Accuracy of map:

Map was created using maps of scale 1:33,000,000 and information from published literature and an analysis of the collections of the Zoological Institute and the Russian Academy of Sciences.

Basic content:

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

Accuracy of classifier:

Within the area of distribution, only a zone of low damage was established in accordance with the extent of damage to orchards. In the zone of low damage, less than 8-10 adults per tree occur at the end of spring and in the beginning of summer.

Mapping procedure:

Data from state publications were used to map the pest distribution area and the zone of pest damage. The map of the distribution area was determined following an analysis of the collection at the Zoological Institute RAS. The localities of the species were marked in a coordinate system on blank geographical map using standard GIS technologies. The borders of the zone of low damage were determined using Ter-Minasyan (1950), Dobrovol'skii (1951), Avet'yan (1952), Vasiliev (1955), and Samedov (1963). The zone of low harm is comprised of the territory of pear and apple growing in Ukraine, excluding the territories of Poles'e; the Moldavia, Rostov, and Stavropol regions; the Caucasus; the Samarkand region of Uzbekistan; and adjacent regions of Uzbekistan and Tajikistan.
