Abstract
This study aims to explore the susceptibility of wheat varieties in storage against Rhyzopertha dominica (F.). Twenty promising wheat cultivars were tested for resistance in non-choice conditions at the Department of Entomology, MSSSoA, Odisha during 2021-22. The wheat varieties were premeditated for their physical components through correlation analysis and the level of influence on insect preference and development was determined. The variety DBW303 which had a high median development period, low adult emergence and susceptible index was found to be resistant. Similarly, the variety PBW373 which recorded a low median developmental period with higher adult emergence, and susceptible index, was found to be susceptible. Among the physical traits, varieties with grain hardness exhibited a negative relationship with progeny development and thus conferred resistance.
