Tribolium castaneum and Rhyzopertha dominica adults and eggs were exposed to atmospheres containing 2%-8% O2, supplemented with 5%-30% CO2 at 26°C and 55% r.h. for 24-144 h. Eggs of both species were more susceptible than their adult stage to low O2 concentrations per se as well as to the O2 and CO2 mixtures tested. R. dominica eggs were more tolerant than T. castaneum eggs to the above treatments.
Addition of CO2 to low O2 atmospheres resulted in a synergistic effect on adult mortality of both species, while there was only an additive effect on the eggs exposed to the same treatments.
These results provide additional information to be considered in the use of controlled atmospheres for grain storage.
