Ethanedinitrile: Potential methyl bromide alternative to control Arhopalus ferus (Mulsant) in New Zealand sawn timber exports

Abstract

The efficacy of ethanedinitrile (EDN, syn. cyanogen, EDN Fumigas®) for the control of burnt pine longhorn beetle (Arhopalus ferus (Mulsant)) adults was tested using a range of ethanedinitrile concentrations. The LD99for adults after a 3 h exposure at 15°C was 12.6 g/m3. The results demonstrate that ethanedinitrile is a potential phytosanitary alternative to methyl bromide for disinfesting burnt pine longhorn adults from sawn timber exported from New Zealand.
