Twelve wheat varieties/lines (85054, 86175, Shalimar-88, 85205, 86371, 85276-2, 84021, 86299, Punjab-85, 83035, 86369 and 84133-6) were tested against khapra beetle and lesser grain borer in the laboratory. Significant differences existed among the varieties for number of bored grain and grain weight loss caused by T. granarium and R. dominica. A wheat variety, 86175 proved less susceptible to the pests. R. dominica gave minimum damaged grains (0.60%) and loss in weight (0.34%). In case of T. granarium, a variety 86299 was relatively more resistant. It gave minimum loss in weight (0.58%). Variety 86731 was comparatively less susceptible on the basis of damaged grains (1.10%)
