Attractiveness of broad bean for Sitona spp. in conditions of soil pollution with heavy metals mixtures

摘要

The aim of the work was to compare the effect of soil pollution with single heavy metals (Cd, Cu, Pb, Ni, Zn) and its mixtures with zinc and nickel on attractiveness of broad bean for Sitona beetles. Soil contamination with mixture of zinc with nickeland mixtures of these metals with cadmium, copper or lead on III level of soils pollution by these metals according to the Institute of Soil Science and Plant Cultivation classification led to a significant decline in attractiveness of broad bean for Sitona beetles. Inhibition of feeding in case of mixture of zinc with nickel was much stronger than when this metals were used separately. Mixture of zinc with nickel and periodically also zinc with lead, zinc with cadmium and nickel with copper on II level of pollution according to the Instytut Uprawy Nawozenia i Gleboznawstwa classification may reduce feeding of Sitona spp.
