The trapping of weevils on cutting areas using different soil preparation methods was tested. A soil cutter mixing mineral soil with humus best stimulated the weevil trapping. The methods connected with breaking up the humus layer: manual disk ploughing or using an active plough and ploughing with deep furrowing (strips) stimulated weevil trapping to the smallest degree. The piles of branches on the felled areas had no effect on the increase of weevil trapping, while the winter felling, unlike the summer one, increased the trapping level. On the basis of the results obtained in the study the specified methods to improve the cutting management were proposed.
