Abstract
Maize (Zea mays) is an important staple food crop for consumption and income. However, weevils continue to endanger household food security. A study was carried out in Bahir Dar University, Ethiopia, in 2019/2020, to develop more accessible and effective hermetic storage systems. Purdue Improved Crop Storage System (PICS) is good, but it is neither accessible nor affordable in Ethiopia. Therefore, other materials were tested in a completely randomised design replicated three times. After 3 months, number of alive and dead weevils, number of seeds with holes/grain damage and weight loss were assessed and analyzed using one-way ANOVA. Malathion treated grains, PICS, polyethylene bags and jerry cans had low weevil infestation, more dead weevils and less grain damage. Mean number of weevils alive per sample varied from 0 on Malathion to 200 on woven polypropylene bags. PICS bags were effective but could be replaced by polyethylene bags and jerry cans.
