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 of 3 layers. Area and damage zones are shown by polygons.

Accuracy of the classifier:

Potential area of the Oriental Armyworm includes imago collecting sites during extensive migrations of moths with monsoon winds and air streams of a cyclonic origin (Berger, 1985; Makarova & Doronina, 1988, 1994; Pospelov, 1989). Two damage zones were defined within the moth area: 1) high damage (density of larvae is 10 and more individuals per 1 sq.m on the average at 50% and more areas invaded); 2) low damage (density of larvae is less than 10 individuals per 1 sq.m). The subdivision of zones was determined according to a rise in the phase of pest population dynamics after periods of depression when the species doesn.t show a high degree of harmfulness (Berger, 1985; Onisimova et al., 1987; Makarova & Doronina, 1988; Pospelov, 1989).

Procedure of map drawing:

Distribution and damage zones were drawn according to the analysis of map materials and literature data published (Onisimova et al., 1987; Pospelov, 1989; Makarova & Doronina, 1994; Sukhareva, 1999; Kononenko, 1988, 2003; Sharma & Sullivan, 2000). The pest damage zones were corrected according to the vector layer of I.E. Koroleva et al. characterising the arable lands distribution.
