The experiment comprised of eight wheat varieties under laboratory condition. The recording of observations was started on 7th April, 2016 and lasted until to 11th August, 2016. The fortnightly population of the red flour beetle Tribolium castaneum (Coleoptera: Tenebrionidae) fluctuated significantly (P<0.05) and the results indicated that at first observation (07-04-2016), the red flour beetle population was (15.00±1.73), in variety ‘Sindhu’, gradually increased and reaching its peak population (51.66±1.20), on the last observation (11-08-2016). The interaction of variety × observation date examined that the red flour beetle were highest (51.66±1.20) in variety Sindhu when observed on 11th August; while lowest (3.33±0.88) in variety TD-1 on 7th March. Further the minimum populations of red flour beetle (8.59±1.17 and 8.53±1.05) were equally recorded for varieties Sarsabz and Hammal at minimum-maximum temperature (20.60-38.35oC) and relative humidity (40.70%). The ANOVA shows that there was significant (P<0.05) difference in population of red flour beetle between wheat varieties in all observational dates. Average maximum weight loss (96%) while the optimum was examined (85.61%). There was a positive and significant correlation in the red flour beetle population with mini-maximum and relative humidity, there is also a linear association of red flour beetles with the temperature and relative humidity.
