Abstract We tested the efficacy of ethanedinitrile (EDN), a new fumigant considered as a potential methyl bromide (MB) replacement for the quarantine treatment of New Zealand pine, Pinus radiata D. Don, export logs. Firstly, toxicity trials were conducted in the laboratory with pine logs infested with the larvae, pupae, or adults of pine bark beetles, Hylurgus ligniperda and Hylastes ater, at 10 and 20 °C in 28-L chambers, to identify the most tolerant species and life stages. Then, logs infested with the most tolerant species and life stage were fumigated in 500-L laboratory chambers to determine whether the increase in the volume of the fumigated space and logs that will occur when scaling up from laboratory to commercial fumigations would affect EDN efficacy. Finally, confirmatory fumigation trials using commercial or semi-commercial sized log stacks, were conducted in a deforested commercial plantation area in Tokoroa, New Zealand, to demonstrate the efficacy of EDN in the field. Our results suggest EDN could be an effective alternative fumigant to MB for the phytosanitary treatment of logs exported from New Zealand. A phytosanitary fumigation schedule with EDN for P. radiata export logs that uses a concentration of 100 g/m3 for 20 h across a range of temperatures from 10 to 20 °C is recommended. Future efforts should focus on implementing the recommended schedule, under commercial practices, to provide quarantine security for export logs using EDN as a replacement for MB.

实验室毒性和大规模商业验证乙二腈(一种甲基溴的潜在替代熏蒸剂)对新西兰辐射松出口原木进行消毒的功效

摘要 我们测试了乙二腈 (EDN) 的功效,这是一种新的熏蒸剂,被认为是用于新西兰松(Pinus radiata D. Don)出口原木检疫处理的潜在甲基溴 (MB) 替代品。首先,在实验室中,在 10°C 和 20°C 的 28-L 室中对感染了松树皮甲虫 Hylurgus liggniperda 和 Hylastes ate 的幼虫、蛹或成虫的松木进行毒性试验,以确定最耐受的物种和人生阶段。然后,在 500 升实验室室中对感染了最耐受物种和生命阶段的原木进行熏蒸,以确定当从实验室熏蒸到商业熏蒸时,熏蒸空间和原木体积的增加是否会影响 EDN 功效。最后,在新西兰 Tokoroa 的一个砍伐森林的商业种植区中,使用商业或半商业大小的原木堆进行了验证性熏蒸试验,以证明 EDN 在该领域的功效。我们的结果表明,EDN 可能是一种有效的替代甲基溴的熏蒸剂,用于对从新西兰出口的原木进行植物检疫处理。建议使用 EDN 对辐射松出口原木进行植物检疫熏蒸计划,在 10 至 20 °C 的温度范围内使用 100 g/m3 的浓度进行 20 小时。未来的努力应侧重于在商业实践下实施推荐的时间表,以使用 EDN 替代 MB 为出口日志提供隔离安全。我们的结果表明,EDN 可能是一种有效的替代甲基溴的熏蒸剂,用于对从新西兰出口的原木进行植物检疫处理。建议使用 EDN 对辐射松出口原木进行植物检疫熏蒸计划,在 10 至 20 °C 的温度范围内使用 100 g/m3 的浓度进行 20 小时。未来的工作应侧重于在商业实践下实施推荐的时间表,为使用 EDN 替代 MB 的出口日志提供隔离安全。我们的结果表明,EDN 可能是一种有效的替代甲基溴的熏蒸剂,用于对从新西兰出口的原木进行植物检疫处理。建议使用 EDN 对辐射松出口原木进行植物检疫熏蒸计划,在 10 至 20 °C 的温度范围内使用 100 g/m3 的浓度进行 20 小时。未来的努力应侧重于在商业实践下实施推荐的时间表,以使用 EDN 替代 MB 为出口日志提供隔离安全。
