Quinoa, Chenopodium quinoa Willd. (Chenopodiaceae) is a herbaceous flowering plant which is originated in the Andeas region (Latin America). Seeds of quinoa are of high nutritional value, so it is important for the diversification of future agricultural systems. It is believed that quinoa deserves more research for successful cultivation in order to get the benefit of its high nutritional value. The presented study dealt with a survey and study on the common insect species which proved to infest quinoa seeds during storage.
             Quinoa seeds storage proved liable for infestation by three insect species; Ephestia kuehniella (Zeller), Lasioderma serricorne and Tribolium castaneum. (3.17±0.08, 21.50±1.23, 36.25±0.63 and 44.00±0.25 total infestation % at the end of each of the 4 successive years, respectively). By close observation, E. kuehniella proved to be the most common and serious pest on quinoa seeds. This insect species caused the first infestation, followed by L. serricorne and T. castaneum. The results of this study suggest that E. kuehniella more tolerant to quinoa saponin. Some biological information on the surveyed insect species was carried out. The role of saponin against either stored grain insect pests needs more investigation
