SUMMARY1 The relation of this investigation to other problems connected with wood fumigation is indicated and previous work bearing on the subject is reviewed. 2 The technique is described by which the toxicity of hydrocyanic acid gas to certain wood‐feeding insects has been determined under standard conditions. 3 Results of experiments with Lyctus sp. larvae at 20 and 25° C. and with Lyctus brunneus beetles and Anobium punctatum larvae at 25° C. are given and resistance curves for different concentrations and exposures drawn from them. 4 The relative resistances and the toxicity relationships of the different insects are discussed. 5 Experiments with Lyctus larvae at 20 anu 25° C. show that the insects are more susceptible to HCN at the higher temperature. 6 At 25° C. Lyctus larvae are more susceptible to HCN than Lyctus beetles or Anobium larvae.
