Basic content:

Vector map consists of 4 layers and legend. Area and zones of harmfulness are shown by polygons.

Accuracy of the classifier:

Geographic area is divided into zones of strong, moderate and weak harmfulness, based on periodicity of mass outbreaks and increases in population density. The zone of strong harm is characterized by outbreaks every 2nd-3rd year. The zone of moderate harm is characterized by outbreaks very 5th year, and in the zone of weak harm, outbreaks are observed very 8th year or greater (All-Russia Institute of Plant Protection, 1985).

Method of map production:

Scientists were given maps with boundaries of Oblasts and arable lands. After reviewing historic literature, species distribution was hand drawn on maps. If data were on the Oblast-level, distribution is on the Oblast level. In some cases, Oblast.s are further refined by boundaries of the Arable Land Map. Hand drawn maps were scanned, georeferenced and vectorized (Sokolov & Bashenina, 1994).
