| Abstract | ||||
| Many stored grains and by-products become infested by the polyphagous pest, Trogoderma granarium Everts (Coleoptera: Dermestidae). The effect of eight leguminous commodities seeds (e.g. cowpea, faba bean, lentil, and kidney bean) and fruit nuts (e.g. cashew, almond, hazelnut, and walnut) on development, survival and reproduction of T. granarium was studied at conditions of 30 ± 1 °C, 65 ± 5% RH and a photoperiod of 14L: 10 D. Furthermore, all chemical components of the tested products were analyzed. The results implied that the examined commodities affected biological characteristics of T. granarium. The proportions of the internal components of the tested commodities varied, and the proximate analysis (%) varied among them. Biologically, the longest period of life cycle (egg-adult) of T. granarium was estimated on almonds (72.1±1.65 d) and the shortest one was on cowpea seed (45.4±1.47 d). The total oviposition period of T. granarium was the highest on cowpea seeds (12.9 d) and the lowest on almond (8.8 d). The highest fecundity and adult emergence rates were on cowpea seeds and the lowest was on almonds. The highest survival rate of larval and pupal stages was on faba bean seeds, and the lowest was on almond. Results revealed that both hazelnuts and walnuts were unsuitable food for the development of T. granarium beetles. | ||||
