Subject(s): Online resources: In: Journal of Agricultural Research Kafrelsheikh Univeristy 2007.v.33(4)Summary: The effects of some factors (gas composition, time of treatment and the role of oxygen concentration) affecting the efficiency of controlled atmospheres (CAs) against both C. maculatus and T. granarium were studied. The data confirmed that both C02 and N2 are quite safe and potent and could be uscd easily and successfully for controlling stored grain insects particularly in the presence of low concentration of oxygen. Pure CO2 is highly effective for controlling adults of C. maculatus with LT50 value of 19.85 hours, while T. granarium was relatively somewhat tolcrant towards pure CO2 with LTjo value of 46.81 hours. On the other hand, pure N2 was relatively fair toxic against C. maculatus with LTso value of 23.38 hours. Based on LT50 values,
