摘　　要：2005年5-6月，在山西省屯兰川林场开展了不同配方高效引诱剂防治红脂大小蠹Dendroctonus valens LeConte试验，结果显示：β-蒎烯：α-蒎烯：3-蒈烯1：1：3或全部是3-蒈烯的两种配方为最佳配方，平均费用82．5元／hm^2。2006年5-7月，使用β-蒎烯：α-蒎烯：3-蒈烯为1：1：1配方的引诱剂对红脂大小蠹进行了防治，林木被害率下降64．5％，平均侵入孔数下降58．9％。High-effective attractants of different formulae were used in the control experiment against Dendroctonus valens in Tunlanchuan Forest Farm between May and June,2005. The results showed the formulae of β-Pinene, α- Pinene and 3-Carene in the proportion of 1 ： 1 ： 3 or pure 3-Carene were the best ones which cost 82.5 yuan/hm^2. The experiment against Dendroctonus valens with the formula of β-Pinene,α-Pinene and 3-Carene in the proportion of 1： 1：1 was made between May and June,2006. The infestation rate decreased by 64. 5% and the average number of invading holes decreased by 58. 9%.
