Date of creation:

21.01.2004.

Scale:

1:20 000 000.

Accuracy of map:

Map was created based on materials of maps of natural scale 1: 33 000 000.

Projection:

"Alber.s Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Vector map. Area of species distribution is shown by polygons. Zones of recorded mass outbreak are shown by polygons.

Accuracy of classifier:

Within the area of distribution the harm zones and foci (centers) of outbreaks are distinguished. The classification into zones is made for the expansion phase of the Beet webworm population dynamics after depression periods when its harmfulness can be undetectable, and the pest maintains its large population numbers at natural stations.

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 (Koroljeva et al., 2003). Hand drawn maps were scanned, georeferenced and vectorized. The distribution area was determined according to Frolov & Kuznetsova (2003) and adjusted for Byelorussia, Ukraine, Moldova, Kazakhstan, Armenia, Azerbaijan and Middle Asia according to the following sources: Zverezomb-Zubovskii (1931), Ushinskii (1934), Lukyanovich (1934), Vashakidze (1976), Azaryan & Pustovarov (1977), Nikonov (1987), Tribel (1989) and label data from the collection of the Insect Collection of the Zoological Institute of the Russian Academy of Sciences (ZIN RAS, St. Petersburg, Russia). The borders for the harm zones and the foci of outbreaks were determined according to Frolov et al. (2000), Kuznetsova et al. (2001) and the data of the Russian Phytosanitary Centre (Moscow). These areas were adjusted in the regions of agricultural crops for the map reproduction outbreaks according to Zverezcomb-Zubovskii (1931).
