A comparison of some effects of phosphine, hydrogen cyanide and anoxia in the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae)

The effects of phosphine, hydrogen cyanide and anoxia on levels of ATP, pyruvate and lactate in Rhyzopertha dominica are compared. The effect of phosphine on anaerobiosis is not directly comparable either with HCN or anoxia. Reduction of catalase by feeding 3 amino 1,2,4 triazole does not enhance the toxicity of phosphine in treated insects.
