An attempt for developing an Integrated Pest Management (IPM) for the control of the groundnut bruchid, Caryedon serratus (Olivier) [Coleoptera: Bruchidae] on stored groundnut and tamarind in Yola, Adamawa State, Nigeria was evaluated. The experiment evaluated the different storage methods which were chemical (actellic dust) biological (bio-agent), cultural (plant materials) and controlled atmosphere (air - tight) and the combination of two or more of these methods. Combinations of Chemical + Plant material + air tight gave the highest mean percentage undamaged seeds (95.00 and 95.33), least mean percentage damaged seeds (5.00 and 4.67) and least percentage weight loss (2.33 and 2.00) for both groundnut and tamarind. The plant material, bio-agent and air-tight storage jars also had significant control on the bruchids compared to the control. Results showed that Mesostena pica (Kraatz) [Coleoptera: Tenebrionidae] could be used as a biological agent for the control of C. serratus in stored groundnut.
