Hosts. Oryzaephilus surinamensis (Sawtoothed grain beetle) is a cosmopolitan species which damages several stored products. On rice, flour and other cereals and their products, date-palm, nuts, seeds, sugar, candy, tobacco, almond, dried meat, dried apricot, dried fig and other dried fruits, in granary ( Farahbakhsh 1961; Modarres Awal 1997; Bagheri-Zenouz 2010), wheat, corn, barley, wheat flour, bran, pasta, bread, oil seeds, dried herbs, and natural history collections ( Bagheri-Zenouz 2010; Zarei et al. 2015). Additionally this pest causes damage not only by feeding but also with its feces-contamination, severely reducing the quality of the infested commodity ( Mollaie et al. 2011).
