Abstract

The maize weevil (Sitophilus zeamais) is an important cosmopolitan pest and the most detrimental insect of stored maize. This study aimed to investigate the efficacy of the periodic physical disturbance method on S. zeamais mortality. The potential adoption of the technology in Ghana was also considered. Farmers loaded 20 L buckets with maize grain and S. zeamais, non-hermetically. The physical disturbance was applied to the buckets twice a day for 30, 60 and 90 days. S. zeamais mortality was determined based on homogenized samples, and the analysis was done with one-way ANOVA. Generally, the physical disturbance method did not significantly cause S. zeamais mortality.

Key words: Periodic physical disturbance, Ghana, maize grain, Sitophilus zeamais, mortality.
