The aim of study is the effect of trophic medium of twelve soft wheat varieties on the biotic potential of S.granarius L. After 3 months of storage under laboratory conditions at 27 ± 2 ° C and 70 ± 5% rh, have reveals that the preferred varieties for development of this species are Hidhab, Mahon Demias, Arfort and Siete Ceros. This latest was found to be the most susceptible. Growth index and loss were highest with 2.08 and 3.27% respectively. Laboratory analysis of the main grain components of the different varieties suggested that the susceptibility of these varieties to S. granarius infestation may be attributed to the high content of protein and low content of carbohydrate compared to resistance varieties.
