Combined Effect of Hermetic Bag and Insect Resistant Variety for the Control of Larger Grain Borer and Maize Weevil in Stored Maize
Abstract: Combined effect of hermetic bag and varietal resistance was studied for control of Prostephanus truncatus and Sitophilus zeamais. Two maize varieties resistant (CKPH08028) and susceptible (PH3253) were used in combination with SuperGrain bag II-, PICS bag, Smartbag -1, Polypropylene bag and Actellic super dust. A mean of 5.2 % Carbon dioxide for both PICS and SuperGrain II- bags and 2.6 % for Smartbag -1 were recorded. PICS and SuperGrain II- bags suppressed insect population, prevented grain loss and cross - infestation of insects from the surrounding environment. Grain weight losses were 0.3 % in the PICS and 0.9 % in the SuperGrain IV-R- bags compared to 23.9 % in the polypropylene bags, 180 days after storage. No grain protection benefits were gained when either insect resistant (CKPH08028) or susceptible (PH5253) maize grains were stored in PICS or SuperGrain II- bags (
