Control ways in stored-product soils mainly rely on alternative pesticides. The modification of new environmentally friendly alternatives, such as essential oils (EOs), is a key issue. The aim of the current study was to develop three commercialized essential oils that were examined for fumigant and contact acts against adults of the saw toothed grain beetle, Oryzaephilus surinamensis )L.( (Coleoptera: Silvanidae). In general, the results of this study showed that with increasing concentration and duration of exposure, toxicity activity increased and weight loss decreased. In case of fumigant tests, orange oil outperformed anise oil in terms of effectiveness against O. surinamensis adults. While, anise oil showed a higher toxicity level of contact compared to the other two oils, particularly against adult O. surinamensis. The results of this study suggest that these essential oils can be used as viable alternatives to pesticides against O. surinamensis in stored grains and stored materials.
