Control of Insects with Fumigants at Low Temperatures: Toxicity of Mixtures of Methyl Bromide and Acrylonitrile to Three Species of Insects1

Acrylonitrile can be mixed with methyl bromide to increase toxicity so that the quantity of methyl bromide required for control of Sitophillus granarius (L.), Tenebrio molitor L., and Tribolium confusum Jacquelin duval is reduced by one half. Mixtures of methyl bromide and acrylonitrile are considerably more effective at low temperatures than methyl bromide alone.
