Abstract The effect of modified atmosphere packaging on the mortality of Sitophilus spp. in organic maize grain was studied. Maize grains were packed with five different atmospheres consisting of 20% O2, or 20, 40, 60, 80% CO2 with remaining N2. The packages were stored for 30 days at 26°C. CO2 and O2 concentrations were monitored inside the packages during the storage. The moisture content, titratable acidity and pH were analysed on the first and thirtieth day. At 5, 15 and 30 days of storage no significant differences were observed in the percentages of dead insects when CO2 was used. The results of progeny indicated that from the fifth day the number of emerging insects was low at 20, 60 and 80% CO2. Complete inhibition of the insects was achieved with 30 days of exposure in CO2 atmospheres.
