The order of tolerance to low O2 atmospheres produced by an exothermic inert atmosphere generator was Silophilus oryzae (L.) = S. granarius (L.) > Rhyzopertha dominica (F.) > Tribolium castaneum (Herbst) > Oryzaephilus surinamensis (L.). Time periods required to kiIl 50 and 95% of the adults of each species (LT) were computed from mortality data obtained in 1- to 240-h exposures at temperatures from 15 to 32°C. As the temperature increased from 15 to 32°C, the time required to obtain 50 and 95% mortality of the insects decreased ca. 90%. The highest LT95 was 296.7 h for S. oryzae at 15°C and the lowest 3.8 h for O. surinamensis at 32°C.
