The adult stages of three key New Zealand forest pests burnt pine longhorn beetle (Arhopalus ferus) goldenhaired bark beetle (Hylurgus ligniperda) and black pine bark beetle (Hylastes ater) were fumigated at 10 or 20C for 4 h to determine their mortalities at increasing dosages of methyl bromide as a first step towards developing a new fumigation schedule for New Zealand export logs Hylastes adults were the most methyl bromide tolerant methyl bromide concentration required to control Hylastes adults is much lower than the phytosanitary requirement for export logs to India and China which requires 120 g/m3 for for logs exported from New Zealand but further work on other life stages is required
