Population dynamics of Tribolium castaneum (Coleoptera: Tenebrionidae) in wheat and in wheat mixed with cracked wheat held in different types of containers.

The population dynamics of Tribolium castaneum (Herbst), red flour beetle, was studied at 30 °C using long vertical columns (LVCs) (150 mm diameter and 1,020 mm long) and shallow containers (SCs) (460 mm long, 660 mm wide, and 150 mm high), containing 14 kg of whole wheat or a diet made of whole wheat and cracked wheat in 19:1 ratio by mass. The moisture content of the wheat or mixed diet was 14.5% (wb).
