Abstract
In arable lands (sod-podzolic soils) of the Smolensk region, wirewprm larvae concentrate in the 0-10 cm soil layer in early spring and move downwards to the 20-cm depth in June-July. Under drier conditions in August they may reach down to 40 cm, but most remain between 15-20 cm layer. In September-October, with the beginning of the autumn rains and the intensive feeding season, they move back to the upper layers. Wintering takes place at the 10-45 cm depth.
