Abstract
The common vole (Microtus arvalis Pall.) is a dangerous pest of fruit trees in Poland.
During a big infestation and in good conditions (thick snow cover) it can destroy even 100% trees in the young apple or cherry orchard.
It is estimated that mechanical soil cultivation and using herbicides reduces the number of rodents from Microtidae family in 60–90%. Cutting high weeds once per season reduces the number of common vole several times (Byers & Young, 1978; Wieland, 1994). As in the IPM orchards sowing herbaceous plants between trees is recommended to maximise biological control, a series of observations was carried out researching the effect of these plants on occurance of rodents.
