The saw-toothed grain beetle, Oryzaephilus surinamensis (L.) is considered one of the most serious insect pests which attack different stored products in all over the world. This study was carried out in the Laboratory of Plant Protection Department, Faculty of Agriculture, Zagazig University, Egypt to study the susceptibility of six dry date, Phoenix dactylifera (L.) varieties (Malkabi, Skooty, Pertomoda, Shamia, Dekina and Gondella) to infestation with the saw-toothed grain beetle under non-choice and free-choice conditions. Parameters of evaluation among the tested varieties as regards resistance were mean complete developmental period, number of F1 emerged adults, susceptibility index and weight loss % after one and three months of storage. Results showed that the shortest mean complete developmental period of the insect was 28.33 days on Skooty variety, while the longest one was 33.67 days on Gondella variety in free–choice bioassay method. Dekina variety was the most preferred variety to the insect since their fruits produced the highest mean insect number of progeny (73.67 adults), whereas Skooty variety recorded the lowest mean (25.67 adults). Values of susceptibility index (SI) ranged between 4.38% for Gondella and 10.69% for Skooty.
