N2  - Efficacy of a modified atmosphere of different pressures of CO₂ N₂ and air gases at 28 ± 2°C, 60 ± 5% R.H. against different stages of each of S.oryzae, R. dominica and T. castaneum in addition to active and diapausing T-granarium larvae inside gastight steel cylinders was studied. The results indicated that, CO₂ was the best for controlling the tested insects when applied at 20 bar pressure for one hour- exposuring. The results showed also that, efficacy of gas increased with increasing the period of exposure or gas pressure. It could be concluded that, an exposure period at least 60 min. and a high pressure [20 bar] of CO₂ are necessary to achieve a complete extinction of populations of these insects
