Abstract
Tests with mixtures of methyl bromide and carbon dioxide for the control of natural infestations and caged examples of stored-product pests (including Sitophilus zeamais Motsch., S. granarius (L.), Tribolium castaneum (Hbst.), Cryptolestes sp., Rhyzopertha dominica (F.) and Oryzaephilus surinamensis (L.)) were conducted in large silo bins containing stored grain (sorghum and maize) at 3 places in South Africa. Very high methyl bromide concentrations and a complete kill of insects were obtained at Settlers, where the carbon dioxide was applied as a gas. At Driefontein, where the carbon dioxide was applied as snow, and at Bloekonspruit, where it was applied as dry ice, the methyl bromide concentrations were much lower and some insect survival occurred. From the results of this work and of work in small bins in Israel, it appears that the size of the bin does not play an important role in the distribution of the gas mixture, but the way in which the carbon dioxide is applied is important. The logistic and economic implications of this result are discussed
