Date of creation:

Scale:

1:20 000 000.

Accuracy of map:

It is created on materials of map of natural scale 1:33 000 000.

Projection:

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

Basic contents:

Vector map is composed of 2 thematic layers. Zones of distribution and damage are shown by polygons.

Accuracy of the classifier:

The insect area is divided into the zone of low damage using the published materials. The zone of low damage includes regions that are characterized by periodical number of larvae in ground (depth of up to 10 cm). no more than 80 on 1 square meter during early spring period (Shuster, Krisachenko, 1980).

Method of map production:

The area and damage zone of Contarinia pisi Winnetz. have been marked on a blank map by results of the analysis of the published materials. The northern border has been marked also after the published materials (Mamaev, 1964; Vasil'ev, 1973). Within the territory of the Former USSR the species is observed in Ukraine, Byelorussia, Baltic States, European part of Russia. Its harmful activity is reported in central, western, northern part of Ukraine, in Central Black Earth zone (Rakauskas,1962; Karavyanskii,Mazur,1975). The harmfulness is characterized as low. The vector map of distribution of pea within the territory of the Former USSR have been also used for the correction of damage zones (Koroleva et al., 2003). The map has been scanned; its registration and vectorization have been made by GIS-technology means.
