The studies showed that the mean efficiency achieved 80% with aluminum phosphide in plastic, spraying insecticide on trunk and tree-trunk injection, placing lured-wood within woods could only lower pest amount to 28.3%, while the controlling effect was poor with painting insecticide-ring. 结果表明,立木磷化铝熏蒸、打孔注药、树干喷药等方法防治效果平均在80%以上,林内设置饵木可降低虫口数量28.3%,药剂涂环防治效果较差。
