Abstract: The varieties of wheat screened for resistance against Tribolium castaneum revealed that none of the variety was immune. The maximum developmental period of this insect (30.83 days each) was recorded in Raj-4083 and Raj-1482. The minimum developmental period (29.67 days) was observed in Raj-4120. The minimum adults (68.83) were emerged from variety Raj-1482 followed by Raj-4083 (155.50), Raj-3765 (163.17) and Raj-3077 (175.67). Maximum number of adults (223.00) emerged from Raj-4120 followed by Raj-1972 (219.33), Raj-3777 (218.33) and Raj-1555 (216.83). The maximum weight loss (5.53%) was recorded in Raj-4120, whereas, minimum (1.27%) in Raj-1482. The varieties Raj-1972, Raj-1555, Raj-3777, Raj-4037, Raj-6560, Raj-3077, Raj-3765 and Raj-4083 stood in the middle order to reveal the weight loss caused by T. castaneum. The maximum growth index (18.22) was obtained in variety, Raj-4120 followed by Raj-1972 (17.97) and Raj-3777 (17.95). The minimum growth index was obtained in Raj-1482 (13.73) followed by Raj-4083 (16.37). The growth index in other varieties was found in the middle order.
