaginis harmfulness is not more than 2 points under the 5-point scale of harmfulness (Polyakov et al., 1983).

Method of map production:

Data from the open publications are used for allocation of area and zone of pest damage. In the former USSR, the area of T. medicaginis includes Latvia (Silfverberg, 1992), Belarus (Ioannisiani, 1972), Moldova (Poiras, 1998), Ukraine (Kolobova, 1929; Petrukha & Globova, 1974), the European part of Russia (Ponomarenko, 1940; Korotyaev, 1983; Isaev, 1994; Dmitrieva, 2005), the South of West Siberia (Legalov, 1994; Legalov & Opanasenko, 2000), the Caucasus (Arzanov, 1989; Ismailova, 1993), Middle Asia (Arnol'di, 1949; Ioannisiani, 1972; Nasreddinov, 1975) and Kazakhstan (Serkova, 1961; Baitenov, 1974; Caldara, 1990). The zone of low damage comprises territory of alfalfa-growing in the steppe zone (Serkova, 1961; Polyakov et. al., 1983).
