In the present investigation an attempt was made to determine the antibiosis of three salt stressed wheat varieties (Shafaq, Inqlab-91 and Sehar-2006) at three salinity levels (8, 12 and 16 dS m-1) to red flour beetle, Tribolium castaneum (Herbst). The grains of three varieties were ground and sieved through 80 mesh. Life history parameters, i.e., larval and pupal durations and survivals, adult emergence, fecundity and egg hatching was observed by introducing 10 pairs of pupae, from previously reared beetles, on three varieties at their respective salt levels. One control was included with grains of the plants, which were irrigated with distilled water only. Results have shown that varieties had significant difference among the treatments for larval duration, which was significantly extended in different varieties at various salt levels.
