Abstract :

The Present Study Was Conducted To Assess The Resistance Of Selected Sorghum Varieties Against Tribolium Castaneum Under Storage Conditions, With The Aim Of Improving Grain Storage Management. Five Sorghum Varieties, Namely CSH-16, CSH-17, CSH-6, CSH- 15, And CSH-9, Were Evaluated Through Controlled Laboratory Bioassays Over Storage Periods Of 3, 6, 9, And 12 Months. The Parameters Studied Included Insect Population Buildup (insects·100 G⁻¹) And Percentage Grain-weight Loss. The Results Revealed A Progressive Increase In Insect Population And Grain Damage With The Advancement Of Storage Duration In All Varieties. Among The Tested Varieties, CSH-17 And CSH-9 Exhibited The Highest Insect Population (420.0 ± 15.6 And 390.0 ± 14.2 Insects·100 G⁻¹, Respectively, At 12 Months) And Maximum Weight Loss (29.5 ± 1.8% And 27.8 ± 1.7%, Respectively), Indicating Their Susceptibility. In Contrast, CSH-6 And CSH-15 Showed Comparatively Lower Infestation Levels And Reduced Grain Damage, Suggesting Their Resistance To T. Castaneum. CSH-16 Exhibited Moderate Susceptibility. A Strong Positive Correlation Was Observed Between Insect Population Density And Grain Weight Loss. The Study Highlights The Importance Of Varietal Selection In Minimizing Post-harvest Losses And Suggests That Resistant Sorghum Varieties Can Serve As An Effective Strategy For Sustainable Grain Storage Management.
