  "abstract": "<p>Advisor: Oljira Kenea (PhD)</p>\n\n<p>Maize (Zea mays L.) is originated in Central America and was introduced to West Africa in the early 1500s by the Portuguese traders. Today maize is one of the most important food crops worldwide including Ethiopia. In our country maize is produced mainly for maintaining food security. The maize weevil, S.zeamais is one of the most serious cosmopolitan insect of stored cereal grain, especially of maize in tropical and subtropical regions. The general objective of this study is to generate baseline information on the magnitude of maize weevil infestations on stored maize and postharvest control practices of smallholder farmers in Adet Zuria. In this study 200 quintal sample points from 20 households were taken at random for measuring the infestation rate of the maize weevil. One Way ANOVA was used to determine the weight loss of the maize taken at three different positions; bottom, middle and top positions. Postharvest storage management and maize weevil control practices were assessed using focus group discussion that consists of eight key informants. The infestation rates of maize weevil from 200 quintal sample sack store were 79.5%. From One way ANOVA it was found that there is statistical difference in the weight loss of the maize grain. From this the high weight loss was observed at the middle of the sack store and it has statistically significant difference with the weight loss at the bottom and the weight loss at the top. The management and control practices of maize weevil in sack storage most householders used synthetic chemicals. Results showed that the infestation rate of the maize weevil in sack stores was 79.5% from the sample of 200 quintals. It was also found that the weight loss of maize at the bottom, the middle and the top of the sack store were statistically significantly different. The major control and management practice of the local people against the maize weevil in AZK was chemical pesticides.
