Abstract

Research Aim: Nutritional indices and digestive proteolytic and amylolytic activity of Trogoderma granarium were evaluated on various cereal cultivars. Research method: In this research, effect of various cereal cultivars including wheat (cultivars N-91-9 and Aftab), barley (cultivars Dasht and Oxin), maize (cultivars AR and 704), and rice (cultivars Hashemi and Fajr) on nutritional indices and activity of digestive protease and amylase of T. granarium was studied at 33±1˚C, relative humidity of 65±5% and a photoperiod of 14: 10 (L: D). Findings: The results showed that the highest food consumption was observed in larvae fed on cultivar N-91-9 and the lowest value was observed on cultivars 704 and Fajr. The relative growth rate (RGR) was the highest on cultivars N-91-9 and Dasht. The highest proteolytic activity was in larvae fed on cultivars Aftab, Dasht and Hashemi; and the lowest activity was in those fed on cultivar Fajr. The highest amylolytic activity was observed on cultivars Dasht, N-91-9, Hashemi and AR; and the lowest value was on cultivars Oxin, Fajr, Aftab and 704. Conclusion: The results of nutritional indices and digestive protease and amylase activity of T. granarium larvae indicated that barley cultivar Oxin was an unfavorable host for feeding of T. granarium.
