Eight Egyptian floor wheat cultivars, Triticum aestivum L., were assessed to determine their appropriate level of resistance by Rhyzopertha dominica F.and Tribolium confusum Jacquelin du Val under lab conditions. Free choice test for attraction insect adults was used in the first experiment at time interval from 0.25 to 5 days post infestation. Comparing the attractions after 5 days, the data showed that the lowest attracted numbers of R. dominica adults was recorded 8.94 and the highest numbers was counted 15.61 at SAKL1, SIDS1 cultivars, respectively. The cultivars can be descending order with the attracted number of R. dominica as the following: SAKL8< DEBEIRA< BACANORA< SAKL1 <GIZA168< GIZA164< SIDS6< SIDS1.The descending order could be the similar for T. confusum. Statistically there are significant differences between the numbers the four cultivars that have the lowest attracted adults than the rest cultivars. In the second experiment to every cultivar two pair of test adult insect was reared on cultivar. The number of F1 and duration of offspring to every stage were determined. Based on the Dobie Index (D.I.) for R. dominica, SAKL8, DEBEIRA, BACANORA and SAKL1 were showed resistant cultivars. While the SIDS1 and SIDS6 cultivars have moderately resistant. For T. confusum all cultivars showed resistant except SAKL8 SIDS1. They showed moderately resistant. BACANORA cultivar was showed the lowest D.I. value in two tested insects. These results involve that storied grain managers should be a familiar with prospective differences in wheat susceptibility to R. dominica and T. confusum.
