The aim of the study was to determine the impact of accompanying plants: sweet alyssum (Lobularia maritima L.) and white mustard (Synapis alba L.), on the incidence of pests of the broad bean (Vicia faba L.) variety Bartek, in the intercropping system. The observations of the number of the beetles of Bruchus rufimanus Boh. and Sitona spp were made. The broad bean was grown along with two other plants in varying spacing (the distances between rows were 50, 65 and 80 cm) and in homogeneous cultivation (the distances between rows were 50 cm). Broad bean in a homogeneous cultivation served as a control. In addition, the broad bean from homogeneous cultivation subjected to a standard protection by chemical insecticides was also analyzed. The measurements were carried out in field conditions, by using an entomological bucket, through the shedding of insects from randomly selected 30 plants per plot. The sweet alyssum as an accompanying plant showed no significant influence on the occurrence of herbivorous beetles of Bruchus rufimanus Boh. and Sitona spp., regardless of the spacing between the rows. The white mustard as a companion plant showed a significant impact on increasing the number of Bruchus rufimanus Boh. beetles in the middle row spacing (65 cm). The impact of white mustard on other beetles has not been detected.
