Introduction: Laboratory research to control Sitophilus oryzae L., Rhyzopertha dominica F., Cryptolestes ferrugineus L. and Tribolium castaneum Herbst. by cineole essential oil aimed to find out potential source of new fumigants. Methods: Three experiments with cineole were done: first, to test efficacy of cineole against different developmental stages of insects ; second, to test effective concentration of 50, 100, 150, 200, 250 μ l/L ; and third, to test effective cineole concentration in spaces differently occupied with wheat (empty space, 50% and 95% filled up). Results: Developmental stages of C. ferrugineus in wheat grain were more sensitive to cineole in comparison to the remaining tested species. By testing 5 concentrations of cineole, 100% mortality of C. ferrugineus was obtained with 50 μ l/L. However, 100% mortality of R. dominica was obtained with concentration of 150 μ l/L, with S. oryzae and T. castaneum at concentration of 250 μ l/L.Concentration of cineole of 50μ l/L in empty space induced nearly 100% mortality in all four tested insect species, while results of fumigation of space occupied with wheat (50% and 95%) did not prove to be successful and acceptable. Conclusion: Cineole proved to have fumigant effect in vitro, but it would be needed to apply high concentrations relative to phosphine or methyl bromide to gain satisfactory results.
