The effect of the powdered plants – lavender flowers Lavandula officinalis L and caraway fruits Carum carvi L on the migrating activity of the lesser grain borer Rhyzopertha dominica (Fabricius 1792) was investigated. The experiments were conducted in the laboratory in the temperature of 28°C, 60± 5% RH. In the conditions enabling migration of adult individuals of R dominica, addition to wheat grains lavender or caraway containing essential oils caused high emigration of the pests from the substrate with these plants added. Both the plants have a repelling effect on R dominica, especially in the initial period of infesting the substrate. It was then that a particularly strong repelling effect of lavender was observed: during the 100 days of the experiments emigration was 90–100 %. Application of caraway in the first 70 days of the experiments resulted in 80–95 % emigration. Moreover, lavender causes higher mortality of insects.
