Abstract
Controlled atmosphere were investigated as a substitute for conventional stored grain products. The effect of different gas mixtures containing different levels of carbon dioxide against adults and developmental stages of Callosobruchus maculatus at 25°C and 70% R. H. was studied. The adults of this species were more susceptible than the other stages to the tested modified atmospheres. Exposure to 75% CO2 in air for three days was sufficient to cause 100% mortality for eggs, larvae and pupae, whereas 50% CO2 was sufficient to kill 100% of adults.
