Date of creation:



1:20 000 000.

Accuracy of the map:

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


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:

Insect area was divided into a zone of low (inconsistent) damage with local pest distribution, where it infests up to 50% of host plant plantations; and a zone of high damage, where the pest infests up to 100% of such plantations every year.

Method of map production:

Hand drawn maps were scanned, georeferenced and vectorized. The borders of the insect area were determined according to results of the analysis of the following sources: Ivanova (1962), Shabliovskii & Gusev (1964), Shtundyuk (1968), Mikhailova (1970), Kaz.min (1977). Cartographical materials in listed and other publications are absent. Territories of zones of the beetle.s distribution and damage are shown provisionally, in accordance with Mikhailova.s article (1970), who notes that the Potato Ladybird lives predominantly in populous and intensively developed low-lying districts located along big rivers and railways.
