Sitotroga cereaterki (Olivier) is a world wide primer pest of stored grains owing to its high mobility, ability to colonize intact grains as well as infest grains both before and after harvest. The present study aimed to evalute the susceptibility of 13 wheat varieties to attack by this pest. Screening was based on comparing values of susceptibility index (SI), weight loss(%), germination (%)of the tested grain varieties. Also, a correlation were made between SI and the mean grain weight and germination. The obtained results could be categorized into three main groups: the first indude the highly susceptible varieties, since it has significant high values of SI as Sedesland Giza164 (6.43 and 6.19, respect). These high values are supported by high values in the progeny with a shorter growth duration. The r^d are representing the least susceptible varieties, which in contrast, has the lowest values of SI and characterized by fewer progeny number with longer growth period. These include BeniSwaifl, Giza168, BeniSwaif3. The 3'^d group induded rest of the tested varieties, have intermediate SI values and their related parameters. Correlation among grain size and values of SI was non-significant indicating that no relatioship between them, while a significant correlation between SI and gemilnation(%). It is dear that from the obtained findings that there is no completely immune variety, and accordingly application of other safe complementary approches to rotect our wheat produced earl should be cosidred.
