Abstract

Adults of Sitophilus granarius, Tribolium castaneum, Oryzaephilus surinamensis, Cryptolestes ferrugineus and Rhyzopertha dominica on whole wheat, flour, rolled oats and yeast were exposed to simulated combusted atmospheres containing low O2 (0.5-2.6%) and increased CO2 (10-30%) with the balance N2 at 20 degree C and 70% RH. The mixtures containing 1-1.6% O2 killed all the insects within 7 days if they also contained greater than or equal 10% CO2. At 2.0-2.6% O2 C. ferrugineus was more tolerant of CO2 than the other insects tested, whereas at 0.5% O2 S. granarius was the most tolerant sp., needing 8-10 days for complete kill. The high CO2 atm is a useful method of pest control leaving no toxic residues.
