A study of the influence of intercropping broad bean with phacelia on the occurrence of weevils and broad bean beetles was conducted in the years 2006-2009. The harmfulness of Sitona spp. beetles feeding on the leaves (the number of U-shape notches and the number of damaged leaves) and the harmfulness of the larvae, as well as the feeding on the broad bean root nodules was taken into account. The harmfulness of the broad bean beetle was determined by assessing the condition of the seeds. The influence of phacelia on the presence of weevils (Sitona) and broad bean beetles (Bruchus rufimanus) as broad bean pests was not observed. A smaller amount of broad bean seeds damaged by the broad bean beetle was determined only in some of the years of the study in the plots in which the phacelia was intercropped with broad bean.
