Abstract

This research was conducted between midsummer and mid-fall (July and October, 2019). The study investigated the effectiveness of stirring infested maize in a farm-sized bin to control maize weevils (S. zeamaiz). Farm-sized steel grain bins have stirring machines suspended from the bin roof and sidewall with one or more vertical augers extending through the grain mass nearly to the bin drying floor. The augers rotate continuously through the grain mass lifting maize kernels from the bottom to the top of the bin, reducing the moisture gradient at different layers of the grain mass. The principle of using stirring augers to mix maize with insects has not been explored. The objective of this research was to determine effects of stirring weevil infested maize in a farm-sized bin on the population of maize weevils and quality of the maize.
