520			_aThe effect of controlled atmospheres (CAs) of 30 and 60% CO₂ or 99.9% N₂ at various temperatures (15, 20,25, 30 or 35°C) and 60±5% R.H. was investigated on all developmental stages of Triboleum castaneum (Herbst) and active or diapausing larvae of Trogoderma granarium Everts). For Triboleum castaneum the egg stage was the most sensitive to CO₂ at all tested temperatures. LT₉₉S reduced from 3.8 days at 15°C to 2.8 days at 35°C under 30% CO₂ and from 3.2 days at 15°C to 2.5 days at 35°C under 60% CO₂. The susceptibility of pupal stage occupied the second range after the egg stage at all tested temperatures and CO₂ concentrations. The larval stage was the least sensitive to 30% CO₂ at all tested temperatures and at 25, 30, 35°C to 60% CO₂ (LT₉₉S shortened from 16.6 days at 15°C to 5 days at 35°C under 30% CO₂ and to 3.1 days at 35°C under 60% CO₂). The adult stage was only the least sensitive to 60% CO₂ at 15°C and 20°C (LT₉₉S decreased from 7.1 days at 15°C to 5.6 days at 20°C). Under CA of 99.9% N₂ the larval and adult stages were the most sensitive at 15 to 30°C while the pupal and egg stages were the least sensitive. For Trogoderma granarium, the active larvae were more susceptible than the diapausing larvae only when exposed to 60% CO₂ at all tested temperatures and 99.9% N₂ at 35°C. LT₉₉S of active larvae decreased from 20.1 days at 15°C to 7.9 days at 35°C under 60% CO₂ and to 9.2 days at 35°C under 99.9% N₂, LT₉₉S of diapausing larvae decreased from 43.4 days at 20°C to 9.1 days at 35°C under 60% CO₂ and to 12.1 days at 35°C under 99.9% N₂.
