Date of creation:



1:20 000 000.

Accuracy of map:

Map was created based on a map of scale 1:40 000 000 and on the basis of information taken from literature and of the collections of the Zoological Institute, Russian Academy of Sciences.


.Alber.s Equal Conica 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 pest damage are shown by polygons.

Accuracy of classifier:

Within the area of distribution only a zone of low damage was established for the pest damaging fruit plants. In the zone of low damage not more than 10-15 adults occur on one fruit tree in the spring.

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 map of the distribution area was based on the collection of the Zoological Institute RAS. According to the following sources T. aequatus causes low harm to orchards in the Ukraine, Rostov Region, Stavropol' Territory and in the Caucasus: Arkhangel'skii (1928), Dobrovol'skii (1951), Vasil.ev (1955), Samedov (1963). Borders of the zone of low damage were adjusted to economically significant areas of fruit crops within the area of Tatianorhynchites aequatus.
