| 摘 要： | 利用立木磷化铝熏蒸、树干喷药、药剂涂环、打孔注药、饵木诱杀等方法，对红脂大小蠹进行了化学防治技术研究。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。利用树虫一针净、40％久效磷、40％氧化乐果打孔注药后第10d的防治效果均可达到80％以上，尤其利用一针净不仅携带方便、药效持久，而且无药液的挥发和流失，在成虫或幼虫盛发期使用每厘米胸径2．5mL的注入量可有效杀死侵入立木树干及根部的幼虫或成虫。

| Abstract: | The control of Dendroctonus valens in standing tree by applying insecticides was studied with some methods such as airtight fumigation with aluminum phosphide in plastic, spraying insecticide on trunk, tree-trunk injection, painting insecticide-ring, placing lured-wood and so on. 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. Compared with those methods, the tree-trunk injection was more practical to control this pest,the control efficiency achieved 80% with 40% monocrotophos, 40% omethoate and Yizhenjing after injection. Especially for Yizhenjing, it is easy to take, but the control efficiency was stand and can killing the pest that invaded into tree-root and tree-trunk of living pines with the dose of 2.5 mL each diameter breast height during the occurrence of adults and larvae. |
