The stored grain pests feed on the grains both in the field and in storage, reducing the quality and the germination rate. The search for other control methods for these pests, such as the use of essential oils, may reduce the use of synthetic insecticides. Thus, the objective of this work was to evaluate the toxicological effect of the essential oils of Rosmarinus officinalis (Rosemary), Myrocarpus frondosus (Cabreúva), Citrus limonum (Lemon) and Mentha piperita (Peppermint) by fumigation on A. obtectus and S. zeamais. The results show that the essential oils showed toxicity on A. obtectus and S. zeamais. The essential oil of R. officinalis showed CL50 and CL90 of 3.77 μl / ml air and 6.49 μl / ml air respectively on A. obtectus. The oils of M. piperita, C. limonum and M. frondosus provided mortality between 65% and 4%. However, the same essential oils caused mortality in S. zeamais between 41% and 0%. The essential oils showed fumigant toxicity on two stored grain pests S. zeamais and A. obtectus.
