Entomotoxicity of Ethanedinitrile in Wood

The results of an experimental study of ethanedinitrile toxicity to insects inside the larval tunnels are described. Timber fumigation with ethanedinitrile at a dosage of 50 g/m³ for 24 h resulted in complete elimination of the adults of Sitophilus granarius L. inside larval tunnels in wood up to 9 cm deep.
