The impact of two predatory bugs, <i>Xylocoris flavipes</i> and <i>Joppeicus paradoxus</i>, on the stored-product insect, <i>Tribolium confusum</i>, was examined. Five pairs of adult <i>T. confusum</i> were placed in a plastic container (dia. 15 cm, height 8 cm) containing 10 g of whole-wheat flour. After 3 d, the following four experimental groups were set up: Control (no predator release), <i>X. flavipes</i> (four pairs of adult <i>X. flavipes</i> released), <i>J. paradoxus</i> (four pairs of adult <i>J. paradoxus</i> released), and <i>X. flavipes</i>+<i>J. paradoxus</i> (two pairs each of <i>X. flavipes</i> and <i>J. paradoxus</i> released). Twenty-five days after the release of the predatory insects, we counted the number of living <i>T. confusum</i>, <i>X. flavipes</i>, and <i>J. paradoxus</i>. The number of <i>T. confusum</i> in the <i>X. flavipes-</i>treated and <i>J. paradoxus</i>-treated groups was 3 and 33% of the control, respectively. On the other hand, the suppressive effect of <i>X. flavipes</i>+<i>J. paradoxus</i> treatment was lower than that of the above two treatments, probably due to intraguild predation between <i>X. flavipes</i> and <i>J. paradoxus</i>.
