The influence of prior feeding experience and food deprivation on selection and utilization of wheat flour (WF), melon seed flour (MSF) and mung bean flour (MBF) by Tribolium castaneum reared on WF was investigated in this study. Flour selection, measured by percentage gravitation and acceptance of the flours by beetles (when fed and also when starved for 48 hours), was studied in choice and no-choice tests. On the other hand, T. castaneum’ s utilization of flours for growth and development was determined by monitoring population changes for three months in each flour type infested with 10 beetle pairs. Results of three-flour choice tests showed that gravitation (55.56%) and acceptance (54.44%) were significantly higher (p 0.05) from the control in the study. Flour utilization followed a similar trend with significantly higher (p < 0.05) mean adults and larvae numbers in WF (211.33, 81.33) and MBF (87.67, 31.00), respectively compared to MSF (28.33, 7.67) at three months after infestation. The study concluded that flour selection in T. castaneum is influenced by prior feeding experience but not by food deprivation status of the beetles. Flour utilization is, however, neither influenced by prior feeding experience nor by food deprivation.
