1:20 000 000.Accuracy of the map:
It is based on materials of the map with scale 1:33 000 000, using the information taken from literature.Projection:
"Alber's Equal Conica for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic content:
Vector map, which consists of two thematic layers. Area and zone of damage are shown by polygons.Accuracy of the classifier:
Within the distribution area, the zone of low damage has been allocated where the insect density reaches 1-2 and more individuals per sq.m in favorable habitats (banks of reservoirs, hotbeds, vegetable gardens, etc.)Method for map production:
A map of the African Mole Cricket distribution is drawn on the basis of published data (Gerasimov & Osnitskaya, 1961; Shchegolev, 1964; Mishchenko, 1972; Storozhenko, 1986). In the former USSR territory, the pest area spreads from the Caspian Sea to Kunashir Island, excluding territory from Kazakhstan-Russian border to Amur Region, as well as mountain territories and deserts. The northern border of area runs across the line Kazan . Chelyabinsk (Shchegolev, 1964), then Amur Region . Island of Sakhalin (Storozhenko, 1986); western border is from Caspian Sea to Samara, Kazan; southern border passes along southern frontiers of Turkmenistan, Tajikistan and Kyrgyzstan; in east part of the area, the southern border runs along Russian-Chinese frontiers in Amur Region and Primorskii Territory (Storozhenko, 1986). Zone of low damage coincides with the arable land distribution (Koroleva et al., 2003) in the area limit of G. africana.Reference citations:
