Abstract
Laboratory studies were conducted to evaluate the susceptibility rates of seven date varieties (Aamry, Frihi, Partarnoda, Kakaa, Malakaby and Sakkoti) to infestation by Ephestia cautella (WLK.) and Ephestia calidella (Guen.). Therefore, susceptibility index "SI" was determined by recording some biological parameters including fecundity, mean developmental period and food consumption. The obtained results could be categorized into three main groups. The first includes El-Aamry variety which has high SI values of 3.74 and 3.72 for both Ephestia cautella and Ecalidella, respectively. Such tested insects consumed more quantities from this variety and in turn gave more progeny with short developmental periods. The second comprises both, Frihi, Partamouda, Kakaa and Malakaby varieties which have the lowest SI values ranging from 1.93 to 2.44 for both examined insects. These insects consumed lower quantities from both date varieties and consequently produced fewer progeny with longer growth durations. The third group includes Saidi and Sakkoti varieties the rest date varieties which have intermediate SI values. Finally, it is clear that there is no completely immune variety and we need other complementary approaches for protecting stored dates
