    Investigations have shown that storage bugs seriously harm grains during storage. In the interim, essential oils (EOs) have been proven to be a good botanical pesticide. The anti- properties of essential oil, which was obtained by steam distillation, were evaluated using -limonene, carvone, and their two optical isomer components using contact, repelling, and fumigation techniques. Simultaneously, the fumigation, contact, and repellent activities of carvone and its two optical isomers mixed with -limonene against were evaluated. The results showed that its main components ( -carvone, -limonene), and -carvone exhibited both fumigations (LC = 14.47, 4.42, 20.9 and 3.78 mg/L) and contact (LD = 7.31, 4.03, 28.62 and 5.63 µg/adult) activity against A binary mixture (1:1) of -carvone and -limonene displayed an obvious synergistic effect. A binary mixture (1:1) of carvone and its two optical isomers exhibited an obvious synergistic effect, too. Furthermore, the repellent activity of the EO, carvone, and its two optical isomers, -limonene, and a combination of them varied. To stop insect damage during storage, and its components can be utilized as bio-insecticides.
