The aim of this study was to investigate the effect of powdered plants: Salvia officinalis L., Artemisia absinthium L., Mentha piperita L., Allium sativum L. and Pimenta dioica L. on the mortality and development of the progeny of Rhyzopertha dominica F. Powdered plants were used at the following weight concentrations: 1.23%, 3.61%, and 5.88%. Experiments were conducted in a laboratory at 28°C and RH 60±5%. It has been found that the effect of the tested plants depends on their concentration. Among the five species of powdered plants: S. officinalis, A. absinthium, M. piperita, A. sativum, and P. dioica, the highest mortality in R. dominica was caused by P. dioica at all tested concentrations and as early as after the first day of experiments. Of the tested plants, the one that may find application in the protection of stored products from R. dominica is P. dioica, which has shown insecticidal activity against this insect species
