The effect of contamination of birch (Betula pendula Roth) leaves with heavy metals on the feeding of imagoes of the willow leaf beetle (Lochmaea capreae L.) was studied under laboratory conditions. The imagoes preferred feeding on leaves less contaminated by Cd, Mn and Zn. The Pb content was tolerated on all the studied levels. The repellent effect of Zn 8,000 μg/ml in the Pb + Zn regime was compensated by Pb 500 μg/ml; the effect of Cd 250 μg/ml in relation to Mn 10,000 μg/ml was similar.
