Tribolium confusum Duv. Trogoderma granarium Everts Amphibolus venator predator Lasioderma serricorni Fab and Rhizopertha dominica F. under optimum laboratory conditions of Stored insect pests 27 1 C and 60 5 . The most preferable host was found to be R. dominica and L. serricorni larvae followed by T. confusum and P. interpunctella while the larvae of T. granarium appeared to be unsuitable host for this predator. ª 2015 Production and hosting by Elsevier . on behalf of Faculty of Agriculture Ain Shams University.

Several species of predatory bugs have been 165 days. Generally few available reviews were recorded studied as biological control agents such as Amphibolus venator about this predator. Therefore the present study was made Klug Peregrinator biannulipes Montrouzier and Signoret to evaluate its host preference on different stored product Joppeicus .
