The aim of the presented research was to determine how water extracts obtained from Medicago sativa herbage, Carum carvi fruits, Glycine max seeds, Phaseolus vulgaris pericarp and Morus alba leaves affect grain weevil (Sitophilus granarius L.) beetles. It was found that the plant water extracts tested demonstrated a varied effect on grain weevil beetles. The strongest repellent effect, in place throughout the observation period, was reported for soybean extract. A similar repellent activity yet increasing with time, was reported in the case of white mulberry extract. The weakest effect was recorded for alfalfa herbage extract.
