Comparative effectiveness of GrainPro Cocoon TM with traditional storage systems against Tribolium castaneum (Hbst.), Rhyzopertha dominica (F.) and Sitophilus oryzae (L.)

TM , Thick Waterproof Cloth Sheath, Simple Polythene Sheath and control) were used. Each storage structure was tested for three storage periods viz. 5, 10 and 15 days. The results of the trial indicated the cumulative mean mortality of the stored pests (16%) in Grainpro Cocoon TM and was significantly higher (p < 0.05) compared with the thick waterproof cloth sheath (4%), simple polythene sheath (8%) and control (0%). Further analysis suggested that the T. castaneum was most venerable in the Grainpro Cocoon TM but R. dominica was observed to be resistant
