Reference citations: D.yakonov A.M., Kozhanchikov I.V. A correction to the pest damage zones was made based on large region distribution according to the map of arable lands (Koroleva et al., 2003). The species also does not live in sandy and clay deserts. The zones of high mountain areas of the Caucasus and the Central Asia were excluded from the area. The damage and distribution zones were drawn according to the analysis of the following map materials and literature data: Shchegolev et al.

Hand drawn maps were scanned, georeferenced and vectorized. In some cases, Oblast.s are further refined by boundaries of the Arable Land Map (Koroljeva et al., 2003). If data were on the Oblast-level, distribution is on the Oblast level. After reviewing historic literature, species distribution was hand drawn on maps. Method of map production: Scientists were given maps with boundaries of Oblasts and arable lands. This subdivision into damage zones is based on the number of 1st generation larvae that cause the maximum loss of yield among agricultural plantings. m permanently or pest is absent among agricultural crops). m an area of low damage (number of larvae is less than 3 individuals per 1 sq. m) an area of moderate damage (number of larvae periodically reaches the economic threshold of 3-5 larvae per 1 sq. Accuracy of classifier: Three damage zones were defined within the moth area as follows: an area of high damage (number of larvae is permanently within the limits of 3-5 larvae or more per 1 sq. Zones of recorded mass outbreak are shown by polygons.

Area of species distribution is shown by polygons. Accuracy of map: Map was created based on materials of maps of natural scale 1: 33 000 000. Object description Download GIS-layers Authors: Object biologists - M.A. Pests Area of distribution and damage of the Black Cutworm (Agrotis ipsilon
